We explored the differential impact of auditory information and written contextual information on the recognition of verbal irony in spontaneous speech. Based on relevance theory, we predicted that speakers would provide acoustic disambiguation cues when speaking in situations that lack other sources of information, such as a visual channel. We further predicted that listeners would use this information, in addition to context, when interpreting the utterances. People were presented with spontaneously produced ironic and nonironic utterances from radio talk (...) shows in written or auditory form, with or without written contextual information. When the utterances were read without written contextual information, all utterances were rated as equally ironic. But when they were heard as opposed to read, or when they were presented in irony-biasing contexts, originally ironic utterances were rated as more sarcastic than originally nonironic utterances. This evidence suggests both acoustic and contextual information are used when inferring ironic intent in spontaneous speech, and validates previous manipulations of intonation in studies of irony understanding.

We introduce a novel experimental paradigm for eliciting metaphoric expressions in spontaneous speech, under controlled conditions. Participants were presented with a pair of words on a PC monitor and were asked to provide a verbal response describing a conceptual relation between the stimuli. The proportion of metaphoric responses depended on the stimuli in a predictable manner. A large proportion of metaphoric responses was obtained for stimuli that were derived from existing metaphors. The chronometric study of metaphor production in (...) this paradigm produced 3 major findings: (a) a figurative-literal difference: responses that included metaphorical expressions showed greater reaction times (RTs) than responses with only literal expressions; (b) familiarity effect: responses that included more-familiar metaphorical expressions showed smaller RTs than responses that included less-familiar metaphorical expressions; (c) degree of metaphoricity effect: responses that included highly metaphorical expressions showed greater RTs than responses that included less metaphorical expressions. We discuss the processing implications of these results. (shrink)

Dementia, a prevalent disorder of the brain, has negative effects on individuals and society. This paper concerns using Spontaneous Speech Challenge of Interspeech 2020 to classify Alzheimer's dementia. We used VGGish, a deep, pretrained, Tensorflow model as an audio feature extractor, and Scikit-learn classifiers to detect signs of dementia in speech. Three classifiers were 59.1% accurate, which was 3% above the best-performing baseline models trained on the acoustic features used in the challenge. We also proposed DemCNN, a (...) new PyTorch raw waveform-based convolutional neural network model that was 63.6% accurate, 7% more accurate then the best-performing baseline linear discriminant analysis model. We discovered that audio transfer learning with a pretrained VGGish feature extractor performs better than the baseline approach using automatically extracted acoustic features. Our DepCNN exhibits good generalization capabilities. Both methods presented in this paper offer progress toward new, innovative, and more effective computer-based screening of dementia through spontaneous speech. (shrink)

Individuals typically produce auditory sequences, such as speech or music, at a consistent spontaneous rate or tempo. We addressed whether spontaneous rates would show patterns of convergence across the domains of music and language production when the same participants spoke sentences and performed melodic phrases on a piano. Although timing plays a critical role in both domains, different communicative and motor constraints apply in each case and so it is not clear whether music and speech would (...) display similar timing mechanisms. We report the results of two experiments in which adult participants produced sequences from memory at a comfortable spontaneous (uncued) rate. In Experiment 1, monolingual pianists in Buffalo, New York engaged in three production tasks: speaking sentences from memory, performing short melodies from memory, and tapping isochronously. In Experiment 2, English-French bilingual pianists in Montréal, Canada produced melodies on a piano as in Experiment 1, and spoke short rhythmically-structured phrases repeatedly. Both experiments led to the same pattern of results. Participants exhibited consistent spontaneous rates within each task. People who produced one spoken phrase rapidly were likely to produce another spoken phrase rapidly. This consistency across stimuli was also found for performance of different musical melodies. In general, spontaneous rates across speech and music tasks were not correlated, whereas rates of tapping and music were correlated. Speech rates (for syllables) were faster than music rates (for tones) and speech showed a smaller range of spontaneous rates across individuals than did music or tapping rates. Taken together, these results suggest that spontaneous rate reflects cumulative influences of endogenous rhythms (in consistent self-generated rates within domain), peripheral motor constraints (in finger movements across tapping and music), and communicative goals based on the cultural transmission of auditory information (slower rates for to-be-synchronized music than for speech).

Cognitive hearing science is mainly about the study of how cognitive factors contribute to speech comprehension, but cognitive factors also partake in speech processing to infer non-linguistic information from speech signals, such as the intentions of the talker and the speaker’s age. Here, we report two experiments on age estimation by “naïve” listeners. The aim was to study how speech rate influences estimation of speaker age by comparing the speakers’ natural speech rate with increased or (...) decreased speech rate. In Experiment 1, listeners were presented with audio samples of read speech from three different speaker age groups (young, middle aged, and old adults). They estimated the speakers as younger when speech rate was faster than normal and as older when speech rate was slower than normal. This speech rate effect was slightly greater in magnitude for older (60–65 years) speakers in comparison with younger (20–25 years) speakers, suggesting that speech rate may gain greater importance as a perceptual age cue with increased speaker age. This pattern was more pronounced in Experiment 2, in which listeners estimated age from spontaneous speech. Faster speech rate was associated with lower age estimates, but only for older and middle aged (40–45 years) speakers. Taken together, speakers of all age groups were estimated as older when speech rate decreased, except for the youngest speakers in Experiment 2. The absence of a linear speech rate effect in estimates of younger speakers, for spontaneous speech, implies that listeners use different age estimation strategies or cues (possibly vocabulary) depending on the age of the speaker and the spontaneity of the speech. Potential implications for forensic investigations and other applied domains are discussed. (shrink)

The linguistic complexity of words has largely been studied on the behavioral level and in experimental settings. Only little is known about the neural processes underlying it in uninstructed, spontaneous conversations. We built up a multimodal neurolinguistic corpus composed of synchronized audio, video, and electrocorticographic (ECoG) recordings from the fronto-temporo-parietal cortex to address this phenomenon based on uninstructed, spontaneous speech production. We performed extensive linguistic annotations of the language material and calculated word complexity using several numeric parameters. (...) We orthogonalized the parameters with the help of a linear regression model. Then, we correlated the spectral components of neural activity with the individual linguistic parameters and with the residuals of the linear regression model, and compared the results. The proportional relation between the number of consonants and vowels, which was the most informative parameter with regard to the neural representation of word complexity, showed effects in two areas: the frontal one was at the junction of the premotor cortex, the prefrontal cortex, and Brodmann area 44. The postcentral one lay directly above the lateral sulcus and comprised the ventral central sulcus, the parietal operculum and the adjacent inferior parietal cortex. Beyond the physiological findings summarized here, our methods may be useful for those interested in ways of studying neural effects related to natural language production and in surmounting the intrinsic problem of collinearity between multiple features of spontaneously spoken material.

Hidden Markov models (HMMs) have been successful for modelling the dynamics of carefully dictated speech, but their performance degrades severely when used to model conversational speech. Since speech is produced by a system of loosely coupled articulators, stochastic models explicitly representing this parallelism may have advantages for automatic speech recognition (ASR), particularly when trying to model the phonological effects inherent in casual spontaneous speech. This paper presents a preliminary feasibility study of one such model (...) class: loosely coupled HMMs. Exact model estimation and decoding is potentially expensive, so possible approximate algorithms are also discussed. Comparison of one particular loosely coupled model on an isolated word task suggests loosely coupled HMMs merit further investigation. An approximate algorithm giving performance which is almost always statistically indistinguishable from the exact algorithm is also identified, making more extensive research computationally feasible.

This study provides new longitudinal evidence on two major types of gesture–speech combination that play different roles in children’s early language. We analysed the spontaneous production of 10 Italian children observed monthly from 10–12 to 23–25 months of age. We evaluated the extent to which the developmental trends observed in children’s early gesture–word and word–word productions can predict subsequent verbal abilities. The results indicate that “complementary” and “supplementary” gesture–speech combinations predict subsequent language development in a different manner: (...) While the onset of “supplementary” combinations predicts the onset of two-word combinations, the use of “complementary” combinations at 12 and 18 months predicts the vocabulary and the ability to produce more words utterances at 2 years of age. Moreover, the results suggest that both “complementary” and “supplementary” crossmodal combinations are good predictive indexes of early verbal skills during the second year of age. (shrink)

The study of conversational humor has received relatively little empirical attention with almost no examinations of the role of vocal signals in spontaneous humor production. Here we report an analysis of spontaneous humorous speech in a rural Brazilian collective farm. The sample was collected over the course of ethnographic fieldwork in northeastern Brazil, and is drawn specifically from the monthly communal business meetings conducted in Portuguese. Our analyses focused on humorous utterances identified by the subsequent presence of (...) laughter. Acoustic features of these utterances were compared to non-humorous utterances by the same speakers of similar length and immediately preceding them to look for prosodic contrasts. This corpus provided a unique opportunity for examining the way people mark their humorous productions in a non-humorous environment. Contrary to the notion that speakers must mark their production of humor in order to facilitate audience understanding, no significant marking of a joking “frame” was detected across a range of acoustic dimensions. The only consistent difference — that the set-up and punch line segments were louder than baseline speech before it — does not well support a marking hypothesis and more likely reflects speaker adjustments to the acoustic conditions of the meeting hall. We present these data from the perspective of the encryption theory of humor that predicts speakers will not generally mark spontaneous, conversational humor in most contexts. (shrink)

Ce travail sur la réduction segmentale (c.-à-d. la suppression ou réduction temporelle de segments) en français spontané nous a permis de proposer une méthode de recherche pour les études en linguistique, ainsi que d’apporter des connaissances sur la propension à la réduction des segments à l’oral. Cette méthode, appelée méthode ascendante, nous permet de travailler sans hypothèse spécifique sur la réduction. Les résultats suggèrent que les liquides, les glides et la fricative voisée /v/ sont plus facilement réduites que les autres (...) consonnes et que les voyelles nasales résistent mieux à la réduction que les voyelles orales. Parmi les voyelles orales, les voyelles orales arrondies ont tendance à être plus souvent réduites que les autres voyelles orales. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Unmastering Speech:Irony in Plato's PhaedrusMatthew S. Linck"So, my shall suffer what it deserves."—Phaedrus 242a1It is tempting, after one has reflected closely on the words and deeds of the Phaedrus, to read the dialogue as if Socrates had the whole conversation worked out from the first words. The art of Plato is such that the intricate cohesion of word and action reveals itself through many layers. Plato writes; and (...) as a writer he has the time and the means (written letters) to compose. But what is Socrates doing? He does not have the leisure to compose "over a long period of time" (228a). He is responding to particular individuals, in particular circumstances, in the moment. He is thinking on his feet. One might claim that this is actually the first deficiency of the dialogues, that they are artificial and unrealistic in this way. If the written text reveals itself as finely crafted in the subtlety of its inner connections, how seriously can we take the apparent spontaneity of the spoken discourse? My suggestion would be that we take this not as a fault of the dialogues, but rather as the first instance of Plato's irony. This may be Plato's supreme irony—the evocation of truth through artificiality.But that is already going too fast. I want to begin by looking at the words and deeds of Socrates and Phaedrus, without considering yet what Plato might be doing as the author of the dialogue. My first interpretive principle will be to take the drama at face value, as naturalistic, temporal, and even commonplace—two friends go for a walk in the countryside to listen to speeches.Immediately, however, the commonness is disrupted. The city, the commonwealth, is left behind. This is certainly uncommon for Socrates, who never leaves the city walls.2 Furthermore, the language of the text indicates a thematization of, out-of-placeness, strangeness. Rather than being accused of already violating my one hermeneutical principle, it should be noted that this indication of strangeness comes through the words [End Page 264] and deeds of the characters, not through a retrospective recovery of the dialogue as a whole. From the beginning the reader encounters a tension between the commonplace and the unusual.3Nevertheless, the impetus to move outside of the city is commonplace enough. Phaedrus has a speech that Socrates wants to hear. Before Socrates is told what this speech is about, he indicates that nothing would please him more than "hearing how you [Phaedrus] and Lysias passed the time" (227b). After Phaedrus, in his excitement, gives away the topic of the speech—"an attempted seduction of a handsome boy—but not by a lover!" (227c)—Socrates seems even more eager to hear the speech. Does Socrates already see what is to come? Is he merely excited to hear a speech, or is he excited about challenging the beautiful Phaedrus' excitement about a speech that defends an unworthy principle—"that one should gratify the one who does not love rather than the one who does" (227c)?After leaving the city and finding a comfortable place for their speech, for, Phaedrus reads his copy of Lysias' speech for Socrates. The gist of Lysias' speech, as Phaedrus has already announced, is that a young lover should associate himself with, and gratify, a non-lover rather than one who is in love. One central theme of the speech, which will be important for thinking about irony, is that of self-mastery. The recurring motif in Lysias' speech is that the lover is not in control of himself, while the non-lover is. Therefore (the non-lover argues) associating with a lover is unpredictable, and will most likely result in harm to the beloved. The non-lover claims that his self-control will prevent and preclude unforeseen harm. This slippage, from self-mastery to mastery of the situation, is decisive. We would be wrong to interpret Socrates' two speeches as wholesale rejections of everything in Lysias' speech. Socrates cannot reject self-control outright. His consistent concern with rules out simply espousing lack of control. Yet the measuredness of Socratic practice does not entail the... (shrink)

Gestures—hand movements that accompany speech and express ideas—can help children learn how to solve problems, flexibly generalize learning to novel problem‐solving contexts, and retain what they have learned. But does it matter who is doing the gesturing? We know that producing gesture leads to better comprehension of a message than watching someone else produce gesture. But we do not know how producing versus observing gesture impacts deeper learning outcomes such as generalization and retention across time. Moreover, not all children (...) benefit equally from gesture instruction, suggesting that there are individual differences that may play a role in who learns from gesture. Here, we consider two factors that might impact whether gesture leads to learning, generalization, and retention after mathematical instruction: (1) whether children see gesture or do gesture and (2) whether a child spontaneously gestures before instruction when explaining their problem‐solving reasoning. For children who spontaneously gestured before instruction, both doing and seeing gesture led to better generalization and retention of the knowledge gained than a comparison manipulative action. For children who did not spontaneously gesture before instruction, doing gesture was less effective than the comparison action for learning, generalization, and retention. Importantly, this learning deficit was specific to gesture, as these children did benefit from doing the comparison manipulative action. Our findings are the first evidence that a child's use of a particular representational format for communication (gesture) directly predicts that child's propensity to learn from using the same representational format.

Understanding spoken language involves far more than decoding a linear sequence of phonetic elements. In view of the inherent variability of the acoustic signal in spontaneous speech, it is not entirely clear that the sort of representation derived from locus equations is sufficient to account for the robustness of spoken language understanding under real-world conditions. An alternative representation, based on the low-frequency modulation spectrum, provides a more plausible neural foundation for spoken language processing.

We welcome Cho and Wu’s suggestion that the study of auditory verbal hallucinations could be improved by contrasting and testing more explanatory models. However, we have some worries both about their criticisms of inner speech-based self-monitoring models and whether their proposed spontaneous activation model is explanatory.

Adults and children spontaneously produce gestures while they speak, and such gestures appear to support and expand on the information communicated by the verbal channel. Little research, however, has been carried out to examine the role played by gesture in the listener's representation of accumulating information. Do listeners attend to the gestures that accompany narrative speech? In what kinds of relationships between gesture and speech do listeners attend to the gestural channel? If listeners do attend to information received (...) in gesture, how is this information represented— is it 'tagged' as originating in the gestural channel? In this article research is described that addresses these questions. Results show that listeners do attend to information conveyed in gesture, when that information supplements or even contradicts the information conveyed by speech. And information received via gesture is available for retelling in speech. These results are taken to demonstrate that gesture is not taken by the listener to be epiphenomenal to the act of speaking, or a simple manual translation of speech. But they also suggest that the information conveyed in a discourse may be represented in a manner that is neither gesture nor language, although accessible to both channels. (shrink)

From the first months of life, human infants produce “protophones,” speech-like, non-cry sounds, presumed absent, or only minimally present in other apes. But there have been no direct quantitative comparisons to support this presumption. In addition, by 2 months, human infants show sustained face-to-face interaction using protophones, a pattern thought also absent or very limited in other apes, but again, without quantitative comparison. Such comparison should provide evidence relevant to determining foundations of language, since substantially flexible vocalization, the inclination (...) to explore vocalization, and the ability to interact socially by means of vocalization are foundations for language. Here we quantitatively compare data on vocalization rates in three captive bonobo (Pan paniscus) mother–infant pairs with various sources of data from our laboratories on human infant vocalization. Both humans and bonobos produced distress sounds (cries/screams) and laughter. The bonobo infants also produced sounds that were neither screams nor laughs and that showed acoustic similarities to the human protophones. These protophone-like sounds confirm that bonobo infants share with humans the capacity to produce vocalizations that appear foundational for language. Still, there were dramatic differences between the species in both quantity and function of the protophone and protophone-like sounds. The bonobo protophone-like sounds were far less frequent than the human protophones, and the human protophones were far less likely to be interpreted as complaints and more likely as vocal play. Moreover, we found extensive vocal interaction between human infants and mothers, but no vocal interaction in the bonobo mother–infant pairs—while bonobo mothers were physically responsive to their infants, we observed no case of a bonobo mother vocalization directed to her infant. Our cross-species comparison focuses on low- and moderate-arousal circumstances because we reason the roots of language entail vocalization not triggered by excitement, for example, during fighting or intense play. Language appears to be founded in flexible vocalization, used to regulate comfortable social interaction, to share variable affective states at various levels of arousal, and to explore vocalization itself.

We investigate whether infant‐directed speech (IDS) could facilitate word form learning when compared to adult‐directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable inIDSthan inADS. At the phonological level, we find an effect in (...) the opposite direction: TheIDSlexicon contains more distinctive words (such as onomatopoeias) than theADScounterpart. Combining the acoustic and phonological metrics together in a global discriminability score reveals that the bigger separation of lexical categories in the phonological space does not compensate for the opposite effect observed at the acoustic level. As a result,IDSword forms are still globally less discriminable thanADSword forms, even though the effect is numerically small. We discuss the implication of these findings for the view that the functional role ofIDSis to improve language learnability. (shrink)

How did human vocalizations come to acquire meaning in the evolution of our species? Charles Darwin proposed that language and music originated from a common emotional signal system based on the imitation and modification of sounds in nature. This protolanguage is thought to have diverged into two separate systems, with speech prioritizing referential functionality and music prioritizing emotional functionality. However, there has never been an attempt to empirically evaluate the hypothesis that a single communication system can split into two (...) functionally distinct systems that are characterized by music- and languagelike properties. Here, we demonstrate that when referential and emotional functions are introduced into an artificial communication system, that system will diverge into vocalization forms with speech- and music-like properties, respectively. Participants heard novel vocalizations as part of a learning task. Half referred to physical entities and half functioned to communicate emotional states. Participants then reproduced each sound with the defined communicative intention in mind. Each recorded vocalization was used as the input for another participant in a serial reproduction paradigm, and this procedure was iterated to create 15 chains of five participants each. Referential vocalizations were rated as more speech-like, whereas emotional vocalizations were rated as more music-like, and this association was observed cross-culturally. In addition, a stable separation of the acoustic profiles of referential and emotional vocalizations emerged, with some attributes diverging immediately and others diverging gradually across iterations. The findings align with Darwin’s hypothesis and provide insight into the roles of biological and cultural evolution in the divergence of language and music. (shrink)

What is it for a speech act to be sincere? The most common answer amongst philosophers is that a speech act is sincere if and only if the speaker is in the state of mind that the speech act functions to express. However, a number of philosophers have advanced counterexamples purporting to demonstrate that having the expressed state of mind is neither necessary nor sufficient for speaking sincerely. One may nevertheless doubt whether these considerations refute the orthodox (...) conception. Instead, it may be argued, they expose other ways of elucidating sincerity in speech. “Sincerity in speech” is ambivalent between a number of different conceptions. Against this background this paper presents two alternative conceptions, viz., Sincerity as Spontaneity and Sincerity as Presenting Oneself as one takes Oneself to be and develops a third conception which we may call Sincerity as a Communicative Virtue. This conception emphasizes the speaker’s intention in communicating her attitudes and the need to be properly justified in saying what one does. (shrink)

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)

Infant-directed speech, the particular form of spontaneous language observed in interactions between parents and their infants, is a crucial aspect of the mother-infant interaction and an index of the attunement of maternal linguistic input to her infant communicative abilities and needs during dyadic interactions. The present study aimed to explore linguistic and pragmatic features of IDS during mother-infant interactions at 3-month of infant age. The effects of infant, maternal and dyadic factors on IDS were explored. Results evidenced few (...) differences between the groups on IDS linguistic characteristics. Moreover, observing the interaction of birth status and dyadic co-regulation, full-term mothers varied their IDS pragmatic features according to the quality of co-regulation while preterm mothers did not. Parenting stress was associated to specific linguistic IDS features independently from the birth status. Findings are discussed underling implications for the study of preterm dyads interactions and the importance to consider the interplay of several factors in affecting the quality of IDS. (shrink)

Several investigations have shown language impairments following electrode implantation surgery for Deep Brain Stimulation (DBS) in movement disorders. The impact of the actual stimulation, however, differs between DBS targets with further deterioration in formal language tests induced by thalamic DBS in contrast to subtle improvement observed in subthalamic DBS. Here, we studied speech samples from interviews with participants treated with DBS of the thalamic ventral intermediate nucleus (VIM) for essential tremor (ET), or the subthalamic nucleus (STN) for Parkinson’s disease (...) (PD), and healthy volunteers (eachn= 13). We analyzed word frequency and the use of open and closed class words. Active DBS increased word frequency in case of VIM, but not STN stimulation. Further, relative to controls, both DBS groups produced fewer open class words. Whereas VIM DBS further decreased the proportion of open class words, it was increased by STN DBS. Thus, VIM DBS favors the use of relatively common words in spontaneous language, compatible with the idea of lexical simplification under thalamic stimulation. The absence or even partial reversal of these effects in patients receiving STN DBS is of interest with respect to biolinguistic concepts suggesting dichotomous thalamic vs. basal ganglia roles in language processing.

Cette étude qualitative propose une modélisation multimodale des constructions subordonnées en conversation spontanée, à partir de leur action sur les cadres interprétatifs. Les subordonnées ont longtemps été décrites en linguistique comme des éléments dépendants qui complètent des éléments primaires.

Les subordonnées sont des pratiques interactionnelles qui offrent une (...) reconstruction interprétative du discours. Les différents types syntaxiques de subordonnées font référence à différents cadres interprétatifs dans l'expérience du locuteur. La sélection de ces différents cadres est exprimée par le nombre différent d'indices de frontière prosodiques et gestuels produits en co-occurrence avec chaque type syntaxique de subordonnée.

Language experience shapes the gradual maturation of speech production in both native and second languages. Structural aspects like the connectedness of spontaneous narratives reveal this maturation progress in L1 acquisition and, as it does not rely on semantics, it could also reveal structural pattern changes during L2 acquisition. The current study tested whether L2 lexical retrieval associated with vocabulary knowledge could impact the global connectedness of narratives during the initial stages of L2 acquisition. Specifically, the study evaluated the (...) relationship between graph structure and L2 learners’ oral production in the L2 and L1. Seventy-nine college-aged students who were native speakers of English and had received classroom instruction in either L2-Spanish or L2-Chinese participated in this study. Three tasks were used: semantic fluency, phonemic fluency and picture description. Measures were operationalized as the number of words per minute in the case of the semantic and phonemic fluency tasks. Graph analysis was carried out for the picture description task using the computational tool SpeechGraphs to calculate connectedness. Results revealed significant positive correlations between connectedness in the picture description task and measures of speech production in the phonemic and semantic fluency tasks. These correlations were only significant for the participants’ L2- Spanish and Chinese. Results indicate that producing low connectedness narratives in L2 may be a marker of the initial stages of L2 oral development. These findings are consistent with the pattern reported in the early stages of L1 literacy. Future studies should further explore the interactions between graph structure and second language production proficiency, including more advanced stages of L2 learning and considering the role of cognitive abilities in this process.

Adopting a modified Stroop task, the authors tested the hypothesis that processing systems brought to bear on comprehension of emotional speech are attuned primarily to word evaluation in a low-context culture and language (i.e., in English), but they are attuned primarily to vocal emotion in a high-context culture and language (i.e., in Japanese). Native Japanese (Studies 1 and 2) and English speakers (Study 3) made a judgement of either vocal emotion or word evaluation of an emotionally spoken evaluative word. (...) Word evaluations and vocal emotions were comparable in extremity in the two languages. In support of the hypothesis, an interference effect by competing word evaluation in the vocal emotion judgement was significantly stronger in English than in Japanese. In contrast, an interference effect by competing vocal emotion in the word evaluation judgement was stronger in Japanese than in English. Implications for the cultural grounding of communication, emotion, and cognition are discussed. (shrink)

Wittgenstein demystified the notion of 'observational self-knowledge'. He dislodged the long-standing conception that we have privileged access to our impressions, sensations and feelings through introspection, and more precisely eliminated knowing as the kind of awareness that normally characterizes our first-person present-tense psychological statements. He was not thereby questioning our awareness of our emotions or sensations, but debunking the notion that we come to that awareness via any epistemic route. This makes the spontaneous linguistic articulation of our sensations and impressions (...) nondescriptive. Not descriptions, but expressions that seem more akin to behaviour than to language. I suggest that Wittgenstein uncovered a new species of speech acts. Far from the prearranged consecration of words into performatives, utterances are deeds through their very spontaneity. This gives language a new aura: the aura of the reflex action. I argue, against Peter Hacker, that spontaneous utterances have the categorial status of deeds. This has no reductive consequences in that I do not suggest that one category is reduced to another, but that the boundary between them is porous. This explodes the myth of an explanatory gap between the traditionally distinct categories of saying (or thinking) and doing, or of mind and body. (shrink)

Alzheimer's Disease is a form of dementia that affects the memory, cognition, and motor skills of patients. Extensive research has been done to develop accessible, cost-effective, and non-invasive techniques for the automatic detection of AD. Previous research has shown that speech can be used to distinguish between healthy patients and afflicted patients. In this paper, the ADReSS dataset, a dataset balanced by gender and age, was used to automatically classify AD from spontaneous speech. The performance of five (...) classifiers, as well as a convolutional neural network and long short-term memory network, was compared when trained on audio features and text features. The same audio and text features were used to train five regression models to predict the Mini-Mental State Examination score for each patient, a score that has a maximum value of 30. The top-performing classification models were the support vector machine and random forest classifiers trained on BERT embeddings, which both achieved an accuracy of 85.4% on the test set. The best-performing regression model was the gradient boosting regression model trained on BERT embeddings and CLAN features, which had a root mean squared error of 4.56 on the test set. The performance on both tasks illustrates the feasibility of using speech to classify AD and predict neuropsychological scores. (shrink)

The article addresses Raimond Gaita's attempt to construe the ethical in terms of a notion of speech that is tied to presence (each of us, he holds, is called to become someone ‘authentically present in speech and deed’ (Gaita 1991, p. 145)), a notion through which he articulates a sense both of human uniqueness – speech demands that one find one's own words – and of human fellowship: to find one's words is to achieve the depth that (...) enables one to be taken seriously by others. The article argues, however, that the notion of speech is caught in a double bind; for it requires a spontaneity that is incompatible with the self‐presence that it also requires. In a way that Gaita cannot acknowledge, goodness is beyond speech. (shrink)

Vygotsky (1997) coined the term speech-drawing to describe what he saw as the most significant moment in intellectual development, the moment when two psychological tools intersect each other.

Specifically, this paper will examine children’s drawings of make-believe houses and the private speech, or spontaneous self-directed speech, children produccd while drawing. These instances of speech-drawing will be utilized to illuminate critical (...) and creative thinking from a Vygotskian perspective. The future use of speech-drawing, as a promising methodological tool to study children’s thought processes, will also be presented and discussed. (shrink)

Many philosophers and psychologists have sought to explain experiences of auditory verbal hallucinations and “inserted thoughts” in schizophrenia in terms of a failure on the part of patients to appropriately monitor their own inner speech. These self-monitoring accounts have recently been challenged by some who argue that AVHs are better explained in terms of the spontaneous activation of auditory-verbal representations. This paper defends two kinds of self-monitoring approach against the spontaneous activation account. The defense requires first making (...) some important clarifications concerning what is at issue in the dispute between the two forms of theory. A popular but problematic self-monitoring theory is then contrasted with two more plausible conceptions of what the relevant self-monitoring deficits involve. The first appeals to deficits in the neural mechanisms that normally filter or attenuate sensory signals that are the result of one’s own actions. The second, less familiar, form of self-monitoring approach draws an important analogy between Wernicke’s aphasia and AVHs in schizophrenia. This style of self-monitoring theory pursues possible connections among AVHs, inserted thoughts, and the disorganized speech characteristic formal thought disorder. (shrink)

Is inner speech an intentional action, something we do, or a reaction, something that happens to us? This paper will argue that it can be both, (although not at the same time). Some inner speech utterances are reactive: they are spontaneous, they require no effort, and we are not in control of their occurring. These inner speech utterances fail to meet the traditional criteria for qualifying as intentional actions. But some inner speech ut- terances are (...) intentional actions, performed deliberately, effortfully and with as much control as any other intentional action. When we deliberate, for example, inner speech utterances are the basic actions by which we bring about the non-basic action of deliberating. (shrink)
