Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object (...) noun and whether this ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load. (shrink)

Rhythmic structure in speech is characterized by sequences of stressed and unstressed syllables. A large body of literature suggests that speakers of English attempt to achieve rhythmic harmony by evenly distributing stressed syllables throughout prosodic phrases. The question remains as to how speakers plan metrical structure during speech production and whether it is planned independently of phonemes. To examine this, we designed a tongue twister task consisting of disyllabic word pairs with overlapping phonological segments and either matching or (...) non‐matching metrical structure. Results showed that speakers had more difficulty producing metrically regular word pairs, compared to irregular pairs; that is, word pairs with irregular meter had faster productions and fewer speech errors in this production task. This finding of metrical regularity inhibiting production is inconsistent with an abstract metrical structure that is planned independently of phonemes at the point of phonological encoding.

Although previous research has shown that there exist individual and cross-linguistic differences in planning strategies during language production, little is known about how such individual differences might vary depending on which language a speaker is planning. The present series of studies examines individual differences in planning strategies exhibited by speakers of American English, French, and German. Participants were asked to describe images on a computer monitor while their eye movements were monitored. In addition, we measured participants' working (...) memory capacity and speed of processing. The results indicate that in the present study, English and German were planned less incrementally (further in advance) prior to speech onset compared to French, which was planned more incrementally (not as far in advance). Crucially, speed of processing predicted the scope of planning for French speakers, but not for English or German speakers. These results suggest that the different planning strategies that are invoked by syntactic choices available in different languages are associated with the tendency for speakers to rely on different cognitive support systems as they plan sentences.

Experimental studies of speech production involving compensations for auditory and somatosensory perturbations and adaptation after training suggest that both types of sensory information are considered to plan and monitor speech production. Interestingly, individual sensory preferences have been observed in this context: subjects who compensate less for somatosensory perturbations compensate more for auditory perturbations, and \textit{vice versa}. We propose to integrate this sensory preference phenomenon in a model of speech motor planning using a probabilistic model in which (...) speech units are characterized both in auditory and somatosensory terms. Sensory preference is implemented in the model according to two approaches. In the first approach, which is often used in motor control models accounting for sensory integration, sensory preference is attributed to the relative precision (i.e., inverse of the variance) of the sensory characterization of the speech motor goals associated with phonological units (which are phonemes in the context of this paper). In the second, ``more original’’ variant, sensory preference is implemented by modulating the sensitivity of the comparison between the predicted sensory consequences of motor commands and the sensory characterizations of the phonemes. We present simulation results using these two variants, in the context of the adaptation to an auditory perturbation, implemented in a 2-dimensional biomechanical model of the tongue. Simulation results show that both variants lead to qualitatively similar results. Distinguishing them experimentally would require precise analyses of partial compensation patterns. However, the second proposed variant implements sensory preference without changing the sensory characterizations of the phonemes. This dissociates sensory preference and sensory characterizations of the phonemes, and makes the account of sensory preference more flexible. Indeed, in the second variant the sensory characterizations of the phonemes can remain stable, when sensory preference varies as a response to cognitive or attentional control. This opens new perspectives for capturing speech production variability associated with aging, disorders and speaking conditions. (shrink)

This paper explores the truism that people think about what they say. It proposes that, to satisfy their own goals, people often plan their speech acts to affect their listeners' beliefs, goals, and emotional states. Such language use can be modelled by viewing speech acts as operators in a planning system, thus allowing both physical and speech acts to be integrated into plans. Methodological issues of how speech acts should be defined in a planbased theory (...) are illustrated by defining operators for requesting and informing. Plans containing those operators are presented and comparisons are drawn with Searle's formulation. The operators are shown to be inadequate since they cannot be composed to form questions (requests to inform) and multiparty requests (requests to request). By refining the operator definitions and by identifying some of the side effects of requesting, compositional adequacy is achieved.The solution leads to a metatheoretical principle for modelling speech acts as planning operators.

Developmental stuttering is a widely discussed speech fluency disorder. Research on its mechanism has focused on an atypical interface between the planning (PLAN) and execution (EX) processes, known collectively as the EXPLAN model. However, it remains unclear how this atypical interface influences people who stutter. A straightforward assumption is that stuttering speakers adopt a smaller scope of speech planning, whereas a defect in word retrieval can be confounding. To shed light on this issue, we took the (...) semantic blocking effect as an index to examine lexical planning in word and phrase production. In Experiment 1, for word production, pictures from the same semantic category were combined to form homogeneous blocks, and pictures from different categories were combined to form heterogeneous blocks. A typical effect of semantic blocking showing longer naming latencies for homogeneous blocks than heterogeneous ones was observed for both stuttering and fluent speakers. However, this effect was smaller for stuttering speakers, when it was subject to lexical defects in stuttering. In Experiment 2, for a conjoined noun phrase production task, the pictures referring to the first noun were manipulated into homogeneous and heterogeneous conditions. The semantic blocking effect was also much smaller for stuttering speakers, indicating a smaller scope of lexical planning. Therefore, the results provided more evidence in support of the EXPLAN model and indicated that a smaller scope of lexical planning rather than lexical defects causes the atypical interface for stuttering. Moreover, a comparison between these two tasks showed that the study findings have implications for syntactic defects in stuttering. (shrink)

An alternative account of the locus equation phenomenon based on recent theories of speech movement planning is provided. It is similar to Sussman et al.'s account in positing that our productions are tuned to satisfy auditory constraints. It differs by suggesting that the locus equation effect may be an epiphenomenon of a planning process that satisfies simpler auditory constraints.

Research on language production has focused on the process of utterance planning and involved studying the synchronization between visual gaze and the production of sentences that refer to objects in the immediate visual environment. However, it remains unclear how the visual grouping of these objects might influence this process. To shed light on this issue, the present research examined the effects of the visual grouping of objects in a visual display on utterance planning in two experiments. Participants produced (...) utterances of the form “The snail and the necklace are above/below/on the left/right side of the toothbrush” for objects containing these referents (e.g., a snail, a necklace and a toothbrush). These objects were grouped using classic Gestalt principles of color similarity (Experiment 1) and common region (Experiment 2) so that the induced perceptual grouping was congruent or incongruent with the required phrasal organization. The results showed that speech onset latencies were shorter in congruent than incongruent conditions. The findings therefore reveal that the congruency between the visual grouping of referents and the required phrasal organization can influence speech production. Such findings suggest that, when language is produced in a visual context, speakers make use of both visual and linguistic cues to plan utterances. (shrink)

The goal of this thesis is to model some of the cognitive structures and processes involve d in how people decide what to say in purposeful conversation. The main concern is to show how a speaker's knowledge of his/her hearer influences what s/he says. Utterances in such dialogues, where speakers can be presumed to be speaking for reasons, can best be viewed as the performance of "speech acts" (e.g., requesting). By modeling the process of deciding what to say as (...) one of problem-solving, we show that the same mechanisms used to plan non-linguistic actions are applicable to planning of speech acts. The methodology of this research employs a computer program that integrates beliefs, goals, problem-solving, and reasoning, with the use of language. The program does this by planning speech acts when it determines that to achieve its situational goals, it needs to influence someone else's behavior. The system is able to plan request speech actrions to influence its user's goals, and inform speech acts to influence his/her beliefs. In addition, it is shown that speech acts can be used to achieve subgoals of other such acts. For instance, in addition to requesting that the user perform some action, the system can also decide to supply him/her with information necessary to performing that action -- information that it believes s/he does not already have. Our model is extendable to the more general problem of planning multiparty speech acts -- ones where actions requested by the speaker involve acts to be performed by parties other than the hearer.

We investigate the timing of pre-answer inbreaths in order to shed light on the time course of response planning and execution in conversational turn-taking. Using acoustic and inductive plethysmography recordings of seven dyadic conversations in Dutch, we show that pre-answer inbreaths in conversation typically begin briefly after the end of questions. We also show that the presence of a pre-answer inbreath usually co-occurs with substantially delayed answers, with a modal latency of 576 vs. 100 ms for answers not preceded (...) by an inbreath. Based on previously reported minimal latencies for internal intercostal activation and the production of speech sounds, we propose that vocal responses, either in the form of a pre-utterance inbreath or of speech proper when an inbreath is not produced, are typically launched in reaction to information present in the last portion of the interlocutor's turn. We also show that short responses are usually made on residual breath, while longer responses are more often preceded by an inbreath. This relation of inbreaths to answer length suggests that by the time an inbreath is launched, typically during the last few hundred milliseconds of the question, the length of the answer is often prepared to some extent. Together, our findings are consistent with a two-stage model of response planning in conversational turn-taking: early planning of content often carried out in overlap with the incoming turn, and late launching of articulation based on the identification of turn-final cues.

Free speech fallacies are errors of meta-argument. One commits a free speech fallacy when one argues that since there are apparent restrictions on one’s rights of free expression, procedural rules of critical exchange have been broken, and consequently, one’s preferred view is dialectically better off than it may otherwise seem. Free speech fallacies are meta-argumentative, since they occur at the level of assessing the dialectical situation in terms of norms of argument and in terms of meta-evidential principles (...) of interpreting how and why people follow (or fail to follow) argumentative rules. Our plan here is to begin with a brief explanation of meta-argument and meta-argumentative fallacy. We will then turn to the variety of forms of the free speech fallacy, which we will explain as meta-argumentatively erroneous. (shrink)

A broad sketch for a model of speech production is outlined which describes developmental aspects of its cognitive-linguistic and sensorimotor components. A description of the emergence of phonological knowledge is a central point in our model sketch. It will be shown that the phonological form level emerges during speech acquisition and becomes an important representation at the interface between cognitive-linguistic and sensorimotor processes. Motor planning as well as motor programming are defined as separate processes in our model (...) sketch and it will be shown that both processes revert to the phonological information. Two computational simulation experiments based on quantitative implementations are undertaken to show proof of principle of key ideas of the model sketch: the emergence of phonological information over developmental stages, the adaptation process for generating new motor programs, and the importance of various forms of phonological representation in that process. Based on the ideas developed within our sketch of a production model and its quantitative spell-out within the simulation models, motor planning can be defined here as the process of identifying a succession of executable chunks from a currently activated phoneme sequence and of coding them as raw gesture scores. Motor programming can be defined as the process of building up the complete set of motor commands by specifying all gestures in detail. This full specification of gesture scores is achieved in our model by adapting motor information from phonologically similar syllables or by assembling motor programs from sub-syllabic units.

This essay expounds on Raphael Cohen-Almagor’s recent book, Confronting the Internet’s Dark Side, Moral and Social Responsibility on the Free Highway, and advocates placing narrow limitations on hate speech posted to social media websites. The Internet is a limitless platform for information and data sharing. It is, in addition, however, a low-cost, high-speed dissemination mechanism that facilitates the spreading of hate speech including violent and virtual threats. Indictment and prosecution for social media posts that transgress from opinion to (...) inciteful hate speech are appropriate in limited circumstances. This article uses various real-world examples to explore when limitations on Internet-based hate speech are appropriate. In October 2015, twenty thousand Israelis joined a civil lawsuit filed against Facebook in the Supreme Court for the State of New York. Led by the civil rights organization, Shurat HaDin, the suit alleges Facebook allows Palestinian extremists to openly recruit and train terrorists to plan violent attacks calling for the murder of Israeli Jews through their Facebook pages. The suit raises important questions, amongst them: When should the government initiate similar suits to impose criminal sanctions for targeted hate speech posted to Facebook? What constitute effective restrictions on social media that also balance society’s need for robust dialogue and free communication, subject to limitations reflecting a need for order and respect among people? Our essay progresses in four stages. First, we examine philosophical origins of free speech and the historical foundations of free speech in the United States. Second, we provide an overview of American free speech jurisprudence. Third, we address particular jurisprudence that provides a framework for imposing limitations on free speech in the context of social media. American history and jurisprudence embrace free speech as a grounding principle of democracy, yet simultaneously subject speech to limitations. Finally, through a comparative exploration of real-world examples, we address the narrow instance when limitations on inciteful and targeted hate speech are appropriate. (shrink)

Despite the recent advances in information and communication technology that have increased our ability to store and circulate information, the task of ensuring that the right sorts of information gets to the right sorts of people remains. We argue that the many efforts underway to develop efficient means for sharing information across healthcare systems and organizations would benefit from a careful analysis of human action in healthcare organizations. This in turn requires that the management of information and knowledge within healthcare (...) organizations be combined with models of resources and processes of patient care that are based on a general ontology of social interaction. The Health Level 7 (HL7) is one of several ANSI-accredited Standards Developing Organizations operating in the healthcare arena. HL7 has advanced a widely used messaging standard that enables healthcare applications to exchange clinical and administrative data in digital form. HL7 focuses on the interface requirements of the entire healthcare system and not exclusively on the requirements of one area of healthcare such as pharmacy, medical devices, imaging or insurance transactions. This has inspired the development of a powerful abstract model of patient care called the Reference Information Model (RIM). The present paper begins with an overview of the core classes of the HL7 (Version 3) RIM and a brief discussion of its “actcentered” view of healthcare. Central to this account is what is called the life cycle of events. A clinical action may progress from defined, through planned and ordered, to executed. These modalities of an action are represented as the mood of the act. We then outline the basis of an ontology of organizations, starting from the theory of speech Acts, and apply this ontology to the HL7 RIM. Special attention is given to the sorts of preconditions that must be satisfied for the successful performance of a speech act and to the sorts of entities to which speech acts give rise (e.g. obligations, claims, commitments, etc.). Finally we draw conclusions for the efficient communication and management of medical information and knowledge within and between healthcare organizations, paying special attention to the role that medical documents play in such organizations.

Hate speech, understood broadly, is any form of expression intended to arouse hatred or contempt toward members of a particular social group. When university administrators have reason to believe that a planned speaking event on campus may feature hate speech (at least in the eyes of some), how should they respond? In this paper I address this question as it arises for Canadian universities. I argue that, where the regulation of campus speech is concerned, the right course (...) of action for university administrators is nearly always to do absolutely nothing. They will have reason to become actively involved only in order to ensure that a speaking event proceeds safely, or when it threatens to disrupt the functioning of the university, or when it is itself threatened with disruption by protesting groups. In those instances the justification for intervention will be to protect and facilitate speech, not to shut it down. (shrink)

Uttered language does not necessarily reflect the planned communications of schizophrenia patients, nor do their delusions necessarily reflect basic failures of inferential reasoning. The role of inhibitory failure in the production of speech and the role of primary experiences of discrepancy between intention and action, and between experience–based expectations and perceived realities account for many of the clinical phenomena that have led to the conclusion that these patients have a ‘thought’ disorder, or a ‘disturbed’ mind. The alternatives and the (...) evidence are summarized in this paper. (shrink)

Free will typically refers to any form of significant control over one’s actions. This definition is remarkably similar to that of self-regulation—the control of one’s behavior, emotions, and thoughts in pursuit of long-term goals. Indeed, several scholars have proposed that the latter constitutes the psychological equivalent of the former. A large body of empirical work demonstrates that both covert (inner) and overt (private) forms of self-directed speech are causally associated with self-regulatory outcomes such as action planning, problem-solving, emotion (...) regulation, attention, cognitive flexibility, working memory, and self-reflection. It thus seems logical to propose that free will too recruits self-directed speech. This argument is explored by reviewing the relevant literature pertaining to free will, self-regulation, and inner/private speech. More specifically, free will is defined and contrasted with self-regulation, whose definition ends up being remarkably similar. Examples of typical research on private and inner speech are presented and show a key involvement of self-directed speech in self-regulation. The notion that free will depends on inner speech is further explored based on Wiley’s work (2009). One outstanding implication is that individual differences in self-directed speech use could be linked to different levels of free will. That is, people using inner/private speech more efficiently could exhibit freer will, and vice-versa. (shrink)

The essential insight of speech act theory was that when we use language, we perform actions—in a more modern parlance, core language use in interaction is a form of joint action. Over the last thirty years, speech acts have been relatively neglected in linguistic pragmatics, although important work has been done especially in conversation analysis. Here we review the core issues—the identifying characteristics, the degree of universality, the problem of multiple functions, and the puzzle of speech act (...) recognition. Special attention is drawn to the role of conversation structure, probabilistic linguistic cues, and plan or sequence inference in speech act recognition, and to the centrality of deep recursive structures in sequences of speech acts in conversation.

Many studies have documented a close timing relationship between speech prosody and co-speech gesture, but some studies have not, and it is unclear whether these differences in speech-gesture alignment are due to different speaking tasks, different target gesture types, different prosodic elements, different definitions of alignment, or even different languages/speakers. This study contributes to the ongoing effort to elucidate the precise nature of the gesture–speech timing relationship by examining an understudied variety of American English, i.e., academic-lecture-style (...) speech, with a focus on an understudied type of gesture: Non-Referential gestures, which make up the majority of this corpus. Results for the 1,334 Stroke-Defined Gestures in this 20-min sample suggest that the stroke phase of a Non-Referential gesture tends to align with a pitch-accented syllable, just as reported in studies of other gesture types (e.g., deictic gestures) and in other speaking styles (such as narration). Preliminary results are presented suggesting that trajectory shapes of these Non-Referential gestures are consistent across a higher-level prosodic grouping, supporting earlier proposals for kinematic constancy across spoken prosodic constituents ( Kendon, 1972, 1980, 2004 ). Analysis also raises the possibility that the category of Non-Referential gestures is not solely made up of ‘beats,’ defined as simple bi-phasic flick-like movements that beat out the rhythm of the speech, but includes gestures with multiple phases and various types of rhythmicity. Taken together, the results of this analysis suggest (1) a wide range of gesture configurations within the undifferentiated category of Non-Referential gestures or ‘beats,’ which requires further investigation, and (2) a close coordination between co-speech gestures and the prosodic structure of spoken utterances across speaking styles and gesture referentiality, which has profound implications for modeling the process of planning an utterance.

Past research has sought to elucidate how speakers and addressees establish common ground in conversation, yet few studies have focused on how visual cues such as co-speech gestures contribute to this process. Likewise, the effect of cognitive constraints on multimodal grounding remains to be established. This study addresses the relationship between the verbal and gestural modalities during grounding in referential communication. We report data from a collaborative task where repeated references were elicited, and a time constraint was imposed to (...) increase cognitive load. Our results reveal no differential effects of repetition or cognitive load on the semantic-based gesture rate, suggesting that representational gestures and speech are closely coordinated during grounding. However, gestures and speech differed in their execution, especially under time pressure. We argue that speech and gesture are two complementary streams that might be planned in conjunction but that unfold independently in later stages of language production, with speakers emphasizing the form of their gestures, but not of their words, to better meet the goals of the collaborative task.

Inner speech has been shown to vary in form along several dimensions. Along condensation, condensed inner speech forms have been described, that are supposed to be deprived of acoustic, phonological and even syntactic qualities. Expanded forms, on the other extreme, display articulatory and auditory properties. Along dialogality, inner speech can be monologal, when we engage in internal soliloquy, or dialogal, when we recall past conversations or imagine future dialogs involving our own voice as well as that of (...) others addressing us. Along intentionality, it can be intentional (when we deliberately rehearse material in short-term memory) or it can arise unintentionally (during mind wandering). We introduce the ConDialInt model, a neurocognitive predictive control model of inner speech that accounts for its varieties along these three dimensions. ConDialInt spells out the condensation dimension by including inhibitory control at the conceptualization, formulation or articulatory planning stage. It accounts for dialogality, by assuming internal model adaptations and by speculating on neural processes underlying perspective switching. It explains the differences between intentional and spontaneous varieties in terms of monitoring. We present an fMRI study in which we probed varieties of inner speech along dialogality and intentionality, to examine the validity of the neuroanatomical correlates posited in ConDialInt. Condensation was also informally tackled. Our data support the hypothesis that expanded inner speech recruits speech production processes down to articulatory planning, resulting in a predicted signal, the inner voice, with auditory qualities. Along dialogality, covertly using an avatar’s voice resulted in the activation of right hemisphere homologs of the regions involved in internal own-voice soliloquy and in reduced cerebellar activation, consistent with internal model adaptation. Switching from first-person to third-person perspective resulted in activations in precuneus and parietal lobules. Along intentionality, compared with intentional inner speech, mind wandering with inner speech episodes was associated with greater bilateral inferior frontal activation and decreased activation in left temporal regions. This is consistent with the reported subjective evanescence and presumably reflects condensation processes. Our results provide neuroanatomical evidence compatible with predictive control and in favor of the assumptions made in the ConDialInt model. (shrink)

This volume of The Writings and Speeches of Edmund Burke continues the story of Edmund Burke, the Rockingham party in British politics, and the American crisis. By 1774 Burke was already recognized as a master of parliamentary debate and an accomplished writer. By 1780, however, his reputation was to have risen substantially. Probably the most important single reason was his Speech on Conciliation with America, which was presented to the House of Commons in March 1775, published, and circulated to (...) a wide audience on both sides of the Atlantic. In that speech, Burke used the full force of his intellect and eloquence to set out the Rockinghams' first comprehensive plan for achieving lasting peace in the Empire. The public commendation he received helped him to gain recognition for offerings such as his second conciliation proposal in November 1775, and his Letter to the Sheriffs of Bristol in 1777. It also gave him some of the confidence he needed to announce the Whig party's historic conversion to a moderate reform programme in his celebrated speeches on economical reform in 1779 and 1780. Numerous writings and speeches in this volume are transcriptions of previously unpublished manuscripts from the collections at Sheffield and Northampton. These allow the reader new insights into the workings of Burke's mind not just in relation to the major political issues, but also to a multitude of engaging subjects such as education, capital punishment, religious dissent, and the return of the Rockingham Whigs to government power.

Temporal patterns in human movement, and in speech in particular, occur on multiple timescales. Regularities in such patterns have been observed between speech gestures, which are relatively quick movements of articulators (e.g., tongue fronting and lip protrusion), and also between rhythmic units (e.g., syllables and metrical feet), which occur more slowly. Previous work has shown that patterns in both domains can be usefully modeled with oscillatory dynamical systems. To investigate how rhythmic and gestural domains interact, an experiment was (...) conducted in which speakers performed a phrase repetition task, and gestural kinematics were recorded using electromagnetic articulometry. Variance in relative timing of gestural movements was correlated with variance in rhythmic timing, indicating that gestural and rhythmic systems interact in the process of planning and producing speech. A model of rhythmic and gestural planning oscillators with multifrequency coupling is presented, which can simulate the observed covariability between rhythmic and gestural timing. (shrink)

Current models of speech motor control rely on either trajectory-based control (DIVA, GEPPETO, ACT) or a dynamical systems approach based on feedback control (Task Dynamics, FACTS). While both approaches have provided insights into the speech motor system, it is difficult to connect these findings across models given the distinct theoretical and computational bases of the two approaches. We propose a new extension of the most widely used dynamical systems approach, Task Dynamics, that incorporates many of the strengths of (...) trajectory-based approaches, providing a way to bridge the theoretical divide between what have been two separate approaches to understanding speech motor control. The Task Dynamics (TD) model posits that speech gestures are governed by point attractor dynamics consistent with a critically damped harmonic oscillator. Kinematic trajectories associated with such gestures should therefore be consistent with a second-order dynamical system, possibly modified by blending with temporally overlapping gestures or altering oscillator parameters. This account of observed kinematics is powerful and theoretically appealing, but may be insufficient to account for deviations from predicted kinematics—i.e., changes produced in response to some external perturbations to the jaw, changes in control during acquisition and development, or effects of word/syllable frequency. Optimization, such as would be needed to minimize articulatory effort, is also incompatible with the current TD model, though the idea that the speech production systems economizes effort has a long history and, importantly, also plays a critical role in current theories of domain-general human motor control. To address these issues, we use Dynamic Movement Primitives (DMPs) to expand a dynamical systems framework for speech motor control to allow modification of kinematic trajectories by incorporating a simple, learnable forcing term into existing point attractor dynamics. We show that integration of DMPs with task-based point-attractor dynamics enhances the potential explanatory power of TD in a number of critical ways, including the ability to account for external forces in planning and optimizing both kinematic and dynamic movement costs. At the same time, this approach preserves the successes of Task Dynamics in handling multi-gesture planning and coordination. (shrink)

The proposed model consists of 1) a Phonological Planning Component to plan the symbolic and relational goals for an utterance, 2) a Phonetic Planning Component to plan the quantitative details of the acoustic goals and how they will be achieved articulatorily, and 3) a Motor-Sensory Implementation Component to ensure that the goals are achieved on time. The temporal characteristics specified in the Phonetic Planning Component include durations between acoustic landmarks, as well as parameters of Lee’s TauG-Guidance equation, (...) which determine how a movement evolves over time. Movement coordination is assumed to be based on movement endpoints (rather than onsets) and accomplished via Tau-coupling (Lee 1998). Both the Phonetic Planning and Motor-Sensory Implementation components are assumed to make use of general-purpose, phonology-extrinsic, timekeeping mechanisms to represent, specify, and track time. Supporting evidence includes greater timing precision at movement endpoints compared to other parts of movements, suggesting the separate control of the timing of movement endpoints compared to other parts of movement. This evidence challenges models in which all parts of a movement trajectory are controlled by the same equation of motion, but supports models in which a) each abstract, symbolic phonological representation maps onto spatial and temporal characteristics of the part(s) of movement most closely related to the goal of producing a planned set of acoustic cues to signal the phonological contrast (often the endpoint), b) movements are coordinated primarily based on the goal-related part of movement, and c) speakers give priority to the accurate implementation of the part(s) of movement most closely related to the phonological goals. Further support for phonology-extrinsic timing comes from three types of evidence suggesting that surface durations are represented during speech production. Finally, phonology-extrinsic timing is supported by greater timing variability for repetitions of longer intervals, assumed to be due to noise in a general-purpose (and phonology-extrinsic) timekeeping process. The evidence appears to be incompatible with models that have a unified Phonology/Phonetics Component, with models which do not represent the surface timing of phonetic events, nor with models in which timing in speech production is not represented, specified and tracked by a general-purpose timekeeping mechanisms.

The article discusses mechanisms of manipulative influence on a theoretical basis of suggestion and on the actual material of Bulgarian press. The author supposes that adequate research requires integrated approach with symbiosis of techniques of cognitive science, linguistic pragmatics, psycholinguistics and the theory of speech activity. Manipulative action takes place not only through language (explicit and implicit), but also non-verbal instruments that have different range, different pragmatic potential, etc. The necessity of a comprehensive analysis of the hidden manipulative influence (...) on psyche which is implemented through a flexible system of complex-integrated manipulative pragmatic acts is stated. This system is projected to complete, hierarchically organized and fast changing communication technology which has the following form: cognitive and psychological basis of audience → intention of the adresser → communication strategy → verbal tactics → instruments → perlocutionary effect. Herewith the form of speech is one of the pragmatic factors having great value for actualizing manipulative potential. Communication in form of direct dialog, typical only for oral speech, has a significant resources to counter planned suggestion. Furthermore the author compares the usage of the same suggestive influence patterns in oral and written speech. So the monologue tactic is supposed to be optimal for planning and control of communicative intention, which may include the use of instruments and mechanisms with manipulative potential. Addresser has sufficient time for careful selection of communication strategies and tactics of speech, as well as for creative combination and skillful concealing of manipulativeness manifestations. The author concludes that the regularity, according to which one monologue makes manipulativeness ''tolerant'' and dialogue ''discredit'' it, reflects differently in different monologue and dialogue tactics that are relevant to different types of communicative interaction.

Recent state regulations require women, before undergoing abortions, to be subjected to unwanted and nonmedically necessary sonograms, often requiring an intrusive vaginal probe. Physicians, for their part, are forced to turn the viewing screens toward the faces of their patients and to describe to them the details on the screen.

In lieu of an abstract, here is a brief excerpt of the content:The World as I Found It:Possibilities and Peculiarities about Speech and ConversationDavid WemyssIn November 2002, a series of tutorials was advertised within the University of Cambridge. Neville Critchley—a lecturer in philosophy with a reputation for preferring literature—placed advertisements on college notice boards saying he wanted to hear from students not just philosophically or intellectually intrigued by language but literally made unwell by it. Four young people replied, one (...) of whom subsequently provided me with an account of what passed in Room C28 at Emmanuel College. Almost thirteen years afterwards, the account was published under the title "The Weighing of Our Words."1Richard Salisbury, who had prepared the account, died in September 2016. His later piece, "A Report on Experience,"2 was published in October 2018—and that was believed to be the last literary production connected with the 2002 tutorials. However, it transpires that Richard's wife, Carole, who had organized the publication of "A Report on Experience," was also in possession of an intriguing recording from June 2016—just months before Richard's death. Carole discovered an audio recording, on a set of old-fashioned, reel-to-reel tapes, of a meeting in the Bedford Hotel in Bloomsbury, London, between her husband and Neville Critchley—fourteen years after they had last met. The conversation was [End Page 210] clearly intended to be transcribed and published, and I remain grateful to Carole for her help and friendship in arranging this.INeville Critchley and Richard SalisburyBedford Hotel, Southampton Row, LondonJune 2016Neville Critchley:Sitting here in Bloomsbury, I'm remembering the story about T. S. Eliot hiding in the lavatory at Faber and Faber to avoid small talk with colleagues as they left the office together in the evenings.Richard Salisbury:I think quite a lot of people do things like that. But I'm a good bit worse.NC:You have some remarkable illustrations of how much worse.RS:Before moving to Edinburgh (where I met David Wemyss, of course) I had a brief but enjoyable stay in Oxford, doing legal work for the city council there. One day, it was announced that my entire team, from senior executives down to administrative assistants, and one or two hangers-on, had been invited to Westminster for an "exchange of ideas" with civil servants there who were interested in a project I'd set up—to do with parking charges, of all things! Anyway, the plan was to go through to London by luxury coach as a day trip, but I could only think of the fragmented conversation on the journey—especially the conducting of conversations looking over my shoulder or half-standing up, or perhaps getting stuck for too long with one of my less-congenial colleagues. Carole found the answer: if I took the day before the visit as a holiday, and the day after too, I could be in London for the professional appointment but avoid the bus completely. I needed a reason, of course, but London being London I knew I'd easily find a concert that would sound like a convincing explanation for wanting to combine personal and professional objectives. Bruckner 8 did the trick. I needed a couple of nights in a hotel—here at the Bedford actually!—but it was well worth it. I'm never reluctant to have a day or two in Bloomsbury, having stayed here for six months, but the real motivation was the desperation to avoid my colleagues outside the carefully premeditated conversational tramlines I usually had in place. [End Page 211]NC:And that's just one of the many—quite different—ways in which you would characterize why you, like Eliot, would hide in a lavatory to avoid talking to people! But to an everyday, well-adjusted person, that would sound monstrous. Claustrophobically intropunitive—or narcissistic. There's even a case for suppressing the transcript of this interview, or destroying it altogether—but I don't think you'd like that! You assume completely that I'll bring it into existence. It'll be a middlebrow literary accomplishment—a literary coup that marshals the chaos of your experience... (shrink)

Many legal scholars well recognize that, in some instances, support for a law or policy may be primarily because of its expressive function, i.e. the statements it makes about underlying values. In these cases, the expressive content of a law or policy may actually overshadow its central purpose. Examples of this phenomenon, according to Cass Sunstein, include, for example, regulations against hate speech in the USA. He suggests that achieving the consequence (prohibiting hateful speech against certain groups) may (...) not be the real focus (central purpose) of the law. Rather, the real focus is on the social meaning of these regulations—that bigotry is unacceptable in a liberal society. In this way, a particular law or policy can operate on many levels—while aiming to achieve a particular objective or behavior, it can also be a valuable tool for achieving other important social goals through its expressive function. This article applies this insight to the realm of public health policy, with particular attention to the case of pandemic planning, and suggests that public health policy and its overall goals may be well-served by deliberate regard for, and appropriate utilization of, the expressive function.

In this paper we focus on the difficulty in judging what is called covert hate speech. We emphasize the need for a multidimensional framework when analysing covert hate speech in situ, and the need to consider the multifaceted dimension of such speech act to assess its performativity. To explain such need, we apply the test of the Rabat Plan of Action and adopt a pragmatic perspective to analyse a specific covert hate speech act, considering such (...) class='Hi'>speech act as both an expressive and potentially performative act. We focus on the prosecution of hate speech against a woman holding a poster during an anti-safe pass demonstration. Her poster inferred a link between conspiracy theory, the government strategy addressing the Covid pandemic and many other collectives, primarily the Jewish community. Our analysis of the sign adopts a radically context-dependent methodology combining a pragmatic approach and the Rabat Plan of Action test. We then contrast our analysis with the legal and media perspective on the issue. We conclude by suggesting the benefit of integrating pragmatic analysis with application of normative set of rules such as the Rabat Plan of Action test, even though the fluidity of meaning always poses a challenge to any authority tasked with judging such communicative events.

This paper is aimed at the problems of low accuracy, long recognition time, and low recognition efficiency in English speech recognition. In order to improve the accuracy and efficiency of English speech recognition, an improved ant colony algorithm is used to deal with the dynamic time planning problem. The core is to adopt an adaptive volatilization coefficient and dynamic pheromone update strategy for the basic ant colony algorithm. Using new state transition rules and optimal ant parameter selection (...) and other improved methods, the best path can be found in a shorter time and the execution efficiency can be improved. Simulation experiments tested the recognition rates of traditional ant colony algorithm and improved ant colony algorithm. The results show that the global search ability and accuracy of improved ant colony algorithm are better than traditional algorithms, which can effectively improve the efficiency of English speech recognition system.

During face‐to‐face conversation, transitions between speaker turns are incredibly fast. These fast turn exchanges seem to involve next speakers predicting upcoming semantic information, such that next turn planning can begin before a current turn is complete. Given that face‐to‐face conversation also involves the use of communicative bodily signals, an important question is how bodily signals such as co‐speech hand gestures play into these processes of prediction and fast responding. In this corpus study, we found that hand gestures that (...) depict or refer to semantic information started before the corresponding information in speech, which held both for the onset of the gesture as a whole, as well as the onset of the stroke (the most meaningful part of the gesture). This early timing potentially allows listeners to use the gestural information to predict the corresponding semantic information to be conveyed in speech. Moreover, we provided further evidence that questions with gestures got faster responses than questions without gestures. However, we found no evidence for the idea that how much a gesture precedes its lexical affiliate (i.e., its predictive potential) relates to how fast responses were given. The findings presented here highlight the importance of the temporal relation between speech and gesture and help to illuminate the potential mechanisms underpinning multimodal language processing during face‐to‐face conversation.

The final speech given by Samuel to mark the passing from a theocratic to a monarchical regime is distinguished by the strategy of learning from their own history. The leader uses historical elements to determine the community to obey Yahweh as a part of an educational strategy whereby the leader uses history for pedagogical purposes. The mentioned events are subjective in nature and reflect the re-validation of Samuel as leader, the belief that Saul had become a part of the (...) divine plan of government, and it highlights the sins of the people showing the decisive contribution of Yahweh to the progress of the community up until that moment.

The article presents the results of the analysis of international legal regulation of the protection of freedom of speech, the right to freedom of expression within the UN and the Council of Europe. A comparative analysis of the definition of the right to express views and beliefs in various international legal acts was made. The case law of the European Court of Human Rights in cases related to the exercise of the right to express one's views and beliefs on (...) the Internet was considered. The analysis of the legislation of foreign countries regulating the right to express views and beliefs online was carried out. The materials of the article are of practical value for scientists and practitioners dealing with the issues of legal regulation of freedom of speech, the right to express views and beliefs, for forecasting and planning scientific research, improving legislation, for higher education teachers in educational activities, as well as for all interested persons.

Constraints on the types of speech errors observed can be accounted for by a frame/content distinction, but connectionist modeling shows that they do not require this distinction. The constraints may arise instead from the statistical properties of our language, in particular, the sequential biases observed in the vocabulary. Nevertheless, there might still be a role for the frame/content distinction in syntactic planning.

This article deals with Calchas’ prophecy and Diomedes’ and Ulysses’ interventions during the mustering of the Greeks at Aulis in Statius’ Achilleid. It will be argued that Calchas and Ulysses embody two different approaches to the generic tensions of the new epic which Statius’ poem represents. Calchas, the old uates of the Homeric tradition, seems unable to fully understand the ‘poetics of illusion’ enacted by Thetis and Achilles in disguise, as is clear from his vision. His point of view is (...) skilfully complemented by Ulysses, who turns out to be the true uates, as well as the perfect leader for Achilles’ rescue. As the only figure who can face the fluid and ambiguous reality of the poem and its literary dynamics as well, Ulysses also stands as a poetic voice himself; through his speech, Statius reflects upon the tensions of his epic and the poetic effort needed to channel the narrative from the peaceful setting of Scyros to the martial horizon of Troy.
