Vocabulary size has been suggested as a useful measure of “verbal abilities” that correlates with speech recognition scores. Knowing more words is linked to better speech recognition. How vocabulary knowledge translates to general speech recognition mechanisms, how these mechanisms relate to offline speech recognition scores, and how they may be modulated by acoustical distortion or age, is less clear. Age-related differences in linguistic measures may predict age-related differences in speech recognition in noise performance. We hypothesized (...) that speech recognition performance can be predicted by the efficiency of lexical access, which refers to the speed with which a given word can be searched and accessed relative to the size of the mental lexicon. We tested speech recognition in a clinical German sentence-in-noise test at two signal-to-noise ratios (SNRs), in 22 younger (18–35 years) and 22 older (60–78 years) listeners with normal hearing. We also assessed receptive vocabulary, lexical access time, verbal working memory, and hearing thresholds as measures of individual differences. Age group, SNR level, vocabulary size, and lexical access time were significant predictors of individual speech recognition scores, but working memory and hearing threshold were not. Interestingly, longer accessing times were correlated with better speech recognition scores. Hierarchical regression models for each subset of age group and SNR showed very similar patterns: the combination of vocabulary size and lexical access time contributed most to speech recognition performance; only for the younger group at the better SNR (yielding about 85% correct speech recognition) did vocabulary size alone predict performance. Our data suggest that successful speech recognition in noise is mainly modulated by the efficiency of lexical access. This suggests that older adults’ poorer performance in the speech recognition task may have arisen from reduced efficiency in lexical access; with an average vocabulary size similar to that of younger adults, they were still slower in lexical access.

This study investigated whether age and/or differences in hearing sensitivity influence the perception of the emotion dimensions arousal (calm vs. aroused) and valence (positive vs. negative attitude) in conversational speech. To that end, this study specifically focused on the relationship between participants’ ratings of short affective utterances and the utterances’ acoustic parameters (pitch, intensity, and articulation rate) known to be associated with the emotion dimensions arousal and valence. Stimuli consisted of short utterances taken from a corpus of conversational (...) class='Hi'>speech. In two rating tasks, younger and older adults either rated arousal or valence using a 5-point scale. Mean intensity was found to be the main cue participants used in the arousal task (i.e., higher mean intensity cueing higher levels of arousal) while mean F 0 was the main cue in the valence task (i.e., higher mean F 0 being interpreted as more negative). Even though there were no overall age group differences in arousal or valence ratings, compared to younger adults, older adults responded less strongly to mean intensity differences cueing arousal and responded more strongly to differences in mean F 0 cueing valence. Individual hearing sensitivity among the older adults did not modify the use of mean intensity as an arousal cue. However, individual hearing sensitivity generally affected valence ratings and modified the use of mean F 0. We conclude that age differences in the interpretation of mean F 0 as a cue for valence are likely due to age-related hearing loss, whereas age differences in rating arousal do not seem to be driven by hearing sensitivity differences between age groups (as measured by pure-tone audiometry).

Debates about controversial comedy are rife in public discourse. However, despite a great interest in wider issues surrounding freedom of expression, political philosophers have had curiously little to say about comedy. This is a costly omission because in mainstream public debates, many of the worries about the potential harms of comedy are often confused or conflated, and both the defences of comedians to use controversial material and calls for censorship of such material are usually under-theorised. This paper takes a step (...) towards correcting this oversight by explaining the potential harms of comedy and identifying who should be held responsible for these harms. By transposing existing work on hate speech, three harms of comedy are diagnosed: that it can cause status harms, that it can silence speakers, and that it can motivate violence. Using linguistic theory and the philosophy of language, the paper argues that often, it is audience members and third parties who ought to be held morally responsible for these harms, and therefore, that comedians are not usually under moral duties to modify their comedic expression, even if it is harmful.

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

Unfortunately, many people today see the regulation of lies, disinformation, hate speech, and fake news as an infringement of free speech, at least when such speech is ‘political,’ despite the damage that such speech can do. But this very protective attitude toward speech rests on a mistaken understanding of the role of free speech in a liberal society. The right to free speech is based on the liberal value of freedom, and as such (...) can be no broader than freedom itself. And freedom has always been subject to reasonable limits in a liberal society. Indeed, while the principles of toleration and neutrality are often cited as supporting a broad interpretation of the right to free speech, they also tell us that certain limits apply to that right. We need not tolerate speech that encourages intolerance, and while government should be neutral between reasonable conceptions of the good, it need not be neutral between reasonable and unreasonable conceptions. These ideas form the framework of liberal society, and as I shall show, also provide a guide for understanding what kind of speech is protected in a liberal society and what it is not. (shrink)

This paper examines the surprisingly central role of sympathetic love within Margaret Cavendish’s philosophy. It shows that such love fulfils a range of metaphysical functions, and highlight an important shift in Cavendish’s account vis-a-vis earlier conceptions: sympathetic love is no longer given an emanative or mechanistic explanation, but is naturalized as an active emotion. It furthers investigate to what extent Cavendish’s account reveals a rift between the realm of nature and the realm of human sociability, and whether this rift really (...) prompts an inward turn, as some interpreters have suggested.

It seems trivial to identify sound sequences as music or speech, particularly when the sequences come from different sound sources, such as an orchestra and a human voice. Can we also easily distinguish these categories when the sequence comes from the same sound source? On the basis of which acoustic features? We investigated these questions by examining listeners’ classification of sound sequences performed by an instrument intertwining both speech and music: the dùndún talking drum. The dùndún is commonly (...) used in south-west Nigeria as a musical instrument but is also perfectly fit for linguistic usage in what has been described as speech surrogates in Africa. One hundred seven participants from diverse geographical locations (15 different mother tongues represented) took part in an online experiment. Fifty-one participants reported being familiar with the dùndún talking drum, 55% of those being speakers of Yorùbá. During the experiment, participants listened to 30 dùndún samples of about 7s long, performed either as music or Yorùbá speech surrogate (n= 15 each) by a professional musician, and were asked to classify each sample as music or speech-like. The classification task revealed the ability of the listeners to identify the samples as intended by the performer, particularly when they were familiar with the dùndún, though even unfamiliar participants performed above chance. A logistic regression predicting participants’ classification of the samples from several acoustic features confirmed the perceptual relevance of intensity, pitch, timbre, and timing measures and their interaction with listener familiarity. In all, this study provides empirical evidence supporting the discriminating role of acoustic features and the modulatory role of familiarity in teasing apart speech and music. (shrink)

This paper argues, first, that one can render Protagoras’s view on the teach ability of political virtue coherent by distinguishing between the affect required for achieving it and the capacity for developing these affect into fully fledged virtues. Second, the paper argues that by focusing on Books II - III of the Republic one might see an affinity between between Protagoras’s suggestion that virtuous citizens might give advice, without ruling it, in the affairs of the city and Plato’s conservative practical (...) political theory.

Slurs are words with a well-known tendency to conjure up painful memories and experiences in members of their target communities. Owing to this tendency, it’s widely agreed that one ought to exercise considerable care when even mentioning a slur, so as to avoid needlessly inflicting distressing associations on members of the relevant group. This paper argues that this tendency to evoke distressing associations is precisely what makes slurs impactful verbal weapons. According to the ballistic theory, slurs make such potent insults (...) because they enable their users to maliciously inflict noxious associations on members of their target groups. To motivate this theory, I demonstrate its ability to explain a number of facts about slurs’ offensiveness that pose formidable difficulties for competing theories of slurs. I argue that the ballistic theory not only explains why slurs make such explosively impactful terms of abuse, but also why: uses of slurs can provoke offense even when they aren’t interpreted as expressions of the speaker’s racist attitudes; and why mentions of slurs are inoffensive in some contexts, but in other contexts, warrant a level of offense every bit as severe as that warranted by weaponized uses. I conclude with a brief discussion of a practical application of the ballistic theory. I demonstrate that the theory has an important consequence for legislative efforts to regulate and punish weaponized uses of slurs. (shrink)

Emotive speech is a social act in which a speaker displays emotional signals with a specific intention; in the case of third-party complaints, this intention is to elicit empathy in the listener. The present study assessed how the emotivity of complaints was perceived in various conditions. Participants listened to short statements describing painful or neutral situations, spoken with a complaining or neutral prosody, and evaluated how complaining the speaker sounded. In addition to manipulating features of the message, social-affiliative factors (...) which could influence complaint perception were varied by adopting a cross-cultural design: participants were either Québécois or French and listened to utterances expressed by both cultural groups. The presence of a complaining tone of voice had the largest effect on participant evaluations, while the nature of statements had a significant, but smaller influence. Marginal effects of culture on explicit evaluation of complaints were found. A multiple mediation analysis suggested that mean fundamental frequency was the main prosodic signal that participants relied on to detect complaints, though most of the prosody effect could not be linearly explained by acoustic parameters. These results highlight a tacit agreement between speaker and listener: what characterizes a complaint is how it is said, more than what it is about or who produces it. More generally, the study emphasizes the central importance of prosody in expressive speech acts such as complaints, which are designed to strengthen social bonds and supportive responses in interactive behavior. This intentional and interpersonal aspect in the communication of emotions needs to be further considered in research on affect and communication. (shrink)

The paper presents two objections against Putnam’s Twin Earth argument, which was intended to secure semantic externalism. I first claim that Putnam’s reasoning rests on two assumptions and then try to show why these assumptions are contentious. The first objection is that, given what we know about science, it is unlikely that there are any natural-kind terms whose extension is codetermined by a small set of microstructures required by Putnam’s indexical account of extension determination. The second objection is that there (...) may not be a plausible concept of a speech community whose adoption would classify Oscar and Twin Oscar as members of different speech communities and, at the same time, render Oscar and Twin Oscar as being in the same psychological state. I contend that Putnam’s argument fails because both objections are justified. (shrink)

_From the president of Wesleyan University, a compassionate and provocative manifesto on the crises confronting higher education_ In this bracing book, Michael S. Roth stakes out a pragmatist path through the thicket of issues facing colleges today to carry out the mission of higher education. With great empathy, candor, subtlety, and insight, Roth offers a sane approach to the noisy debates surrounding affirmative action, political correctness, and free speech, urging us to envision college as a space in which students (...) are empowered to engage with criticism and with a variety of ideas. Countering the increasing cynical dismissal—from both liberals and conservatives—of the traditional core values of higher education, this book champions the merits of different diversities, including intellectual diversity, with a timely call for universities to embrace boldness, rigor, and practical idealism.

This paper offers a normative account of the speech act of explanation with understanding as its norm. The previous accounts of the speech act of explanation rely on the factive notion of understanding and maintain that proper explanations require knowledge. I argue, however, that such accounts are too demanding and do not reflect the everyday practice of explanation and the attribution of understanding. Instead, I argue that the non-factive, objectual attitude of understanding is sufficient for a proper explanation. (...) On the normative level, explanations are governed by an audience-centred norm, i.e., they are sensitive to the epistemic position of the audience. According to the proposed account, an explanation is a communicative act in which one puts the audience in a position to understand the explained phenomenon. This proposal fits into the recent wave of applications of the normative account and makes space for the pluralism of illocutionary acts. (shrink)

It is not easy to find a fair balance between inappropriate speech on the one hand and the appearance of constraint and inaccessibility on the other. Also judges must deal with this difficult task. They must take care not to endanger values that are protected to secure the functionality of justice. This article deals with questions of why and how judges can fulfil this task and what might happen if they fail to do so. The article argues in favour (...) of temperate speech using arguments from the fields of judicial ethics and normative ethics. It also offers examples of intemperate speech that might be dangerous to justice. Last but not least, the article mentions the relevance of judicial temperate speech for the concept of open justice thanks to which the judiciary might seek public confidence. (shrink)

Currently, the most used method to measure brain activity under a non-invasive procedure is the electroencephalogram (EEG). This is because of its high temporal resolution, ease of use, and safety. These signals can be used under a Brain Computer Interface (BCI) framework, which can be implemented to provide a new communication channel to people that are unable to speak due to motor disabilities or other neurological diseases. Nevertheless, EEG-based BCI systems have presented challenges to be implemented in real life situations (...) for imagined speech recognition due to the difficulty to interpret EEG signals because of their low signal-to-noise ratio (SNR). As consequence, in order to help the researcher make a wise decision when approaching this problem, we offer a review article that sums the main findings of the most relevant studies on this subject since 2009. This review focuses mainly on the pre-processing, feature extraction, and classification techniques used by several authors, as well as the target vocabulary. Furthermore, we propose ideas that may be useful for future work in order to achieve a practical application of EEG-based BCI systems toward imagined speech decoding. (shrink)

A number of studies have shown that phonetic peculiarities, especially at the coarticulation level, exist in the disfluent as well as in the perceptively fluent speech of people who stutter (PWS). However, results from fluent speech are disparate and not easily interpretable. Are the coarticulatory features a manifestation of the disorder, or rather a compensation for the disorder itself? Our purpose is to investigate the coarticulatory behavior in the fluent speech of PWS in the attempt to answer (...) the question on its symptomatic or adaptive nature. In order to achieve this, we have studied the speech of 21 adult PWS (10 French and 11 Italian) compared to that of 20 fluent adults (10 French and 10 Italian). The participants had to repeat simple CV syllables in short carrier sentences, where C = /b, d, g/ and V = /a, i, u/. Crucially, this repetition task was performed under a condition with normal auditory feedback (NAF) for both the groups, and under a fluency-enhancing condition (only for PWS) due to an altered auditory feedback (AAF). The degree of coarticulation was measured by means of the Locus Equations (LE). Under NAF conditions, the coarticulation degree observed in fluent PWS speech is lower than that of the PWNS, and, more importantly, in AAF condition, PWS coarticulation appears even weaker than in the NAF condition. The latter result allows to interpret the low degree of coarticulation found in fluent speech of PWS under NAF condition as a compensation for the disorder, based on the fact that coarticulation is weaker in fluency-enhancing conditions. Since a lower degree of coarticulation is associated to a greater separation between the places of articulation of the consonant and the vowel, these results are compatible with the hypothesis that larger articulatory movements could be responsible for the stabilization of the PWS speech motor system, increasing the kinesthetic feedback from the effector system. This interpretation shares with a number of relatively recent proposal the idea that stuttering derives from an impaired feedforward (open-loop) control system, which makes PWS rely more heavily on a feedback-based (closed loop) motor control strategy.

The paper discusses a solution to Kripke’s skeptical problem proposed by E.V. Borisov. It shows that this solution is based on the idea of “introspection2”, i.e. intuitive knowledge of meaning, which: a) is an essential part of a speech act, b) is given in our immediate experience and c) doesn’t form a source of empirical facts. The author of the paper admits the significance of the proposed idea for the discussion of the skeptical problem. Nevertheless, he argues that: 1) (...) as a point of the discussion the idea of introspection2 needs to be established more extensively; 2) this idea reinforces not a straight solution of the problem, but skeptical.

Speech recognition plays an important role in human–computer interaction. The higher the accuracy and efficiency of speech recognition are, the larger the improvement of human–computer interaction performance. This article briefly introduced the hidden Markov model -based English speech recognition algorithm and combined it with a back-propagation neural network to further improve the recognition accuracy and reduce the recognition time of English speech. Then, the BPNN-combined HMM algorithm was simulated and compared with the HMM algorithm and the (...) BPNN algorithm. The results showed that increasing the number of test samples increased the word error rate and recognition time of the three speech recognition algorithms, among which the word error rate and recognition time of the BPNN-combined HMM algorithm were the lowest. In conclusion, the BPNN-combined HMM can effectively recognize English speeches, which provides a valid reference for intelligent recognition of English speeches by computers. (shrink)

Should "hate speech" be made a criminal offense, or does the First Amendment oblige Americans to permit the use of epithets directed against a person's race, religion, ethnic origin, gender, or sexual preference?

Recent Plato scholarship has grown increasingly comfortable with the notion that Plato’s art of writing brings his readers into the dialogue, challenging them to respond to deliberate errors or lacunae in the text. Drawing inspiration from Stanley Fish’s seminal reading of Satan’s speeches in Paradise Lost, this paper considers the narrative of Timaeus as deliberately unreliable, and argues that the actively critical reader is “the missing fourth” with which the dialogue famously begins. By continuing Timaeus with Critias—a dialogue that ends (...) with a missing speech—Plato points to the kind of reader he expects: one who can answer Critias’ question : ὡς μὲν γὰρ οὐκ εὖ τὰ παρὰ σοῦ λεχθέντα εἴρηται, τίς ἂν ἐπιχειρήσειεν ἔμφρων λέγειν.

Reno v. ACLU, the 1997 landmark decision by the United States Supreme Court providing sweeping protection to speech on the Internet, is usually discussed in terms of familiar First Amendment issues. Little noticed in the decision is the significance of the ontological assumptions of the justices in their first visit to cyberspace. I analyze the apparent awareness of the Supreme Court of ontological issues and problems with their approaches. I also argue that their current ontological assumptions have left open (...) the door to future suppression of free speech as the technology progresses. Ontology is significant because zoning in the physical world has long been recognized as a way to segregate "adult" entertainment from minors. So far, at least, the justices seem to agree that such zoning is not possible in cyberspace, and therefore that adult zones for certain forms of expression are not possible. But this conclusion is far from settled. The degree of free speech on the Internet in the future will depend on whether or not our ontological understanding of cyberspace supports such zoning or renders it incoherent or impossible.

Certain approaches to the meaning of utterances primarily characterize speakers' communicative intentions as the only source of meaning of a speaker's utterance. I show that a strict version of this position is difficult to maintain because the meaning of an utterance is partially due to the intentional attitudes of the audience to an utterance, including their reaction to the social identity of a speaker. This can result in a negotiation over meaning that can take place if the speaker and audience (...) do not agree on the significance of the utterance. The view is motivated if one takes an ameliorative approach to meaning which acknowledges that theories of meaning are constrained by normative concerns related to meaning and communication. (shrink)
