    Past research has investigated how children use different sources of information such as social cues and word-learning heuristics to infer referential intents. The present research explored how children weigh and use some of these cues to make referential inferences. Specifically, we examined how switching between languages known (familiar) or unknown (unfamiliar) to a child would influence his or her choice of cue to interpret a novel label in a challenging disambiguation task, where a pointing cue was pitted against the mutual exclusivity (ME) principle. Forty-eight 3-and 4-years-old English-Mandarin bilingual children listened to a story told either in English only (No-Switch), English and Mandarin (Familiar-Switch), English and Japanese (Unfamiliar-Switch), or English and English-sounding nonsense sentences (Nonsense-Switch). They were then asked to select an object (from a pair of familiar and novel objects) after hearing a novel label paired with the speaker's point at the familiar object, e.g., "Can you give me the blicket?" Results showed that children in the Familiar-Switch condition were more willing to relax ME to follow the speaker's point to pick the familiar object than those in the Unfamiliar-Switch condition, who were more likely to pick the novel object. No significant differences were found between the other conditions. Further analyses revealed that children in the Unfamiliar-Switch condition looked at the speaker longer than children in the other conditions when the switch happened. Our findings suggest that children weigh speakers' referential cues and word-learning heuristics differently in different language contexts while taking into account their communicative history with the speaker. There are important implications for general education and other learning efforts, such as designing learning games so that the history of credibility with the user is maintained and how learning may be best scaffolded in a helpful and trusting environment.

    Does visual experience in judging intent to harm change our brain responses? And if it does, what are the mechanisms affected? We addressed these questions by studying the abilities of Closed Circuit Television (CCTV) operators, who must identify the presence of hostile intentions using only visual cues in complex scenes. We used functional magnetic resonance imaging to assess which brain processes are modulated by CCTV experience. To this end we scanned 15 CCTV operators and 15 age and gender matched novices while they watched CCTV videos of 16 sec, and asked them to report whether each clip would end in violence or not. We carried out four separate whole-brain analyses including 3 model-based analyses and one analysis of intersubject correlation to examine differences between the two groups. The three model analyses were based on 1) experimentally pre-defined clip activity labels of fight, confrontation, playful, and neutral behaviour, 2) participants' reports of violent outcomes during the scan, and 3) visual saliency within each clip, as pre-assessed using eye-tracking. The analyses identified greater activation in the right superior frontal gyrus for operators than novices when viewing playful behaviour, and reduced activity for operators in comparison with novices in the occipital and temporal regions, irrespective of the type of clips viewed. However, in the parahippocampal gyrus, all three model-based analyses consistently showed reduced activity for experienced CCTV operators. Activity in the anterior part of the parahippocampal gyrus (uncus) was found to increase with years of CCTV experience. The intersubject correlation analysis revealed a further effect of experience, with CCTV operators showing correlated activity in fewer brain regions (superior and middle temporal gyrus, inferior parietal lobule and the ventral striatum) than novices. Our results indicate that long visual experience in action observation, aimed to predict harmful behaviour

    This book focuses on use of voice as a biometric measure for personal authentication. In particular, "Speaker Recognition" covers two approaches in speaker authentication: speaker verification (SV) and verbal information verification (VIV). The SV approach attempts to verify a speaker’s identity based on his/her voice characteristics while the VIV approach validates a speaker’s identity through verification of the content of his/her utterance(s). SV and VIV can be combined for new applications. This is still a new research topic with significant potential applications. The book provides with a broad overview of the recent advances in speaker authentication while giving enough attention to advanced and useful algorithms and techniques. It also provides a step by step introduction to the current state of the speaker authentication technology, from the fundamental concepts to advanced algorithms. We will also present major design methodologies and share our experience in developing real and successful speake...

Yet these “new” structures and “new” processes did not prevent a major judicial appointment scandal in the province of Quebec in 2010, culminating in the formation of the Bastarache Committee to recommend changes. This paper summarizes the forty-year history of Canadian judicial appointment committees, identifies the major challenges that face those committees, and suggests the basic values toward which reforms to the appointment process might be directed. Depuis les années 1970, la nomination des juges de première instance au Canada a généralement mis à contribution un comité de professionnels indépendants, bien que la structure de ce comité et son rôle dans le processus de nomination aient varié d’une province à l’autre et évolué avec le temps. Ces « nouvelles » structures et « nouveaux » processus n’ont certes pas empêché l’éclatement du scandale sur la nomination des juges au Québec en 2010. Ce scandale a donné lieu à la formation de la Commission Bastarache qui avait notamment le mandat de recommander des changements. La présent document résume les quarante ans d’histoire des comités canadiens de nomination des juges, recense les principaux défis que ces comités doivent relever, et propose les valeurs fondamentales qui devraient inspirer les réformes du processus de nomination.

    Rhythmic gymnastics (RG) is an aesthetic event balancing between art and sport that also has a performance rating system (Code of Points) given by the International Gymnastics Federation. It is one of the sports in which competition results greatly depend on the judges' evaluation. In the current study, we explored the judges' performance in a five-gymnast ensemble routine. An expert-novice paradigm (10 international-level, 10 national-level, and 10 novice-level judges) was implemented under a fully simulated procedure of judgment in a five-gymnast ensemble routine of RG using two videos of routines performed by the Greek national team of RG. Simultaneous recordings of two-dimensional eye movements were taken during the judgment procedure to assess the percentage of time spent by each judge viewing the videos and fixation performance of each judge when an error in gymnast performance had occurred. All judge level groups had very modest performance of error recognition on gymnasts' routines, and the best international judges reported approximately 40% of true errors. Novice judges spent significantly more time viewing the videos compared with national and international judges and spent significantly more time fixating detected errors than the other two groups. National judges were the only group that made efficient use of fixation to detect errors. The fact that international-level judges outperformed both other groups, while not relying on visual fixation to detect errors, suggests that these experienced judges probably make use of other cognitive strategies, increasing their overall error detection efficiency, which was, however, still far below optimum.

It has many diverse application specially in the field of Surveillance , Immigrations at Airport , cyber security , transcription in multi-source of similar sound source, where it is difficult to assign transcription arbitrary. The most commonly speech parameterization used in speaker verification, K-mean, cepstral analysis, is detailed. Gaussian mixture modeling, which is the speaker modeling technique is then explained. Gaussian mixture models (GMM, perhaps the most robust machine learning algorithm has been introduced to examine and judge carefully speaker identification in text independent. The application or employment of Gaussian mixture models for monitoring & Analysing speaker identity is encouraged by the familiarity, awareness, or understanding gained through experience that Gaussian spectrum depict the characteristics of speaker's spectral conformational pattern and remarkable ability of GMM to construct capricious densities after that we illustrate 'Expectation maximization' an iterative algorithm which takes some arbitrary value in initial estimation and carry on the iterative process until the convergence of value is observed We have tried to obtained 85 ~ 95% of accuracy using speaker modeling of vector quantization and Gaussian Mixture model ,so by doing various number of experiments we are able to obtain 79 ~ 82% of identification rate using Vector quantization and 85 ~ 92.6% of identification rate using GMM modeling by Expectation maximization parameter estimation depending on variation of parameter.

    During communication, hearers try to infer the speaker's intentions to be able to understand what the speaker means. Nevertheless, whether (and how early) preschoolers track their interlocutors' mental states is still a matter of debate. Furthermore, there is disagreement about how children's ability to consult a speaker's belief in communicative contexts relates to their ability to track someone's belief in non-communicative contexts. Here, we study young children's ability to successfully acquire a word from a speaker with a false belief; we also assess the same children's success on a traditional false belief attribution task. We show that the ability to consult the epistemic state of a speaker during word learning develops between the ages of three and five. We also show that false belief understanding in word-learning contexts proceeds similarly to standard belief-attribution contexts when the tasks are equated. Our data offer evidence for the development of mind-reading abilities during language acquisition.

  3. What the speaker means: the recognition of speakers plans in discourse

    Energy Technology Data Exchange (ETDEWEB)

    Sidner, C.L.

    1983-01-01

    Human conversational participants depend upon the ability of their partners to recognize their intentions, so that those partners may respond appropriately. In such interactions, the speaker encodes his intentions about the hearer's response in a variety of sentence types. Instead of telling the hearer what to do, the speaker may just state his goals, and expect a response that meets these goals at least part way. This paper presents a new model for recognizing the speaker's intended meaning in determining a response. It shows that this recognition makes use of the speaker's plan, his beliefs about the domain and about the hearer's relevant capacities. 12 references.

    In Virginia v. Black (123 S.Ct. 1536, 2003), the Supreme Court ruled that the First Amendment did not bar statutes that prohibit cross burnings in which defendants acted with intention to intimidate others. Using a variety of symbols including cross burnings, swastikas, confederate flags, and skin fists, the current research tested how mock jurors used alternative actor intentions to judge culpability in symbolic hate speech cases. Only partially validating the Court's assumptions, participants rated guilt certainty highest when they believed the speakers conveyed direct threats, sometimes regardless of whether defendants intended to intimidate others. Further, results showed the level of perceived intimidation only partially mediated the relationship between type of fact pattern and guilt certainty ratings. While alternative intentions did produce different levels of intention to intimidate, path analysis showed that the participants' ratings of the defendant's intention to convey a direct threat influenced guilt certainty ratings in all cases. Perceived intimidation levels predicted culpability in only some of the cases and not for cross burning on private property.

    Full Text Available In many social realms, social media are employed by institutions to establish direct relations between ‘key agents’ and their clients or customers. In this article I explain why as yet the civil law judge cannot be expected to start using social networking sites to advance the transparency of the judicial decision-making process in a relatively open, form-free interaction with his or her ‘clients’. This explanation is grounded on the hybrid character of social networking sites. On the one hand, these sites are direct, interactive, informal, and personalized media; but on the other, they are public and basically permanent. Their direct, interactive, informal and personalized character is highly compatible with the multimodal, network-embedded, form-free self-representation of the modern judge in the courtroom. However, their public and permanent character manifests in the second performance of a judge, being held publicly and permanently accountable for what is decided. This performance is characterized by a unimodal, ‘punctualized’, formal self-representation. Referring to the work of legal sociologists as well as discourse scholars, it is underlined how much this public judicial self-representation is part of a persistent ritual that renders it incompatible with direct, interactive, informal and personalized communication. The hybrid character of social media does not allow judges to utilize them to act as key-agents: to open up the ‘backstage area’ to reveal the actual dynamics of the decision-making process, and to transparently connect the judicial performance in the courtroom session with the second performance when issuing a decision.

  15. A fundamental residue pitch perception bias for tone language speakers

    Science.gov (United States)

    Petitti, Elizabeth

    A complex tone composed of only higher-order harmonics typically elicits a pitch percept equivalent to the tone's missing fundamental frequency (f0). When judging the direction of residue pitch change between two such tones, however, listeners may have completely opposite perceptual experiences depending on whether they are biased to perceive changes based on the overall spectrum or the missing f0 (harmonic spacing). Individual differences in residue pitch change judgments are reliable and have been associated with musical experience and functional neuroanatomy. Tone languages put greater pitch processing demands on their speakers than non-tone languages, and we investigated whether these lifelong differences in linguistic pitch processing affect listeners' bias for residue pitch. We asked native tone language speakers and native English speakers to perform a pitch judgment task for two tones with missing fundamental frequencies. Given tone pairs with ambiguous pitch changes, listeners were asked to judge the direction of pitch change, where the direction of their response indicated whether they attended to the overall spectrum (exhibiting a spectral bias) or the missing f0 (exhibiting a fundamental bias). We found that tone language speakers are significantly more likely to perceive pitch changes based on the missing f0 than English speakers. These results suggest that tone-language speakers' privileged experience with linguistic pitch fundamentally tunes their basic auditory processing.

    What are the features that impersonators select to elicit a speaker's identity? We built a voice database of public figures (targets) and imitations produced by professional impersonators. They produced one imitation based on their memory of the target (caricature) and another one after listening to the target audio (replica). A set of naive participants then judged identity and similarity of pairs of voices. Identity was better evoked by the caricatures and replicas were perceived to be closer to the targets in terms of voice similarity. We used this data to map relevant acoustic dimensions for each task. Our results indicate that speaker identity is mainly associated with vocal tract features, while perception of voice similarity is related to vocal folds parameters. We therefore show the way in which acoustic caricatures emphasize identity features at the cost of loosing similarity, which allows drawing an analogy with caricatures in the visual space.

    Directory of Open Access Journals (Sweden)

    Maria Flávia Figueiredo

    2016-07-01

    Full Text Available The rhetoric is guided by three dimensions: logos, pathos and ethos. Logos is the speech itself, pathos are the passions that the speaker, through logos, awakens in his audience, and ethos is the image that the speaker creates of himself, also through logos, in front of an audience. The rhetorical genres are three: deliberative (which drives the audience or the judge to think about future events, characterizing them as convenient or harmful, judiciary (the audience thinks about past events in order to classify them as fair or unfair and epidictic (the audience will judge any fact occurred, or even the character of a person as beautiful or not. According to Figueiredo (2014 and based on Eggs (2005, we advocate that ethos is not a mark left by the speaker only in rhetorical genres, but in any textual genre, once the result of human production, the simplest choices in textual construction, are able to reproduce something that is closely linked to speaker, thus, demarcating hir/her ethos. To verify this assumption, we selected a display of a video of the comedian Danilo Gentili, which will be examined in the light of Rhetoric and Textual Linguistics. So, our objective is to find, in the stand-up comedy genre, marks left by the speaker in the speech that characterizes his/her ethos. The analysis results show that ethos, discursive genre and communicational purpose amalgamate in an indissoluble complex in which the success of one of them interdepends on how the other was built.

Such inconsistencies introduce ambiguity, which may render a speaker to be a less credible source of information. Two experiments examined whether children make credibility discriminations based on the consistency of speakers' affect cues. In Experiment 1, school-age children (7- to 8-year-olds) preferred to solicit information from consistent speakers (e.g. those who provided a negative statement with negative affect), over novel speakers, to a greater extent than they preferred to solicit information from inconsistent speakers (e.g. those who provided a negative statement with positive affect) over novel speakers. Preschoolers (4- to 5-year-olds) did not demonstrate this preference. Experiment 2 showed that school-age children's ratings of speakers were influenced by speakers' affect consistency when the attribute being judged was related to information acquisition (speakers' believability, "weird" speech), but not general characteristics (speakers' friendliness, likeability). Together, findings suggest that school-age children are sensitive to, and use, the congruency of affect cues to determine whether individuals are credible sources of information.

    The present study analyzes the phenomenon of intentional misinterpretation in verbal communication and its communicative functions.In human verbal communication,misunderstanding occurs when the hearer s understanding of the speaker s utterances is not identical with the speaker's intended one.However,in some cases,the hearer may intentionally choose the interpretation diverging from the speaker s intended meaning in order to achieve certain communicative effects.This kind of linguistic phenomenon can be called intentional misinterpretation,which performs various functions in human daily conversation.

    Glottal-pulse rate (GPR) and vocal-tract length (VTL) are both related to speaker size and sex-however, it is unclear how they interact to determine our perception of speaker size and sex. Experiments were designed to measure the relative contribution of GPR and VTL to judgements of speaker size and sex. Vowels were scaled to represent people with different GPRs and VTLs, including many well beyond the normal population values. In a single interval, two response rating paradigm, listeners judged the size (using a 7-point scale) and sex/age of the speaker (man, woman, boy, or girl) of these scaled vowels. Results from the size-rating experiments show that VTL has a much greater influence upon judgements of speaker size than GPR. Results from the sex-categorization experiments show that judgements of speaker sex are influenced about equally by GPR and VTL for vowels with normal GPR and VTL values. For abnormal combinations of GPR and VTL, where low GPRs are combined with short VTLs, VTL has more influence than GPR in sex judgements.

    2017-01-01

    This study investigated the acoustic basis of within-speaker, across-utterance variation in sentence intelligibility for 12 speakers with dysarthria secondary to Parkinson’s disease (PD). Acoustic measures were also obtained for 12 healthy controls for comparison to speakers with PD. Speakers read sentences using their typical speech style. Acoustic measures of speech rate, articulatory rate, fundamental frequency, sound pressure level and F2 interquartile range (F2 IQR) were obtained. A group of listeners judged sentence intelligibility using a computerized visual-analog scale. Relationships between judgments of intelligibility and acoustic measures were determined for individual speakers with PD. Relationships among acoustic measures were also quantified. Although considerable variability was noted, articulatory rate, fundamental frequency and F2 IQR were most frequently associated with within-speaker variation in sentence intelligibility. Results suggest that diversity among speakers with PD should be considered when interpreting results from group analyses. PMID:24874184

    The purposes of the study were to compare the temporal characteristics of nasalization between speakers with cleft palate with or without cleft lip and normal adult speakers and to investigate the relationship between acoustic temporal measures and perceived nasality. Fifteen speakers with cleft palate with or without cleft lip and 15 speakers without cleft palate aged 13 to 45 years participated in this study. Two listeners judged the degree of nasality in speakers with cleft palate with or without cleft lip. Two distinct acoustic energies derived from the mouth and nose were recorded simultaneously while speakers were producing the speech tasks /pimip/, /pamap/, and /pumup/. Absolute and proportional measures related to nasalization duration were obtained. Speakers with cleft palate with or without cleft lip exhibited more extensive acoustic nasalization in the time domain than did speakers without cleft palate with or without cleft lip. Speakers without cleft palate with or without cleft lip showed larger nasalization-duration ratios in the high vowel contexts than in the low vowel context. Speakers with cleft palate with or without cleft lip did not exhibit distinct differences in nasalization-duration ratios among the vowel contexts. The acoustic measurements reflecting temporal patterns of oral-nasal acoustic impedance were related to the perception of hypernasality. These results suggest that the speakers with cleft palate with or without cleft lip showed longer duration of acoustic nasalization than speakers without cleft palate with or without cleft lip. Temporal characteristics of acoustic nasalization grew longer as the degree of perceived hypernasality increased. The positive correlation between temporal measures of acoustic nasalization and degree of perceived nasality suggests that temporal measures of nasalization would provide supplementary diagnostic information in relation to the degree of hypernasality.

  10. Additive attacks on speaker recognition

    Farrokh Baroughi, Alireza; Craver, Scott

    2014-02-01

    Speaker recognition is used to identify a speaker's voice from among a group of known speakers. A common method of speaker recognition is a classification based on cepstral coefficients of the speaker's voice, using a Gaussian mixture model (GMM) to model each speaker. In this paper we try to fool a speaker recognition system using additive noise such that an intruder is recognized as a target user. Our attack uses a mixture selected from a target user's GMM model, inverting the cepstral transformation to produce noise samples. In our 5 speaker data base, we achieve an attack success rate of 50% with a noise signal at 10dB SNR, and 95% by increasing noise power to 0dB SNR. The importance of this attack is its simplicity and flexibility: it can be employed in real time with no processing of an attacker's voice, and little computation is needed at the moment of detection, allowing the attack to be performed by a small portable device. For any target user, knowing that user's model or voice sample is sufficient to compute the attack signal, and it is enough that the intruder plays it while he/she is uttering to be classiffed as the victim.

  14. Speech intelligibility of deaf speakers and distinctive feature usage.

    Mencke, E O; Ochsner, G J; Testut, E W

    1984-01-01

    Speech samples (41 CNC monosyllables) of 22 deaf children were analyzed using two distinctive-feature systems, one acoustic and one physiologic. Moderate to high correlations between intelligibility scores by listener judges vs correct feature usage were obtained for positive as well as negative features of both systems. Further, higher correlations between percent-correct feature usage scores vs listener intelligibility scores were observed for phonemes in the initial vs final position-in-work regardless of listener-judge experience, feature system, or presentation mode. These findings suggest that either acoustic or physiologic feature analysis can be employed in describing the articulation of deaf talkers. In general, either of these feature systems also predicts with fair to good accuracy the intelligibility of deaf speakers as judged by either experienced or inexperienced listeners. In view of the appreciably higher correlations obtained between feature use and intelligibility scores in initial compared to final position-in-word, however, caution should be exercised with either of the feature systems studied in predicting the intelligibility of a deaf speaker's final phoneme.

    Empirical research had initially shown that English listeners are able to identify the speakers' sexual orientation based on voice cues alone. However, the accuracy of this voice-based categorization, as well as its generalizability to other languages (language-dependency) and to non-native speakers (language-specificity), has been questioned recently. Consequently, we address these open issues in 5 experiments: First, we tested whether Italian and German listeners are able to correctly identify sexual orientation of same-language male speakers. Then, participants of both nationalities listened to voice samples and rated the sexual orientation of both Italian and German male speakers. We found that listeners were unable to identify the speakers' sexual orientation correctly. However, speakers were consistently categorized as either heterosexual or gay on the basis of how they sounded. Moreover, a similar pattern of results emerged when listeners judged the sexual orientation of speakers of their own and of the foreign language. Overall, this research suggests that voice-based categorization of sexual orientation reflects the listeners' expectations of how gay voices sound rather than being an accurate detector of the speakers' actual sexual identity. Results are discussed with regard to accuracy, acoustic features of voices, language dependency and language specificity.

    The present study examined English sentence stress produced by native Cantonese speakers who were speaking English as a second language (ESL). Cantonese ESL speakers' proficiency in English stress production as perceived by English-speaking listeners was also studied. Acoustical parameters associated with sentence stress including fundamental frequency (F0), vowel duration, and intensity were measured from the English sentences produced by 40 Cantonese ESL speakers. Data were compared with those obtained from 40 native speakers of American English. The speech samples were also judged by eight native listeners who were native speakers of American English for placement, degree, and naturalness of stress. Results showed that Cantonese ESL speakers were able to use F0, vowel duration, and intensity to differentiate sentence stress patterns. Yet, both female and male Cantonese ESL speakers exhibited consistently higher F0 in stressed words than English speakers. Overall, Cantonese ESL speakers were found to be proficient in using duration and intensity to signal sentence stress, in a way comparable with English speakers. In addition, F0 and intensity were found to correlate closely with perceptual judgement and the degree of stress with the naturalness of stress.

  8. Comprehending non-native speakers: theory and evidence for adjustment in manner of processing.

    Science.gov (United States)

    Lev-Ari, Shiri

    2014-01-01

    Non-native speakers have lower linguistic competence than native speakers, which renders their language less reliable in conveying their intentions. We suggest that expectations of lower competence lead listeners to adapt their manner of processing when they listen to non-native speakers. We propose that listeners use cognitive resources to adjust by increasing their reliance on top-down processes and extracting less information from the language of the non-native speaker. An eye-tracking study supports our proposal by showing that when following instructions by a non-native speaker, listeners make more contextually-induced interpretations. Those with relatively high working memory also increase their reliance on context to anticipate the speaker's upcoming reference, and are less likely to notice lexical errors in the non-native speech, indicating that they take less information from the speaker's language. These results contribute to our understanding of the flexibility in language processing and have implications for interactions between native and non-native speakers.

  9. Early testimonial learning: monitoring speech acts and speakers.

    Stephens, Elizabeth; Suarez, Sarah; Koenig, Melissa

    2015-01-01

    Testimony provides children with a rich source of knowledge about the world and the people in it. However, testimony is not guaranteed to be veridical, and speakers vary greatly in both knowledge and intent. In this chapter, we argue that children encounter two primary types of conflicts when learning from speakers: conflicts of knowledge and conflicts of interest. We review recent research on children's selective trust in testimony and propose two distinct mechanisms supporting early epistemic vigilance in response to the conflicts associated with speakers. The first section of the chapter focuses on the mechanism of coherence checking, which occurs during the process of message comprehension and facilitates children's comparison of information communicated through testimony to their prior knowledge, alerting them to inaccurate, inconsistent, irrational, and implausible messages. The second section focuses on source-monitoring processes. When children lack relevant prior knowledge with which to evaluate testimonial messages, they monitor speakers themselves for evidence of competence and morality, attending to cues such as confidence, consensus, access to information, prosocial and antisocial behavior, and group membership. © 2015 Elsevier Inc.

  11. Linguistic Creativity in Heritage Speakers

    Ekaterina Rakhilina

    2016-10-01

    Full Text Available This paper presents and analyzes lexical and syntactic evidence from heritage Russian as spoken by bilinguals dominant in American English. The data come from the Russian Learner Corpus, a new resource of spoken and written materials produced by heritage re-learners and L2 learners of Russian. The paper focuses on lexical phrase violations, which we divide further into transfer-based structures and novel creations, showing that the latter are used by heritage speakers, but generally not freely available to L2 learners. In constructing innovative expressions, heritage speakers follow general principles of compositionality. As a result, novel constructions are more semantically transparent than their correlates in the baseline or dominant language. We argue that such semantically transparent, compositional patterns are based on structures that are universally available across languages. However, L2 speakers resort to these universal strategies for creating novel phrases much less often than heritage speakers. In their linguistic creativity, heritage speakers’ utterances parallel those of L1 child learners rather than L2 speakers.

    Full Text Available This article discusses the intent, which is a fundamental element in the process of speech production and, in general, defines the purpose of the statements, as well as response. In most scientific disciplines intention has been investigated in the framework of such concepts as “intention.” It motivates dialogue, it gives meaning and value. The article highlights the main approaches to the concept of “intention”: philosophical, social, psychological. Within the framework of these approaches it is used the features of the functioning of intentions with the main specific characteristics of this concept, namely: 1 intention, 2 determination, 3 intentionality, 4 goal setting, 5 modality, 6 communicative failure, 7 manipulation, 8 rational choice. In philosophy, the term “intention” is seen as an intention, purpose, direction. In psychology, the term becomes a feature of the subjectivity of intentional behavior. It is also noted that the intention of understanding the psychological approach refers us to the concept of “intention”, the article highlighted two types of modality and the disclosure of their identity. In the field of social sciences study the term is inextricably linked with the concept as a rational choice, which in turn contributes to the selection of the strategies and tactics of behavior of the speaker in the communication process.

  14. Can you hear my age? Influences of speech rate and speech spontaneity on estimation of speaker age.

    Science.gov (United States)

    Skoog Waller, Sara; Eriksson, Mårten; Sörqvist, Patrik

    2015-01-01

    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.

    2006-12-01

    Sports magazines portrayal of female athletes over the past ten years, in terms of body size, age, and race was examined. Using the Contour Drawing Rating Scale (CDRS), estimated body size was obtained for cover models on a set of judged and non-judged sport magazines. The frequency with which the full bodies of models were depicted on the covers of these magazines was also investigated. Cover models on judged sport magazines were rated as significantly thinner than cover models on non-judged sport magazines. Judged sport magazines also displayed a higher number of full-body images than non-judged sport magazines. These findings suggest that individuals who read judged sport magazines are more likely to be exposed to thin media images than those reading non-judged sport magazines.

    Experiments investigating phonetic convergence in conversation often focus on interlocutors with similar phonetic inventories. Extending these experiments to those with dissimilar inventories requires understanding the capacity of speakers to imitate native and non-native phones. In the present study, we tested native Spanish and native English speakers to determine whether imitation of non-native tokens differs qualitatively from imitation of native tokens. Participants imitated a [ba]-[pa] continuum that varied in VOT from -60 ms (prevoiced, Spanish [b]) to +60 ms (long lag, English [p]) such that the continuum consisted of some tokens that were native to Spanish speakers and some that were native to English speakers. Analysis of the imitations showed two critical results. First, both groups of speakers demonstrated sensitivity to VOT differences in tokens that fell within their native regions of the VOT continuum (prevoiced region for Spanish and long lag region for English). Secondly, neither group of speakers demonstrated such sensitivity to VOT differences among tokens that fell in their non-native regions of the continuum. These results show that, even in an intentional imitation task, speakers cannot accurately imitate non-native tokens, but are clearly flexible in producing native tokens. Implications of these findings are discussed with reference to the constraints on convergence in interlocutors from different linguistic backgrounds.

    Italy is among the countries with the highest litigation rate and those with the highest duration of trials. This article shows that judge turnover contributes negatively to delays in Italian courts and outlines possible policies for improvement. In Italy, judges can voluntarily move from one...... office to another after three years of mandate, and the law prescribes their transfer after ten years to guarantee their independence. Flaws in the process managing the backlog of outbound judges and the existence of asynchrony between outbound and inbound transfers produce a chain of delays...... to the disposition of court cases. Using a novel dataset on Court of Appeal Districts in Italy (2008–2012), we provide evidence of a strong negative relation between high turnover rates and judicial performance. We find that marginal increases in judge turnover rates lead to a statistically significant decrease...

  19. The relationship between speech segment duration and vowel centralization in a group of older speakers.

    Fletcher, Annalise R; McAuliffe, Megan J; Lansford, Kaitlin L; Liss, Julie M

    2015-10-01

    This study examined the relationship between average vowel duration and spectral vowel quality across a group of 149 New Zealand English speakers aged 65 to 90 yr. The primary intent was to determine whether participants who had a natural tendency to speak slowly would also produce more spectrally distinct vowel segments. As a secondary aim, this study investigated whether advancing age exhibited a measurable effect on vowel quality and vowel durations within the group. In examining vowel quality, both flexible and static formant extraction points were compared. Two formant measurements, from selected [ɐ:], [ i:], and [ o:] vowels, were extracted from a standard passage and used to calculate two measurements of vowel space area (VSA) for each speaker. Average vowel duration was calculated from segments across the passage. The study found a statistically significant relationship between speakers' average vowel durations and VSA measurements indicating that, on average, speakers with slower speech rates produced more acoustically distinct speech segments. As expected, increases in average vowel duration were found with advancing age. However, speakers' formant values remained unchanged. It is suggested that the use of a habitually slower speaking rate may assist speakers in maintaining acoustically distinct vowels.

  20. Speaker independent acoustic-to-articulatory inversion

    Science.gov (United States)

    Ji, An

    Acoustic-to-articulatory inversion, the determination of articulatory parameters from acoustic signals, is a difficult but important problem for many speech processing applications, such as automatic speech recognition (ASR) and computer aided pronunciation training (CAPT). In recent years, several approaches have been successfully implemented for speaker dependent models with parallel acoustic and kinematic training data. However, in many practical applications inversion is needed for new speakers for whom no articulatory data is available. In order to address this problem, this dissertation introduces a novel speaker adaptation approach called Parallel Reference Speaker Weighting (PRSW), based on parallel acoustic and articulatory Hidden Markov Models (HMM). This approach uses a robust normalized articulatory space and palate referenced articulatory features combined with speaker-weighted adaptation to form an inversion mapping for new speakers that can accurately estimate articulatory trajectories. The proposed PRSW method is evaluated on the newly collected Marquette electromagnetic articulography -- Mandarin Accented English (EMA-MAE) corpus using 20 native English speakers. Cross-speaker inversion results show that given a good selection of reference speakers with consistent acoustic and articulatory patterns, the PRSW approach gives good speaker independent inversion performance even without kinematic training data.

    2017-05-17

    The purpose of this study was to examine the effect of severity of adductor spasmodic dysphonia (ADSD) and information about it on unfamiliar listeners' attitudes about speakers' personal characteristics, perceived vocal effort, and listener comfort on the basis of ratings of speech recordings. Fifteen women with ADSD and 5 controls provided speech samples. Forty-five unfamiliar listeners were randomized into 3 groups. Listeners in Group 1 received no information, listeners in Group 2 were told that some speakers had voice disorders or had no voice concerns, and listeners in Group 3 were provided diagnostic labels for each speaker and information about ADSD. Listeners then rated speech samples for attitudes, perceived vocal effort, and listener comfort. Speakers with ADSD were judged significantly worse than controls for attitudes related to "social desirability" and "intellect." There was no effect of severity on "personality" attributes. However, provision of a diagnostic label resulted in significantly more favorable personality ratings than when no label was provided. Perceived vocal effort and comfort became significantly more negative as ADSD severity increased. Finally, most listener ratings were unaffected by provision of additional information about ADSD. Listeners' perceptions about speakers with ADSD are difficult to change. Directions for counseling and public education need future study.

  2. Can you hear my age? Influences of speech rate and speech spontaneity on estimation of speaker age

    2015-07-01

    Full Text Available 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.

  6. Effects of cochannel speech on speaker identification

    2001-02-01

    Past studies have shown that speaker identification (SID) algorithms that utilized LPC cepstral feature and a vector quantization classifier can be sensitive to changes in environmental conditions. Many experiments have examined the effects of noise on the LPC cepstral feature. This work studies the effects of co-channel speech on a SID system. It has been found that co-channel interference will degrade the performance of a speaker identification system, but not significantly when compared to the effects of wideband noise on an SID system. Our results show that when the interfering speaker is modeled as one of the speakers within he training set, it has less of an effect on the performance of an SID system than when the interfering speaker is outside the set of modeled speakers.

    2013-10-01

    Full Text Available Training of German judges is part of general legal education which is the same for all regulated legal professions (judges, prosecutors, practising lawyers, lawyers in administration and private employment. This uniform qualification is acquired by passing two exams administered by the state, i.e. the Länder (not the Federation, the first exam after university studies and the second exam after state-organized practical training. The paper gives an overview of this system of legal education. Germany, as a rule, has career judges. Courts of first and second instance are administered by the Länder, therefore the Länder judicial administrations are also responsible for recruitment of young career judges. General criteria for appointment to any public office are laid down in the German constitution (Grundgesetz. Apart from this, selection proceedings differ in detail, although elaborate lists of criteria (employee profiles, competence profiles are widely used. Professional competence is judged with emphasis on exam results; personal competence and social competence are assessed in interviews with appointment commissions or staff managers of ministries of justice. The paper provides details of these proceedings and also gives the author’s personal experience with recruitment proceedings in the Court of Appeal district of Cologne.

  10. Analysis of Polish Vowels of Tracheoesophageal Speakers.

    2017-03-01

    The aim of this study was to determine the acoustical differences between normal and tracheoesophageal Polish speakers during Polish vowel production. Formant frequencies, namely, the first (F1) and second (F2) formant frequencies for 6 Polish vowels produced by 11 normal and 11 tracheoesophageal speakers, were analyzed using statistical analysis of variance and discriminant analysis. Spectral analysis showed that the F1 and F2 values of Polish vowels produced by tracheoesophageal speakers were significantly higher than those produced by normal speakers, with the exception of the F2 value of /i/ produced by tracheoesophageal speakers. Analysis of variance showed significant differences between speeches based on the F1 and F2 formant frequencies. Discriminant analysis based on the formant frequencies for F1 and F2 exhibited 73.33% of the mean classification score for tracheoesophageal speakers and 96.36% for normal speakers. Tracheoesophageal speakers exhibit higher F1 and F2 formant frequencies, with the exception of the F2 value for the vowel /i/ than normal speakers. Discriminant analysis showed that the classification process for TE speech exhibits lower accuracy due to the poorer classification of the vowels /i/, /u/, and /y/.

    杨继臣; 何俊; 李艳雄

    2012-01-01

    To improve the precision of speaker indexing, an algorithm of speaker indexing based on gender is proposed by modifying BIC which is often used in speaker change criterion and by using gender information. In the first step, penalty distance is proposed to judge whether a speaker changes, which settles the problem that it is needed to tune the penalty factor of the Bayesian information criterion(BIC) repeatedly by the speaker change criterion. In the second step, a gender model is used to judge every speaker's gender on the basis of speaker changes. In the third step, speaker model bootstrapping is used to identify a male speaker or a female speaker separately. The experimental results show that; it is unnecessary to tune the penalty factor compared to BIC and Fi is improved by 2% compared to DISTBIC by the speaker change detection; the speaker indexing accuracy is improved by 20. 93% and the accuracy on the number of speakers is improved by 3% by using the gender information in speaker identification.%为了提高说话人索引准确率,对说话人改变判决中常用的贝叶斯信息判决(BIC)进行改进和在说话人辨认中使用性别信息,提出了一种基于性别的说话人索引算法.首先使用惩罚距离公式对说话人改变进行检测,解决了在说话人改变判决中使用BIC需要不断调节惩罚因子的问题;其次在说话人改变检测的基础上,采用性别模型判断每个说话人的性别;最后把男性和女性说话人分别对待,使用说话人模型自举法对说话人进行辨认.实验结果表明:在说话人改变检测中,采用惩罚距离公式,和BIC相比不需要调整参数,和DISTBIC相比,在F1方面提高了2%;在说话人辨认方面,利用性别信息,说话人索引准确率(SIA)提高了20.93%,说话人数量准确率(SNA)方面提高了3%.

  12. Automatic Speaker Recognition Dependency on Both the Shape of Auditory Critical Bands and Speaker Discriminative MFCCs

    Directory of Open Access Journals (Sweden)

    JOKIC, I.

    2015-11-01

    Full Text Available Accuracy of an automatic speaker recognition system predominantly depends on speaker models and features that are used. An influence of the shape of auditory critical bands and a contribution of individual components of MFCC-based feature vectors are investigated in the paper and some experimental results are presented and showed their impact on the accuracy of automatic speaker recognition. The speaker-discrimination capability of the MFCCs was experimentally determined by comparing training and test models for the same speaker. The experiments are conducted with three speech databases and showed that 0th and 19th (the last one MFCCs are non speaker discriminative. The values of MFCCs are determined by the type of applied auditory critical band. The exponential auditory critical bands based on the lower part of exponential function have outperformed the speaker recognition accuracy of other auditory critical bands such as rectangular or triangular shape.

  13. The influence of visual speech information on the intelligibility of English consonants produced by non-native speakers.

    Kawase, Saya; Hannah, Beverly; Wang, Yue

    2014-09-01

    This study examines how visual speech information affects native judgments of the intelligibility of speech sounds produced by non-native (L2) speakers. Native Canadian English perceivers as judges perceived three English phonemic contrasts (/b-v, θ-s, l-ɹ/) produced by native Japanese speakers as well as native Canadian English speakers as controls. These stimuli were presented under audio-visual (AV, with speaker voice and face), audio-only (AO), and visual-only (VO) conditions. The results showed that, across conditions, the overall intelligibility of Japanese productions of the native (Japanese)-like phonemes (/b, s, l/) was significantly higher than the non-Japanese phonemes (/v, θ, ɹ/). In terms of visual effects, the more visually salient non-Japanese phonemes /v, θ/ were perceived as significantly more intelligible when presented in the AV compared to the AO condition, indicating enhanced intelligibility when visual speech information is available. However, the non-Japanese phoneme /ɹ/ was perceived as less intelligible in the AV compared to the AO condition. Further analysis revealed that, unlike the native English productions, the Japanese speakers produced /ɹ/ without visible lip-rounding, indicating that non-native speakers' incorrect articulatory configurations may decrease the degree of intelligibility. These results suggest that visual speech information may either positively or negatively affect L2 speech intelligibility.

In the first layer, penalty distance is proposed to judge whether speaker changes. In the second layer, speaker model bootstrapping is used to identify speaker first time. In the third layer, GMM Speaker Supervector(GMMSS) is used to identify speaker further in order to settle the problem of data mismatch in speaker model bootstrapping. Experimental results show that, it is no need to tune penalty factor compared to BIC and Fl can improve 2% compared to DISTBIC; speaker indexing accuracy can improve 8.95% and the accuracy on the number of speaker can improve 18.25% by using GMMSS in speaker identification.

  15. Apology Strategy in English By Native Speaker

    Directory of Open Access Journals (Sweden)

    Mezia Kemala Sari

    2016-05-01

    Full Text Available This research discussed apology strategies in English by native speaker. This descriptive study was presented within the framework of Pragmatics based on the forms of strategies due to the coding manual as found in CCSARP (Cross-Cultural Speech Acts Realization Project.The goals of this study were to describe the apology strategies in English by native speaker and identify the influencing factors of it. Data were collected through the use of the questionnaire in the form of Discourse Completion Test, which was distributed to 30 native speakers. Data were classified based on the degree of familiarity and the social distance between speaker and hearer and then the data of native will be separated and classified by the type of strategies in coding manual. The results of this study are the pattern of apology strategies of native speaker brief with the pattern that potentially occurs IFID plus Offer of repair plus Taking on responsibility. While Alerters, Explanation and Downgrading appear with less number of percentage. Then, the factors that influence the apology utterance by native speakers are the social situation, the degree of familiarity and degree of the offence which more complicated the mistake tend to produce the most complex utterances by the speaker.

  16. Quantity language speakers show enhanced subcortical processing.

    The complex auditory brainstem response (cABR) can reflect language-based plasticity in subcortical stages of auditory processing. It is sensitive to differences between language groups as well as stimulus properties, e.g. intensity or frequency. It is also sensitive to the synchronicity of the neural population stimulated by sound, which results in increased amplitude of wave V. Finnish is a full-fledged quantity language, in which word meaning is dependent upon duration of the vowels and consonants. Previous studies have shown that Finnish speakers have enhanced behavioural sound duration discrimination ability and larger cortical mismatch negativity (MMN) to duration change compared to German and French speakers. The next step is to find out whether these enhanced duration discrimination abilities of quantity language speakers originate at the brainstem level. Since German has a complementary quantity contrast which restricts the possible patterns of short and long vowels and consonants, the current experiment compared cABR between nonmusician Finnish and German native speakers using seven short complex stimuli. Finnish speakers had a larger cABR peak amplitude than German speakers, while the peak onset latency was only affected by stimulus intensity and spectral band. The results suggest that early cABR responses are better synchronised for Finns, which could underpin the enhanced duration sensitivity of quantity language speakers. Copyright © 2016 The Authors.

  18. Speaker Adaptation with Transformation Matrix Linear Interpolation

    Institute of Scientific and Technical Information of China (English)

    XU Xiang-hua; ZHU Jie

    2004-01-01

    A transformation matrix linear interpolation (TMLI) approach for speaker adaptation is proposed. TMLI uses the transformation matrixes produced by MLLR from selected training speakers and the testing speaker. With only 3 adaptation sentences, the performance shows a 12.12% word error rate reduction. As the number of adaptation sentences increases, the performance saturates quickly. To improve the behavior of TMLI for large amounts of adaptation data, the TMLI+MAP method which combines TMLI with MAP technique is proposed. Experimental results show TMLI+MAP achieved better recognition accuracy than MAP and MLLR+MAP for both small and large amounts of adaptation data.

    Fernandez-Villarino, Maria A.; Bobo-Arce, Marta; Sierra-Palmeiro, Elena

    2013-01-01

    The aim of this study was to analyze the practical skills of rhythmic gymnastics judges and to identify how their degree and experience influence the assessment of these skills. Sixty one rhythmic gymnastics judges participated in the study. A questionnaire was used for data collection. This tool was composed of 28 questions and divided into six categories: identification, experience, initial training, continuing education, skills and training needs. The results suggest that the most valued skills are those related to the sport’s technical parameters and the ability to adapt to any level of competition with self-confidence and self-assuredness. Significant differences were found regarding the variables for: the ability to communicate (p = 0.002) and for the ability to observe, identify and register performance (p = 0.005). The results showed that experience was not a decisive factor in assessing skills. This study thus presents evidence that rhythmic gymnastics judges must implement and optimise a set of skills that contribute to the effectiveness of the assessment process. These findings might help in the design of programs and training models that contribute to effective professional development. PMID:24511360

  1. Planning an Effective Speakers Outreach Program

    1996-01-01

    The National Aeronautics and Space Administration (NASA) and, in particular, the Marshall Space Flight Center (MSFC) have played pivotal roles in the advancement of space exploration and space-related science and discovery since the early 1960's. Many of the extraordinary accomplishments and advancements of NASA and MSFC have gone largely unheralded to the general public, though they often border on the miraculous. This lack of suitable and deserved announcement of these "miracles" seems to have occurred because NASA engineers and scientists are inclined to regard extraordinary accomplishment as a normal course of events. The goal in this project has been to determine an effective structure and mechanism for communicating to the general public the extent to which our investment in our US civilian space program, NASA, is, in fact, a very wise investment. The project has involved discerning important messages of truth which beg to be conveyed to the public. It also sought to identify MSFC personnel who are particularly effective as messengers or communicators. A third aspect of the project was to identify particular target audiences who would appreciate knowing the facts about their NASA investment. The intent is to incorporate the results into the formation of an effective, proactive MSFC speakers bureau. A corollary accomplishment for the summer was participation in the formation of an educational outreach program known as Nasa Ambassadors. Nasa Ambassadors are chosen from the participants in the various MSFC summer programs including: Summer Faculty Fellowship Program (SFFP), Science Teacher Enrichment Program (STEP), Community College Enrichment Program (CCEP), Joint Venture (JOVE) program, and the NASA Academy program. NASA Ambassadors agree to make pre-packaged NASA-related presentations to non-academic audiences in their home communities. The packaged presentations were created by a small cadre of participants from the 1996 MSFC summer programs, volunteering

    Three interactive tasks, increasing in the complexity of resource-directing reasoning demands on speaker/storyteller attribution of, and linguistic reference to, the thoughts and intentions of characters in narrative stimuli were performed by Japanese L1 speakers of English. Largely consistent with the claims of the Cognition Hypothesis, results…

  3. Two Distinct Moral Mechanisms for Ascribing and Denying Intentionality.

    Philosophers and legal scholars have long theorized about how intentionality serves as a critical input for morality and culpability, but the emerging field of experimental philosophy has revealed a puzzling asymmetry. People judge actions leading to negative consequences as being more intentional than those leading to positive ones. The implications of this asymmetry remain unclear because there is no consensus regarding the underlying mechanism. Based on converging behavioral and neural evidence, we demonstrate that there is no single underlying mechanism. Instead, two distinct mechanisms together generate the asymmetry. Emotion drives ascriptions of intentionality for negative consequences, while the consideration of statistical norms leads to the denial of intentionality for positive consequences. We employ this novel two-mechanism model to illustrate that morality can paradoxically shape judgments of intentionality. This is consequential for mens rea in legal practice and arguments in moral philosophy pertaining to terror bombing, abortion, and euthanasia among others.

    We investigate a state-of-the-art Speaker Diarization system regarding its behavior on meetings that are much shorter (from 500 seconds down to 100 seconds) than those typically analyzed in Speaker Diarization benchmarks. First, the problems inherent to this task are analyzed. Then, we propose an approach that consists of a novel initialization parameter estimation method for typical state-of-the-art diarization approaches. The estimation method balances the relationship between the optimal v...

  7. Overview of Native-speaker English Teacher Versus Non-native-speaker English Teacher

    2015-01-01

    As much more non-native-speaker English teachers teach alongside native-speaker English teachers, either in China or any other non-English-speaking country, research on the differences between native-speaker English teacher and non-na⁃tive-speaker English teacher is necessary. This paper offers an overview of such difference between the two groups of English teachers in terms of their strengths and weaknesses, teaching styles and approaches. The conclusion suggests that cooperation and communication be emphsised and that the two groups of teachers communicate more and exchange their ideas on how to teach the same group of students more effectively.

  8. Speakers' choice of frame in binary choice

    Directory of Open Access Journals (Sweden)

    Marc van Buiten

    2009-02-01

    Full Text Available A distinction is proposed between extit{recommending for} preferred choice options and extit{recommending against} non-preferred choice options. In binary choice, both recommendation modes are logically, though not psychologically, equivalent. We report empirical evidence showing that speakers recommending for preferred options predominantly select positive frames, which are less common when speakers recommend against non-preferred options. In addition, option attractiveness is shown to affect speakers' choice of frame, and adoption of recommendation mode. The results are interpreted in terms of three compatibility effects, (i extit{recommendation mode---valence framing compatibility}: speakers' preference for positive framing is enhanced under extit{recommending for} and diminished under extit{recommending against} instructions, (ii extit{option attractiveness---valence framing compatibility}: speakers' preference for positive framing is more pronounced for attractive than for unattractive options, and (iii extit{recommendation mode---option attractiveness compatibility}: speakers are more likely to adopt a extit{recommending for} approach for attractive than for unattractive binary choice pairs.

  9. Pitch Correlogram Clustering for Fast Speaker Identification

    Directory of Open Access Journals (Sweden)

    Nitin Jhanwar

    2004-12-01

    Full Text Available Gaussian mixture models (GMMs are commonly used in text-independent speaker identification systems. However, for large speaker databases, their high computational run-time limits their use in online or real-time speaker identification situations. Two-stage identification systems, in which the database is partitioned into clusters based on some proximity criteria and only a single-cluster GMM is run in every test, have been suggested in literature to speed up the identification process. However, most clustering algorithms used have shown limited success, apparently because the clustering and GMM feature spaces used are derived from similar speech characteristics. This paper presents a new clustering approach based on the concept of a pitch correlogram that captures frame-to-frame pitch variations of a speaker rather than short-time spectral characteristics like cepstral coefficient, spectral slopes, and so forth. The effectiveness of this two-stage identification process is demonstrated on the IVIE corpus of 110 speakers. The overall system achieves a run-time advantage of 500% as well as a 10% reduction of error in overall speaker identification.

  11. "Judges of the Velum" and "Judges of the Hippodrome" in Thessalonike (11th c.

    Directory of Open Access Journals (Sweden)

    Andreas GKOUTZIOUKOSTAS

    2010-09-01

    Full Text Available The present study focuses on judicial officers coming from Constantinople to Thessalonike in the 11th century. The judge of the theme of Thessalonike was in charge of trying cases in the region. From the second fifth of the 11th century, however, his jurisdiction was extended to the greater financial and judicial unit of Boleron, Strymon and Thessalonike as well. Lead seals and documents from the archives of the monasteries of Athos prove that many of the krites of Boleron, Strymon and Thessalonike had been previously krites of the velum and judges of the hippodrome who performed their duties in the capital and belonged to the ranks of the “small judges”. These judicial officers tried cases that were referred to them, while they could also function as assessors of the “great” or superior judges of Constantinople, i.e. the droungarios of the vigla, the dikaiodotes, the protoasecretis, the eparchos of the city, the koiaistor and the epi ton kriseon. The latter could delegate the authority to try cases to the “small” or inferior judges. Consequently, the judges of the velum and the judges of the hippodrome could also be sent from Constantinople to the themes by the emperor or other officials, in order to examine some cases and then return to the capital. This is confirmed by the primary sources, which mention for example the case of judge of the hippodrome Michael Rhodios, who was sent by Alexios I Komnenos in 1084 from Constantinople to the region of Thessalonike, in order to examine a dispute between the Lavra monastery and the brother of the emperor, Adrian. Some years later Michael Rhodios was sent again to try cases in Thessalonike, but this time as krites of Boleron, Strymon and Thessalonike. Consequently, apart from the judge of Boleron, Strymon and Thessalonike, other judges delegated by the emperor or by high officers could also examine cases there, as happened in other themes. From the 14th century on, as Macedonia developed

  12. Joint Single-Channel Speech Separation and Speaker Identification

    In this paper, we propose a closed loop system to improve the performance of single-channel speech separation in a speaker independent scenario. The system is composed of two interconnected blocks: a separation block and a speaker identiſcation block. The improvement is accomplished...... by incorporating the speaker identities found by the speaker identiſcation block as additional information for the separation block, which converts the speaker-independent separation problem to a speaker-dependent one where the speaker codebooks are known. Simulation results show that the closed loop system...

  14. The role of fillers in listener attributions for speaker disfluency

    OpenAIRE

    D. Barr; Seyfeddinipur, M.

    2010-01-01

    When listeners hear a speaker become disfluent, they expect the speaker to refer to something new. What is the mechanism underlying this expectation? In a mouse-tracking experiment, listeners sought to identify images that a speaker was describing. Listeners more strongly expected new referents when they heard a speaker say um than when they heard a matched utterance where the um was replaced by noise. This expectation was speaker-specific: it depended on what was new and old for the current ...

  15. Rhetorical intentionality attribution: its ontogenesis in ordinary conversation.

    Science.gov (United States)

    Bonaiuto, M; Fasulo, A

    1997-12-01

    This paper addresses the assumption that the epistemological dichotomy between reality and its construction is an everyday rhetorical tool children and adults use in their explanations and arguments. Within a discursive psychology perspective, the phenomenon of attribution of rhetorical intentionality (AIR) is theoretically defined developing the notion of prepackaged interest attribution technique (Edwards & Potter, 1992). AIR consists in an explanation of others' discursive moves in terms of a rhetorical-argumentative activity; that is, in terms of a deliberate attempt aimed at construing and presenting reality as a function of the speaker's point of view, perspective and interests, in order to affect the listeners mental state (belief, knowledge, intention) or action. Theoretical links are made to the theory of mind paradigm in the study of intentionality attribution, particularly to the form of life approach which defines intentionality attribution in terms of language games. On this basis, the present study examines the structures and functions of AIR used by children and their parents in everyday conversation. Qualitative discourse analysis of transcripts of 22 dinner conversations from eight Italian families shows explicit and implicit AIR in children from three and a half to seven years of age. Moreover, parents attribute rhetorical intentionality to their children, contributing to their social construction as rhetorical speakers. AIR is used as a rhetorical strategy within disputes and argumentative contexts, often achieving topic closure. Results are discussed with reference to the ontological status of intentionalist talk.

  16. Both Earlier Times and the Future Are "Front": The Distinction Between Time- and Ego-Reference-Points in Mandarin Speakers' Temporal Representation.

    Xiao, Chengli; Zhao, Mengya; Chen, Lei

    2017-09-28

    Mandarin speakers, like most other language speakers around the world, use spatial terms to talk about time. However, the direction of their mental temporal representation along the front-back axis remains controversial because they use the spatial term "front" to refer to both earlier times (e.g., front-year means "the year before last") and the future (e.g., front-road means "prospect"). Although the linguistic distinction between time- and ego-reference-point spatiotemporal metaphors in Mandarin suggests a promising clarification of the above controversy, there is little empirical evidence verifying this distinction. In this study, Mandarin speakers' time- and ego-reference-point temporal representations on three axes (i.e., sagittal, lateral, and vertical) were separately examined through two tasks. In a time-reference-point task, Mandarin speakers judged whether the time point of the second picture was earlier or later than the time point of the first picture, while in an ego-reference-point task, they judged whether an event or phase had happened in the past or would happen in the future. The results indicate that Mandarin speakers construe an earlier-times-in-front-of-later-times temporal sequence and adopt the front-to-the-future orientation.

    Full Text Available The present study aimed to see whether the results gained by Gibbs and O’Brian (1990 about the consistency of the idiom images can be generalized to other communities like the Persian community in their comprehension of idioms as well. It also tried to account for why many idioms have the figurative meaning they do and to explore whether people in different societies, cultures, and languages comprehend the idioms of their languages in the same way. The participants from different areas of Iran at the time of data collection were native speakers of Farsi from both sexes. The material used for data collection in this study consists of a questionnaire comprising 20 Persian idioms. Four idioms expressed figurative meanings about anger, four about taking risks, four about insanity, four about vanity, four about talkativeness. Then the participants were asked about Causation, Intentionality, Manner, Consequence, Negative Consequence, and Reversibility. Each participant’s description of their mental images was analyzed for its general characteristics and the different general characteristics for people’s mental images for each idiom were calculated across subjects. The results suggested that the conceptual metaphor underlies the comprehension of idioms and this is not limited to the speakers of English only, but can also be generalized to speakers of a different language like Farsi and also to the speakers of different dialects of Farsi, since the participants in this study were from different provinces of Iran.

  19. Intentionality, Representation, and Anticipation

    De Preester, Helena

    2002-09-01

    Both Brentano and Merleau-Ponty have developed an account of intentionality, which nevertheless differ profoundly in the following respect. According to Brentano, intentionality mainly is a matter of mental presentations. This marks the beginning of phenomenology's difficult relation with the nature of the intentional reference. Merleau-Ponty, on the other hand, has situated intentionality on the level of the body, a turn which has important implications for the nature of intentionality. Intentionality no longer is primarily based on having (re)presentations, but is rooted in the dynamics of the living body. To contrast those approaches enables us to make clear in what way intentionality is studied nowadays. On the one hand, intentionality is conceived of as a matter of formal-syntactical causality in cognitive science, and in particular in classical-computational theory. On the other hand, a interactivist approach offers a more Merleau-Ponty-like point of view, in which autonomy, embodiment and interaction are stressed.

    2008-01-01

    Speaker adaptive test normalization (Atnorm) is the most effective approach of the widely used score normalization in text-independent speaker verification, which selects speaker adaptive impostor cohorts with an extra development corpus in order to enhance the recognition performance. In this paper, an improved implementation of Atnorm that can offer overall significant advantages over the original Atnorm is presented. This method adopts a novel cross similarity measurement in speaker adaptive cohort model selection without an extra development corpus. It can achieve a comparable performance with the original Atnorm and reduce the computation complexity moderately. With the full use of the saved extra development corpus, the overall system performance can be improved significantly. The results are presented on NIST 2006 Speaker Recognition Evaluation data corpora where it is shown that this method provides significant improvements in system performance, with relatively 14.4% gain on equal error rate (EER) and 14.6% gain on decision cost function (DCF) obtained as a whole.

    2016-03-01

    Full Text Available Subject of Research. The paper presents a semi-automatic speaker verification system based on comparing of formant values, statistics of phone lengths and melodic characteristics as well. Due to the development of speech technology, there is an increased interest now in searching for expert speaker verification systems, which have high reliability and low labour intensiveness because of the automation of data processing for the expert analysis. System Description. We present a description of a novel system analyzing similarity or distinction of speaker voices based on comparing statistics of phone lengths, formant features and melodic characteristics. The characteristic feature of the proposed system based on fusion of methods is a weak correlation between the analyzed features that leads to a decrease in the error rate of speaker recognition. The system advantage is the possibility to carry out rapid analysis of recordings since the processes of data preprocessing and making decision are automated. We describe the functioning methods as well as fusion of methods to combine their decisions. Main Results. We have tested the system on the speech database of 1190 target trials and 10450 non-target trials, including the Russian speech of the male and female speakers. The recognition accuracy of the system is 98.59% on the database containing records of the male speech, and 96.17% on the database containing records of the female speech. It was also experimentally established that the formant method is the most reliable of all used methods. Practical Significance. Experimental results have shown that proposed system is applicable for the speaker recognition task in the course of phonoscopic examination.

    Full Text Available Professional judges in traffic courts sentence many hundreds of offenders per year. Using 639 case files from archives, we compared the Matching Heuristic (MH to compensatory, weighing algorithms (WM. We modeled and cross validated the models on different subsets of the data, and took several other methodological precautions such as allowing each model to select the optimal number of variables and ordering and weighing the variables in accordance to different logics. We did not reproduce the finding by Dhami (2003, who found the MH to be superior to a compensatory algorithm in modeling bail-granting decisions. These simulations brought out the inner logic of the two family of models, showing what combination of parameters works best. It remains remarkable that using only a fraction of the variables and combining them non-compensatorily, MH obtained nearly as good a fit as the weighing method.

    Full Text Available This paper presents the effectiveness of perceptual features and iterative clustering approach forperforming both speech and speaker recognition. Procedure used for formation of training speech is differentfor developing training models for speaker independent speech and text independent speaker recognition. So,this work mainly emphasizes the utilization of clustering models developed for the training data to obtainbetter accuracy as 91%, 91% and 99.5% for mel frequency perceptual linear predictive cepstrum with respectto three categories such as speaker identification, isolated digit recognition and continuous speechrecognition. This feature also produces 9% as low equal error rate which is used as a performance measurefor speaker verification. The work is experimentally evaluated on the set of isolated digits and continuousspeeches from TI digits_1 and TI digits_2 database for speech recognition and on speeches of 50 speakersrandomly chosen from TIMIT database for speaker recognition. The noteworthy feature of speakerrecognition algorithm is to evaluate the testing procedure on identical messages of all the 50 speakers,theoretical validation of results using F-ratio and validation of results by statistical analysis using2 cdistribution.

    2017-01-01

    A growing number of studies are investigating the way that aesthetic experiences are generated across different media. Empathy with a perceived human artist has been suggested as a common mechanism [1]. In this study, people heard 30 s excerpts of ambiguous music and poetry preceded by neutral, positively valenced, or negatively valenced information about the composer's or author's intent. The information influenced their perception of the excerpts-excerpts paired with positive intent information were perceived as happier and excerpts paired with negative intent information were perceived as sadder (although across intent conditions, musical excerpts were perceived as happier than poetry excerpts). Moreover, the information modulated the aesthetic experience of the excerpts in different ways for the different excerpt types: positive intent information increased enjoyment and the degree to which people found the musical excerpts to be moving, but negative intent information increased these qualities for poetry. Additionally, positive intent information was judged to better match musical excerpts and negative intent information to better match poetic excerpts. These results suggest that empathy with a perceived human artist is indeed an important shared factor across experiences of music and poetry, but that other mechanisms distinguish the generation of aesthetic appreciation between these two media.

  7. Damage to ventromedial prefrontal cortex impairs judgment of harmful intent

    2011-01-01

    Summary Moral judgments, whether delivered in ordinary experience or in the courtroom, depend on our ability to infer intentions. We forgive unintentional or accidental harms and condemn failed attempts to harm. Prior work demonstrates that patients with damage to the ventromedial prefrontal cortex (VMPC) deliver abnormal judgments in response to moral dilemmas, and that these patients are especially impaired in triggering emotional responses to inferred or abstract events (e.g., intentions), as opposed to real or actual outcomes. We therefore predicted that VMPC patients would deliver abnormal moral judgments of harmful intentions in the absence of harmful outcomes, as in failed attempts to harm. This prediction was confirmed in the current study: VMPC patients judged attempted harms including attempted murder as more morally permissible relative to controls. These results highlight the critical role of the VMPC in processing harmful intent for moral judgment. PMID:20346759

    In this paper a new text-independent speaker verification method GSMSV is proposed based on likelihood score normalization. In this novel method a global speaker model is established to represent the universal features of speech and normalize the likelihood score. Statistical analysis demonstrates that this normalization method can remove common factors of speech and bring the differences between speakers into prominence. As a result the equal error rate is decreased significantly,verification procedure is accelerated and system adaptability to speaking speed is improved.

  11. Limited data speaker identification

    2010-10-01

    In this paper, the task of identifying the speaker using limited training and testing data is addressed. Speaker identification system is viewed as four stages namely, analysis, feature extraction, modelling and testing. The speaker identification performance depends on the techniques employed in these stages. As demonstrated by different experiments, in case of limited training and testing data condition, owing to less data, existing techniques in each stage will not provide good performance. This work demonstrates the following: multiple frame size and rate (MFSR) analysis provides improvement in the analysis stage, combination of mel frequency cepstral coefficients (MFCC), its temporal derivatives $(\\Delta,\\Delta \\Delta)$, linear prediction residual (LPR) and linear prediction residual phase (LPRP) features provides improvement in the feature extraction stage and combination of learning vector quantization (LVQ) and gaussian mixture model – universal background model (GMM–UBM) provides improvement in the modelling stage. The performance is further improved by integrating the proposed techniques at the respective stages and combining the evidences from them at the testing stage. To achieve this, we propose strength voting (SV), weighted borda count (WBC) and supporting systems (SS) as combining methods at the abstract, rank and measurement levels, respectively. Finally, the proposed hierarchical combination (HC) method integrating these three methods provides significant improvement in the performance. Based on these explorations, this work proposes a scheme for speaker identification under limited training and testing data.

    Human cooperative communication involves both an informative intention that the recipient understands the content of the signal and also a (Gricean) communicative intention that the recipient recognizes that the speaker has an informative intention. The degree to which children understand this 2-layered nature of communication is the subject of some debate. One phenomenon that would seem to constitute clear evidence of such understanding is hidden authorship, in which informative acts are produced but with the communicative intent behind them intentionally hidden. In this study, 3- and 5-year-old children were told that an adult was seeking a toy but wanted to find it on her own. Children of both ages often did something to make the toy easier for the adult to see while at the same time concealing their actions in some way. This suggests that by the age of 3, children are able to separate the multiple layers of intentionality involved in human cooperative communication.

    1999-06-16

    The objective of this research is to develop a system capable of identifying speakers on wiretaps from a large database (>500 speakers) with a short search time duration (<30 seconds), and with better than 90% accuracy. Much previous research in speaker recognition has led to algorithms that produced encouraging preliminary results, but were overwhelmed when applied to populations of more than a dozen or so different speakers. The authors are investigating a solution to the "large population" problem by seeking two completely different kinds of characterizing features. These features are he techniques of Neuro-Linguistic Programming (NLP) and the continuous wavelet transform (CWT). NLP extracts precise neurological, verbal and non-verbal information, and assimilates the information into useful patterns. These patterns are based on specific cues demonstrated by each individual, and provide ways of determining congruency between verbal and non-verbal cues. The primary NLP modalities are characterized through word spotting (or verbal predicates cues, e.g., see, sound, feel, etc.) while the secondary modalities would be characterized through the speech transcription used by the individual. This has the practical effect of reducing the size of the search space, and greatly speeding up the process of identifying an unknown speaker. The wavelet-based line of investigation concentrates on using vowel phonemes and non-verbal cues, such as tempo. The rationale for concentrating on vowels is there are a limited number of vowels phonemes, and at least one of them usually appears in even the shortest of speech segments. Using the fast, CWT algorithm, the details of both the formant frequency and the glottal excitation characteristics can be easily extracted from voice waveforms. The differences in the glottal excitation waveforms as well as the formant frequency are evident in the CWT output. More significantly, the CWT reveals significant detail of the glottal excitation

Then, the most commonly speech parameterization used in speaker verification, namely, cepstral analysis, is detailed. Gaussian mixture modeling, which is the speaker modeling technique used in most systems, is then explained. A few speaker modeling alternatives, namely, neural networks and support vector machines, are mentioned. Normalization of scores is then explained, as this is a very important step to deal with real-world data. The evaluation of a speaker verification system is then detailed, and the detection error trade-off (DET) curve is explained. Several extensions of speaker verification are then enumerated, including speaker tracking and segmentation by speakers. Then, some applications of speaker verification are proposed, including on-site applications, remote applications, applications relative to structuring audio information, and games. Issues concerning the forensic area are then recalled, as we believe it is very important to inform people about the actual performance and limitations of speaker verification systems. This paper concludes by giving a few research trends in speaker verification for the next couple of years.

    The effect of speaker variability on accessing the form and meaning of spoken words was evaluated in two short-term priming experiments. In the repetition priming experiment, participants listened to repeated or unrelated prime-target pairs, in which the prime and target were produced by the same speaker or different speakers. The results showed…

  8. Application of combined temporal and spectral processing methods for speaker recognition under noisy, reverberant or multi-speaker environments

    2009-10-01

    This paper presents an experimental evaluation of the combined temporal and spectral processing methods for speaker recognition task under noise, reverberation or multi-speaker environments. Automatic speaker recognition system gives good performance in controlled environments. Speech recorded in real environments by distant microphones is degraded by factors like background noise, reverberation and interfering speakers. This degradation strongly affects the performance of the speaker recognition system. Combined temporal and spectral processing (TSP) methods proposed in our earlier study are used for pre-processing to improve the speaker-specific features and hence the speaker recognition performance. Different types of degradation like background noise, reverberation and interfering speaker are considered for evaluation. The evaluation is carried out for the individual temporal processing, spectral processing and the combined TSP method. The experimental results show that the combined TSP methods give relatively higher recognition performance compared to either temporal or spectral processing alone.

  9. Acoustic Model Training Using Pseudo-Speaker Features Generated by MLLR Transformations for Robust Speaker-Independent Speech Recognition

    2012-01-01

    A novel speech feature generation-based acoustic model training method for robust speaker-independent speech recognition is proposed. For decades, speaker adaptation methods have been widely used. All of these adaptation methods need adaptation data. However, our proposed method aims to create speaker-independent acoustic models that cover not only known but also unknown speakers. We achieve this by adopting inverse maximum likelihood linear regression (MLLR) transformation-based feature gene...

    2011-03-10

    To evaluate the impact guest speakers have on student development in a professional development seminar series. Over a 5-semester period, presentations were given by 18 guest speakers as part of a professional development seminar series. A 28-item survey instrument was constructed and administered to 68 students to assess the impact of the guest speakers on the students' professional development. Forty-six (68%) students completed the survey instrument, and the results demonstrated the value of the guest speakers, most notably in the areas of career development and professional responsibility. Exposing pharmacy students to guest speakers from varied pharmacy career paths positively impacted students' knowledge of career options and professional development.

  12. Revisiting Phenomenal Intentionality

    Directory of Open Access Journals (Sweden)

    Farid Masrour

    2016-04-01

    Full Text Available This essay has two goals. The goal of the first section is to raise a few clarificatory questions about the exact contour of Crane’s account of intentionality, its relation to phenomenology, and his motivation for it. The second section aims to describe a general worry about programs that combine a broadly anti-externalist outlook on intentionality with the idea that there is an intimate connection between phenomenology and intentionality. I argue that programs like this either suffer from a problem that I call intentional luck or, in the attempt to avoid this problem, have to weaken the connection between intentionality and phenomenology. Since Crane’s general outlook falls under this program, it is subject to this worry.

  13. How Cognitive Load Influences Speakers' Choice of Referring Expressions.

    Science.gov (United States)

    Vogels, Jorrig; Krahmer, Emiel; Maes, Alfons

    2015-08-01

    We report on two experiments investigating the effect of an increased cognitive load for speakers on the choice of referring expressions. Speakers produced story continuations to addressees, in which they referred to characters that were either salient or non-salient in the discourse. In Experiment 1, referents that were salient for the speaker were non-salient for the addressee, and vice versa. In Experiment 2, all discourse information was shared between speaker and addressee. Cognitive load was manipulated by the presence or absence of a secondary task for the speaker. The results show that speakers under load are more likely to produce pronouns, at least when referring to less salient referents. We take this finding as evidence that speakers under load have more difficulties taking discourse salience into account, resulting in the use of expressions that are more economical for themselves. © 2014 Cognitive Science Society, Inc.

  14. Speaker-Adaptive Speech Recognition Based on Surface Electromyography

    Science.gov (United States)

    Wand, Michael; Schultz, Tanja

    We present our recent advances in silent speech interfaces using electromyographic signals that capture the movements of the human articulatory muscles at the skin surface for recognizing continuously spoken speech. Previous systems were limited to speaker- and session-dependent recognition tasks on small amounts of training and test data. In this article we present speaker-independent and speaker-adaptive training methods which allow us to use a large corpus of data from many speakers to train acoustic models more reliably. We use the speaker-dependent system as baseline, carefully tuning the data preprocessing and acoustic modeling. Then on our corpus we compare the performance of speaker-dependent and speaker-independent acoustic models and carry out model adaptation experiments.

  15. Assessment of variation between and within speakers

    Science.gov (United States)

    Bahr, Ruth Huntley

    2003-10-01

    While few individuals would argue that vocal cues can signal a person's identity, it is difficult to specify exactly which parameter(s) provide the most salient information for speaker identification. Previous literature has suggested that speaking fundamental frequency, long-term spectra, vowel formant frequencies, and speech tempo can provide speaker-specific information. However, investigations focused on automatic speaker identification have provided less than satisfactory results. These findings could be related to how each acoustic parameter is measured or, more probably, to the idea that these acoustic parameters interact in specific ways that may be more obvious in the perceptual realm and may vary across speaking situations. To further complicate matters, individuals may speak more than one language or use multiple dialects. Little is known about the effect of code switching on voice production and identification. The purpose of this presentation is to present some of the relevant literature on voice recognition and factors related to misidentification. The role of intraspeaker variability will be discussed with a special emphasis on bilingualism and bidialectalism. Implications for voice production in augmentative and alternative communication devices will be described.

  16. Sequence complexity effects on speech production in healthy speakers and speakers with hypokinetic or ataxic dysarthria.

    2013-01-01

    The present study investigated the effects of sequence complexity, defined in terms of phonemic similarity and phonotoactic probability, on the timing and accuracy of serial ordering for speech production in healthy speakers and speakers with either hypokinetic or ataxic dysarthria. Sequences were comprised of strings of consonant-vowel (CV) syllables with each syllable containing the same vowel, /a/, paired with a different consonant. High complexity sequences contained phonemically similar consonants, and sounds and syllables that had low phonotactic probabilities; low complexity sequences contained phonemically dissimilar consonants and high probability sounds and syllables. Sequence complexity effects were evaluated by analyzing speech error rates and within-syllable vowel and pause durations. This analysis revealed that speech error rates were significantly higher and speech duration measures were significantly longer during production of high complexity sequences than during production of low complexity sequences. Although speakers with dysarthria produced longer overall speech durations than healthy speakers, the effects of sequence complexity on error rates and speech durations were comparable across all groups. These findings indicate that the duration and accuracy of processes for selecting items in a speech sequence is influenced by their phonemic similarity and/or phonotactic probability. Moreover, this robust complexity effect is present even in speakers with damage to subcortical circuits involved in serial control for speech.

  18. Understanding intentional actions from observers' viewpoints: A social neuroscience perspective.

    Science.gov (United States)

    Isoda, Masaki

    2016-11-01

    When we see others, we also try to 'see' their unobservable states of minds, such as beliefs, desires, and intentions. We carefully monitor others' actions, as we assume that those actions are outward manifestations of their internal states. Actors and observers can have divergent views on the cause of the same actions. Critically, it is often the observers' view that affects important decisions in social life, from deciding the optimal level of cooperation to judging moral responsibility and court's decisions. Thus, the judgment about intentionality and agency in others' actions determines the way in which the observer deals with the actor. The primate brain has two separate neural systems that function in understanding others' actions and intentions. The mirror system is activated by others' visible actions and predicts their physical consequences in goal terms, whereas the mentalizing system is primarily involved in the prediction of others' intentions and upcoming actions regardless of whether others' actions are directly observable or not. The functional roles of the two systems have sometimes been described as mutually independent or even oppositional. I propose a hypothesis that the two systems may collaborate closely for judging the sense of other-agency.

  19. Spelling and dialect: comparisons between speakers of African American vernacular English and White speakers.

    Science.gov (United States)

    Treiman, Rebecca

    2004-04-01

    One characteristic of African American vernacular English (AAVE) is final obstruent devoicing, where the final consonant of a word like rigid is pronounced more like /t/ than /d/. To determine whether this dialect characteristic influences adults' spelling, African American and White college students spelled words such as rigid and ballot, pronounced by either a speaker of their own dialect or a speaker of the other dialect. African Americans, especially those who often devoiced final /d/, were more likely than Whites to confuse d and t. Both African American and White spellers made more d/t confusions when the words were spoken by an African American experimenter than by a White experimenter. Thus, the different phonological systems of AAVE and White speakers can cause them to make different types of spelling errors. Discussions of AAVE and literacy have focused on its syntax, but its phonology must also be considered.

    In this paper, we propose a new software design of an online judge system for interactive theorem proving. The distinctive feature of this architecture is that our online judge system is distributed on the network and especially involves volunteer computing. In volunteers' computers, network bots (software robots) are executed and donate computational resources to the central host of the online judge system. Our proposed design improves fault tolerance and security. We gave an implementation to two different styles of interactive theorem prover, Coq and ACL2, and evaluated our proposed architecture. From the experiment on the implementation, we concluded that our architecture is efficient enough to be used practically.

  3. Tracking Intermittently Speaking Multiple Speakers Using a Particle Filter

    2009-01-01

    Full Text Available The problem of tracking multiple intermittently speaking speakers is difficult as some distinct problems must be addressed. The number of active speakers must be estimated, these active speakers must be identified, and the locations of all speakers including inactive speakers must be tracked. In this paper we propose a method for tracking intermittently speaking multiple speakers using a particle filter. In the proposed algorithm the number of active speakers is firstly estimated based on the Exponential Fitting Test (EFT, a source number estimation technique which we have proposed. The locations of the speakers are then tracked using a particle filtering framework within which the decomposed likelihood is used in order to decouple the observed audio signal and associate each element of the decomposed signal with an active speaker. The tracking accuracy is then further improved by the inclusion of a silence region detection step and estimation of the noise-only covariance matrix. The method was evaluated using live recordings of 3 speakers and the results show that the method produces highly accurate tracking results.

  5. Speaker adapted dynamic lexicons containing phonetic deviations of words

    2009-01-01

    Speaker variability is an important source of speech variations which makes continuous speech recognition a difficult task. Adapting automatic speech recognition (ASR) models to the speaker variations is a well-known strategy to cope with the challenge. Almost all such techniques focus on developing adaptation solutions within the acoustic models of the ASR systems. Although variations of the acoustic features constitute an important portion of the inter-speaker variations, they do not cover variations at the phonetic level. Phonetic variations are known to form an important part of variations which are influenced by both micro-segmental and suprasegmental factors. Inter-speaker phonetic variations are influenced by the structure and anatomy of a speaker's articulatory system and also his/her speaking style which is driven by many speaker background characteristics such as accent, gender, age, socioeconomic and educational class. The effect of inter-speaker variations in the feature space may cause explicit phone recognition errors. These errors can be compensated later by having appropriate pronunciation variants for the lexicon entries which consider likely phone misclassifications besides pronunciation. In this paper, we introduce speaker adaptive dynamic pronunciation models, which generate different lexicons for various speaker clusters and different ranges of speech rate. The models are hybrids of speaker adapted contextual rules and dynamic generalized decision trees, which take into account word phonological structures, rate of speech, unigram probabilities and stress to generate pronunciation variants of words. Employing the set of speaker adapted dynamic lexicons in a Farsi (Persian) continuous speech recognition task results in word error rate reductions of as much as 10.1% in a speaker-dependent scenario and 7.4% in a speaker-independent scenario.

    The problem of text-dependent speaker verification under noisy conditions is becoming ever more relevant, due to increased usage for authentication in real-world applications. Classical methods for noise reduction such as spectral subtraction and Wiener filtering introduce distortion and do...... not perform well in this setting.

We furthermore propose a new approach based...

    The ability to vary language style or register is important for successfully navigating social situations. For example, we speak differently to our boss than we do to our children. This project examined whether high-functioning speakers with ASD were able to vary the language used for requests along continua of "politeness/bossiness", whether any such adjustments were similar to those made by appropriately matched controls, and whether speakers with ASD were able to accurately interpret politeness/bossiness registers. High-functioning children and adolescents (aged 6-16) with ASD were compared to matched typically developing children and adolescents on ability to (1) produce both "nice" and "bossy" requests to puppet listeners and, (2) to judge which of two requests was more polite. Contrary to expectations, participants with ASD were as adept as controls in both producing and judging polite and bossy requests. These results suggest that, at least for high-functioning children and adolescents with ASD, some skill at adjusting language register exists in their repertoire. Future research should examine whether this skill is also present in younger children and in unstructured interactions. If these results hold, clinicians may be able to focus their intervention on teaching strategies for successful use of behaviours that already exist rather than training the responses themselves. The reader will become familiar with the functional importance of varying language registers or style according to situational demands. In addition, teaching a strategy for how to determine when a particular language behaviour should be used may sometimes be more effective than training the specific language response.

  8. Is Intentionality Real Enough?

    Full Text Available According to Crane intentionality is nothing less than the mark of the mental. Nonetheless, there are many issues raised by this concept, beginning with the problem of non-existent relata. In this comment-article I discuss the concept of intentionality in its generality, trying to state its ontological status and to assess its explanatory dispensability. In particular, I focus on the argument, addressed by Crane, whereby Wittgenstein eliminates intentionality, characterizing it as a grammatical fiction, a pseudo-entity created by the grammar of the language of mental states ascriptions. I will argue that: (1 although Crane’s specific argument against Wittgenstein is not conclusive, Wittgenstein’s linguistic strategy does not work; and yet (2 we should not be committed to a robust realist (that is, ontologically strong account of intentionality.

    Is it acceptable and moral to sacrifice a few people's lives to save many others? Research on moral dilemmas in psychology, experimental philosophy, and neuropsychology has shown that respondents judge utilitarian personal moral actions (footbridge dilemma) as less appropriate than equivalent utilitarian impersonal moral actions (trolley dilemma). Accordingly, theorists (e.g., Greene et al., 2001) have argued that judgments of appropriateness in personal moral dilemmas are more emotionally salient and cognitively demanding (taking more time to be rational) than impersonal moral dilemmas. Our novel findings show an effect of psychological accessibility (driven by partial contextual information; Kahneman, 2003) on utilitarian moral behavior and response time for rational choices. Enhanced accessibility of utilitarian outcomes through comprehensive information about moral actions and consequences boosted utility maximization in moral choices, with rational choices taking less time. Moreover, our result suggests that previous results indicating emotional interference, with rational choices taking more time to make, may have been artifacts of presenting partial information.

    Recipients process information from speech and co-speech gestures, but it is currently unknown how this processing is influenced by the presence of other important social cues, especially gaze direction, a marker of communicative intent. Such cues may modulate neural activity in regions associated either with the processing of ostensive cues, such as eye gaze, or with the processing of semantic information, provided by speech and gesture. Participants were scanned (fMRI) while taking part in triadic communication involving two recipients and a speaker. The speaker uttered sentences that were and were not accompanied by complementary iconic gestures. Crucially, the speaker alternated her gaze direction, thus creating two recipient roles: addressed (direct gaze) vs unaddressed (averted gaze) recipient. The comprehension of Speech&Gesture relative to SpeechOnly utterances recruited middle occipital, middle temporal and inferior frontal gyri, bilaterally. The calcarine sulcus and posterior cingulate cortex were sensitive to differences between direct and averted gaze. Most importantly, Speech&Gesture utterances, but not SpeechOnly utterances, produced additional activity in the right middle temporal gyrus when participants were addressed. Marking communicative intent with gaze direction modulates the processing of speech-gesture utterances in cerebral areas typically associated with the semantic processing of multi-modal communicative acts. © The Author (2014).

  11. Speaker's voice as a memory cue.

    Campeanu, Sandra; Craik, Fergus I M; Alain, Claude

    2015-02-01

    Speaker's voice occupies a central role as the cornerstone of auditory social interaction. Here, we review the evidence suggesting that speaker's voice constitutes an integral context cue in auditory memory. Investigation into the nature of voice representation as a memory cue is essential to understanding auditory memory and the neural correlates which underlie it. Evidence from behavioral and electrophysiological studies suggest that while specific voice reinstatement (i.e., same speaker) often appears to facilitate word memory even without attention to voice at study, the presence of a partial benefit of similar voices between study and test is less clear. In terms of explicit memory experiments utilizing unfamiliar voices, encoding methods appear to play a pivotal role. Voice congruency effects have been found when voice is specifically attended at study (i.e., when relatively shallow, perceptual encoding takes place). These behavioral findings coincide with neural indices of memory performance such as the parietal old/new recollection effect and the late right frontal effect. The former distinguishes between correctly identified old words and correctly identified new words, and reflects voice congruency only when voice is attended at study. Characterization of the latter likely depends upon voice memory, rather than word memory. There is also evidence to suggest that voice effects can be found in implicit memory paradigms. However, the presence of voice effects appears to depend greatly on the task employed. Using a word identification task, perceptual similarity between study and test conditions is, like for explicit memory tests, crucial. In addition, the type of noise employed appears to have a differential effect. While voice effects have been observed when white noise is used at both study and test, using multi-talker babble does not confer the same results. In terms of neuroimaging research modulations, characterization of an implicit memory effect

    The three-judges protocol, recently advocated by Mclver and Morgan as an example of stepwise refinement of security protocols, studies how to securely compute the majority function to reach a final verdict without revealing each individual judge's decision. We extend their protocol in two different ways for an arbitrary number of 2n+1 judges. The first generalisation is inherently centralised, in the sense that it requires a judge as a leader who collects information from others, computes the majority function, and announces the final result. A different approach can be obtained by slightly modifying the well-known dining cryptographers protocol, however it reveals the number of votes rather than the final verdict. We define a notion of conditional anonymity in order to analyse these two solutions. Both of them have been checked in the model checker MCMAS.

    2012-04-01

    In Arizona v. Fulminante (1991), the U.S. Supreme Court opened the door for appellate judges to conduct a harmless error analysis of erroneously admitted, coerced confessions. In this study, 132 judges from three states read a murder case summary, evaluated the defendant's guilt, assessed the voluntariness of his confession, and responded to implicit and explicit measures of harmless error. Results indicated that judges found a high-pressure confession to be coerced and hence improperly admitted into evidence. As in studies with mock jurors, however, the improper confession significantly increased their conviction rate in the absence of other evidence. On the harmless error measures, judges successfully overruled the confession when required to do so, indicating that they are capable of this analysis.

    In the speakers' bureau system, physicians are recruited and trained by pharmaceutical, biotechnology, and medical device companies to deliver information about products to other physicians, in exchange for a fee. Using publicly available disclosures, we assessed the thesis that speakers' bureau involvement is not a feature of academic medicine in Canada, by estimating the prevalence of participation in speakers' bureaus among Canadian faculty in one medical specialty, cardiology. We analyzed the relevant features of an actual contract made public by the physician addressee and applied the Canadian Medical Association (CMA) guidelines on physician-industry relations to participation in a speakers' bureau. We argue that speakers' bureau participation constitutes a form of peer selling that should be understood to contravene the prohibition on product endorsement in the CMA Code of Ethics. Academic medical institutions, in conjunction with regulatory colleges, should continue and strengthen their policies to address participation in speakers' bureaus.

    Dialect Accent Features for Establishing Speaker Identity: A Case Study discusses the subject of forensic voice identification and speaker profiling. Specifically focusing on speaker profiling and using dialects of the Hindi language, widely used in India, the authors have contributed to the body of research on speaker identification by using accent feature as the discriminating factor. This case study contributes to the understanding of the speaker identification process in a situation where unknown speech samples are in different language/dialect than the recording of a suspect. The authors' data establishes that vowel quality, quantity, intonation and tone of a speaker as compared to Khariboli (standard Hindi) could be the potential features for identification of dialect accent.

    2015-09-01

    Full Text Available Person identification, especially in critical environments, has always been a subject of great interest. However, it has gained a new dimension in a world threatened by a new kind of terrorism that uses social networks (e.g. YouTube to broadcast its message. In this new scenario, classical identification methods (such fingerprints or face recognition have been forcedly replaced by alternative biometric characteristics such as voice, as sometimes this is the only feature available. Through the present paper, a new methodology to characterize speakers will be shown. This methodology is benefiting from the advances achieved during the last years in understanding and modelling voice production. The paper hypothesizes that a gender dependent characterization of speakers combined with the use of a new set of biometric parameters extracted from the components resulting from the deconstruction of the voice into its glottal source and vocal tract estimates, will enhance recognition rates when compared to classical approaches. A general description about the main hypothesis and the methodology followed to extract gender-dependent extended biometric parameters are given. Experimental validation is carried out both on a highly controlled acoustic condition database, and on a mobile phone network recorded under non-controlled acoustic conditions.

  11. A Principle of Intentionality

    Science.gov (United States)

    Turner, Charles K.

    2017-01-01

    The mainstream theories and models of the physical sciences, including neuroscience, are all consistent with the principle of causality. Wholly causal explanations make sense of how things go, but are inherently value-neutral, providing no objective basis for true beliefs being better than false beliefs, nor for it being better to intend wisely than foolishly. Dennett (1987) makes a related point in calling the brain a syntactic (procedure-based) engine. He says that you cannot get to a semantic (meaning-based) engine from there. He suggests that folk psychology revolves around an intentional stance that is independent of the causal theories of the brain, and accounts for constructs such as meanings, agency, true belief, and wise desire. Dennett proposes that the intentional stance is so powerful that it can be developed into a valid intentional theory. This article expands Dennett’s model into a principle of intentionality that revolves around the construct of objective wisdom. This principle provides a structure that can account for all mental processes, and for the scientific understanding of objective value. It is suggested that science can develop a far more complete worldview with a combination of the principles of causality and intentionality than would be possible with scientific theories that are consistent with the principle of causality alone.

  14. Effective Presentation Speech Support System for Representing Emphasis-Intention

    Directory of Open Access Journals (Sweden)

    Tomoko Kojiri

    2015-12-01

    Full Text Available A research presentation integrates slides and speech. If these two aspects do not represent the same intention, the presentation will probably fail to effectively explain the presenter’s intention. This paper focuses on the representation of the critical contents in a presentation. In an effective speech, the speaker adds more intonation and stress to emphasize the importance of the slide contents. Audiences recognize that important contents are those that are explained in a stronger voice or that are said after a short pause. However, in ineffective speeches, such voice effects do not always correspond to the important contents that are indicated by slides. On slides, the important contents are represented by levels of text indentation and size, color, and animation. This research develops a presentation speech support system that estimates important contents from slides and voices that might be recognized by audiences and extracts numerical differences. In addition, the system provides comments and feedback to improve speeches.

    Directory of Open Access Journals (Sweden)

    Machteld W. de Hoon

    2014-11-01

    Full Text Available This paper explores the changes that have taken place in the attitude of judges towards their role and tasks as well as actual judicial practices. The result of this exploration is a reflection upon the challenges and opportunities for a new, more responsive judge. The main characteristic of this new judge is that he or she looks beyond the purely legal coordinates of the dispute, in order to discuss which method of dispute resolution (a settlement, a referral to mediation or a court decision is most likely to result in a viable and sustainable solution. These changes in attitude are part of broader developments that have taken place in actual judicial practices. The context in which these changes have occurred helps us to gain a better understanding of the changes, the barriers to change and the opportunities to overcome these challenges. The leading assumption in this research is that during the past ten years there has been an extensive change in the way judges think about their role in dispute resolution and at the same time many judges experience difficulties in applying their new-found understanding to their work in the courts. Our data have been gathered through court observations, interviews and expert meetings. In addition, our analyses are based on relevant literature in the field of judicial dispute resolution (JDR as well as insights from our own previous research projects. We primarily focus on civil and administrative disputes in the Netherlands. Occasionally, we also point to trends and challenges elsewhere.

    2016-05-01

    This article discusses the impact of multilayer neural network parameters for speaker identification. The main task of speaker identification is to find a specific person in the known set of speakers. It means that the voice of an unknown speaker (wanted person) belongs to a group of reference speakers from the voice database. One of the requests was to develop the text-independent system, which means to classify wanted person regardless of content and language. Multilayer neural network has been used for speaker identification in this research. Artificial neural network (ANN) needs to set parameters like activation function of neurons, steepness of activation functions, learning rate, the maximum number of iterations and a number of neurons in the hidden and output layers. ANN accuracy and validation time are directly influenced by the parameter settings. Different roles require different settings. Identification accuracy and ANN validation time were evaluated with the same input data but different parameter settings. The goal was to find parameters for the neural network with the highest precision and shortest validation time. Input data of neural networks are a Mel-frequency cepstral coefficients (MFCC). These parameters describe the properties of the vocal tract. Audio samples were recorded for all speakers in a laboratory environment. Training, testing and validation data set were split into 70, 15 and 15 %. The result of the research described in this article is different parameter setting for the multilayer neural network for four speakers.

  15. A neural mechanism for recognizing speech spoken by different speakers.

    Science.gov (United States)

    Kreitewolf, Jens; Gaudrain, Etienne; von Kriegstein, Katharina

    2014-05-01

    Understanding speech from different speakers is a sophisticated process, particularly because the same acoustic parameters convey important information about both the speech message and the person speaking. How the human brain accomplishes speech recognition under such conditions is unknown. One view is that speaker information is discarded at early processing stages and not used for understanding the speech message. An alternative view is that speaker information is exploited to improve speech recognition. Consistent with the latter view, previous research identified functional interactions between the left- and the right-hemispheric superior temporal sulcus/gyrus, which process speech- and speaker-specific vocal tract parameters, respectively. Vocal tract parameters are one of the two major acoustic features that determine both speaker identity and speech message (phonemes). Here, using functional magnetic resonance imaging (fMRI), we show that a similar interaction exists for glottal fold parameters between the left and right Heschl's gyri. Glottal fold parameters are the other main acoustic feature that determines speaker identity and speech message (linguistic prosody). The findings suggest that interactions between left- and right-hemispheric areas are specific to the processing of different acoustic features of speech and speaker, and that they represent a general neural mechanism when understanding speech from different speakers.

  17. Does knowing speaker sex facilitate vowel recognition at short durations?

    Science.gov (United States)

    Smith, David R R

    2014-05-01

    A man, woman or child saying the same vowel do so with very different voices. The auditory system solves the complex problem of extracting what the man, woman or child has said despite substantial differences in the acoustic properties of their voices. Much of the acoustic variation between the voices of men and woman is due to changes in the underlying anatomical mechanisms for producing speech. If the auditory system knew the sex of the speaker then it could potentially correct for speaker sex related acoustic variation thus facilitating vowel recognition. This study measured the minimum stimulus duration necessary to accurately discriminate whether a brief vowel segment was spoken by a man or woman, and the minimum stimulus duration necessary to accuately recognise what vowel was spoken. Results showed that reliable vowel recognition precedesreliable speaker sex discrimination, thus questioning the use of speaker sex information in compensating for speaker sex related acoustic variation in the voice. Furthermore, the pattern of performance across experiments where the fundamental frequency and formant frequency information of speaker's voices were systematically varied, was markedly different depending on whether the task was speaker-sex discrimination or vowel recognition. This argues for there being little relationship between perception of speaker sex (indexical information) and perception of what has been said (linguistic information) at short durations.

    2016-12-01

    Full Text Available Cross-cultural studies of speech acts in different linguistic contexts might have interesting implications for language researchers and practitioners. Drawing on the Speech Act Theory, the present study aimed at conducting a comparative study of request speech act in Persian and English. Specifically, the study endeavored to explore the request strategies used in daily interactions of Persian and English speakers based on directness level and supportive moves. To this end, English and Persian TV series were observed and requestive utterances were transcribed. The utterances were then categorized based on Blum-Kulka and Olshtain’s Cross-Cultural Study of Speech Act Realization Pattern (CCSARP for directness level and internal and external mitigation devises. According to the results, although speakers of both languages opted for the direct level as their most frequently used strategy in their daily interactions, the English speakers used more conventionally indirect strategies than the Persian speakers did, and the Persian speakers used more non-conventionally indirect strategies than the English speakers did. Furthermore, the analyzed data revealed the fact that American English speakers use more mitigation devices in their daily interactions with friends and family members than Persian speakers.

  7. Prosody in the hands of the speaker

    Full Text Available In everyday life, speech is accompanied by gestures. In the present study, two experiments tested the possibility that spontaneous gestures accompanying speech carry prosodic information. Experiment 1 showed that gestures provide prosodic information, as adults are able to perceive the congruency between low-pass filtered – thus unintelligible – speech and the gestures of the speaker. Experiment 2 shows that in the case of ambiguous sentences (i.e., sentences with two alternative meanings depending on their prosody mismatched prosody and gestures lead participants to choose more often the meaning signaled by gestures. Our results demonstrate that the prosody that characterizes speech is not a modality specific phenomenon: it is also perceived in the spontaneous gestures that accompany speech. We draw the conclusion that spontaneous gestures and speech form a single communication system where the suprasegmental aspects of spoken language are mapped to the motor-programs responsible for the production of both speech sounds and hand gestures.

  10. Affective processing in bilingual speakers: disembodied cognition?

    Science.gov (United States)

    Pavlenko, Aneta

    2012-01-01

    A recent study by Keysar, Hayakawa, and An (2012) suggests that "thinking in a foreign language" may reduce decision biases because a foreign language provides a greater emotional distance than a native tongue. The possibility of such "disembodied" cognition is of great interest for theories of affect and cognition and for many other areas of psychological theory and practice, from clinical and forensic psychology to marketing, but first this claim needs to be properly evaluated. The purpose of this review is to examine the findings of clinical, introspective, cognitive, psychophysiological, and neuroimaging studies of affective processing in bilingual speakers in order to identify converging patterns of results, to evaluate the claim about "disembodied cognition," and to outline directions for future inquiry. The findings to date reveal two interrelated processing effects. First-language (L1) advantage refers to increased automaticity of affective processing in the L1 and heightened electrodermal reactivity to L1 emotion-laden words. Second-language (L2) advantage refers to decreased automaticity of affective processing in the L2, which reduces interference effects and lowers electrodermal reactivity to negative emotional stimuli. The differences in L1 and L2 affective processing suggest that in some bilingual speakers, in particular late bilinguals and foreign language users, respective languages may be differentially embodied, with the later learned language processed semantically but not affectively. This difference accounts for the reduction of framing biases in L2 processing in the study by Keysar et al. (2012). The follow-up discussion identifies the limits of the findings to date in terms of participant populations, levels of processing, and types of stimuli, puts forth alternative explanations of the documented effects, and articulates predictions to be tested in future research.

  11. Utterance Verification for Text-Dependent Speaker Recognition

    DEFF Research Database (Denmark)

    Text-dependent automatic speaker verification naturally calls for the simultaneous verification of speaker identity and spoken content. These two tasks can be achieved with automatic speaker verification (ASV) and utterance verification (UV) technologies. While both have been addressed previously...... in the literature, a treatment of simultaneous speaker and utterance verification with a modern, standard database is so far lacking. This is despite the burgeoning demand for voice biometrics in a plethora of practical security applications. With the goal of improving overall verification performance, this paper...... reports different strategies for simultaneous ASV and UV in the context of short-duration, text-dependent speaker verification. Experiments performed on the recently released RedDots corpus are reported for three different ASV systems and four different UV systems. Results show that the combination...

  12. Speakers of different languages process the visual world differently.

    Chabal, Sarah; Marian, Viorica

    2015-06-01

    Language and vision are highly interactive. Here we show that people activate language when they perceive the visual world, and that this language information impacts how speakers of different languages focus their attention. For example, when searching for an item (e.g., clock) in the same visual display, English and Spanish speakers look at different objects. Whereas English speakers searching for the clock also look at a cloud, Spanish speakers searching for the clock also look at a gift, because the Spanish names for gift (regalo) and clock (reloj) overlap phonologically. These different looking patterns emerge despite an absence of direct language input, showing that linguistic information is automatically activated by visual scene processing. We conclude that the varying linguistic information available to speakers of different languages affects visual perception, leading to differences in how the visual world is processed.

  13. Data-Model Relationship in Text-Independent Speaker Recognition

    Directory of Open Access Journals (Sweden)

    Stapert Robert

    2005-01-01

    Full Text Available Text-independent speaker recognition systems such as those based on Gaussian mixture models (GMMs do not include time sequence information (TSI within the model itself. The level of importance of TSI in speaker recognition is an interesting question and one addressed in this paper. Recent works has shown that the utilisation of higher-level information such as idiolect, pronunciation, and prosodics can be useful in reducing speaker recognition error rates. In accordance with these developments, the aim of this paper is to show that as more data becomes available, the basic GMM can be enhanced by utilising TSI, even in a text-independent mode. This paper presents experimental work incorporating TSI into the conventional GMM. The resulting system, known as the segmental mixture model (SMM, embeds dynamic time warping (DTW into a GMM framework. Results are presented on the 2000-speaker SpeechDat Welsh database which show improved speaker recognition performance with the SMM.

    Speech recognition and speaker identification are important for authentication and verification in security purpose, but they are difficult to achieve. Speaker identification methods can be divided into text-independent and text-dependent. This paper presents a technique of text-dependent speaker identification using MFCC-domain support vector machine (SVM). In this work, melfrequency cepstrum coefficients (MFCCs) and their statistical distribution properties are used as features, which will be inputs to the neural network. This work firstly used sequential minimum optimization (SMO) learning technique for SVM that improve performance over traditional techniques Chunking, Osuna. The cepstrum coefficients representing the speaker characteristics of a speech segment are computed by nonlinear filter bank analysis and discrete cosine transform. The speaker identification ability and convergence speed of the SVMs are investigated for different combinations of features. Extensive experimental results on several sam...

  15. Judges Awareness, Understanding, and Application of Digital Evidence

    Directory of Open Access Journals (Sweden)

    Gary C Kessler

    2011-03-01

    Full Text Available As digital evidence grows in both volume and importance in criminal and civil courts, judges need to fairly and justly evaluate the merits of the offered evidence. To do so, judges need a general understanding of the underlying technologies and applications from which digital evidence is derived. Due to the relative newness of the computer forensics field, there have been few studies on the use of digital forensic evidence and none about judges’ relationship with digital evidence.This paper describes a recent study, using grounded theory methods, into judges’ awareness, knowledge, and perceptions of digital evidence. This study is the first in the U.S. to examine judges and digital forensics, thus opening up a new avenue of research. It is the second time that grounded theory has been employed in a published digital forensics study, demonstrating the applicability of that methodology to this discipline.

  16. A judging principle of crucial vibrational transmission paths in plates

    Wang, Bin; Li, Dong-Xu; Jiang, Jian-Ping; Liao, Yi-Huan

    2016-10-01

    This paper developed a judging principle of crucial vibrational transmission path (VTP) in plates. Novel generalized definitions of VTPs are given referred to the meaning of streamlines. And by comparing governing equations, the similarity between energy flow and fluid motion is firstly found so that an analytic method of VTPs in plates is proposed by analogy with fluid motion. Hereafter, the crucial VTP is defined for energy flows at objective points and relative judging criteria is given. Finally, based on two numerical experiments of passive control, the judging principle is indirectly verified by comparing the reduction effects of energy flows at focused points and relative judgment results of crucial VTPs. This paper is meaningful for analyzing and applying the VTPs in plates to guide the control design in future.

  2. Accounting for the listener: comparing the production of contrastive intonation in typically-developing speakers and speakers with autism.

    Science.gov (United States)

    Kaland, Constantijn; Swerts, Marc; Krahmer, Emiel

    2013-09-01

    The present research investigates what drives the prosodic marking of contrastive information. For example, a typically developing speaker of a Germanic language like Dutch generally refers to a pink car as a "PINK car" (accented words in capitals) when a previously mentioned car was red. The main question addressed in this paper is whether contrastive intonation is produced with respect to the speaker's or (also) the listener's perspective on the preceding discourse. Furthermore, this research investigates the production of contrastive intonation by typically developing speakers and speakers with autism. The latter group is investigated because people with autism are argued to have difficulties accounting for another person's mental state and exhibit difficulties in the production and perception of accentuation and pitch range. To this end, utterances with contrastive intonation are elicited from both groups and analyzed in terms of function and form of prosody using production and perception measures. Contrary to expectations, typically developing speakers and speakers with autism produce functionally similar contrastive intonation as both groups account for both their own and their listener's perspective. However, typically developing speakers use a larger pitch range and are perceived as speaking more dynamically than speakers with autism, suggesting differences in their use of prosodic form.

  7. Compound nouns in spoken language production by speakers with aphasia compared to neurologically healthy speakers: an exploratory study.

    Science.gov (United States)

    Eiesland, Eli Anne; Lind, Marianne

    2012-03-01

    Compounds are words that are made up of at least two other words (lexemes), featuring lexical and syntactic characteristics and thus particularly interesting for the study of language processing. Most studies of compounds and language processing have been based on data from experimental single word production and comprehension tasks. To enhance the ecological validity of morphological processing research, data from other contexts, such as discourse production, need to be considered. This study investigates the production of nominal compounds in semi-spontaneous spoken texts by a group of speakers with fluent types of aphasia compared to a group of neurologically healthy speakers. The speakers with aphasia produce significantly fewer nominal compound types in their texts than the non-aphasic speakers, and the compounds they produce exhibit fewer different types of semantic relations than the compounds produced by the non-aphasic speakers. The results are discussed in relation to theories of language processing.

    Reilly, Kevin J; Spencer, Kristie A

    2013-01-01

    The current study investigated the processes responsible for selection of sounds and syllables during production of speech sequences in 10 adults with hypokinetic dysarthria from Parkinson's disease, five adults with ataxic dysarthria, and 14 healthy control speakers. Speech production data from a choice reaction time task were analyzed to evaluate the effects of sequence length and practice on speech sound sequencing. Speakers produced sequences that were between one and five syllables in length over five experimental runs of 60 trials each. In contrast to the healthy speakers, speakers with hypokinetic dysarthria demonstrated exaggerated sequence length effects for both inter-syllable intervals (ISIs) and speech error rates. Conversely, speakers with ataxic dysarthria failed to demonstrate a sequence length effect on ISIs and were also the only group that did not exhibit practice-related changes in ISIs and speech error rates over the five experimental runs. The exaggerated sequence length effects in the hypokinetic speakers with Parkinson's disease are consistent with an impairment of action selection during speech sequence production. The absent length effects observed in the speakers with ataxic dysarthria is consistent with previous findings that indicate a limited capacity to buffer speech sequences in advance of their execution. In addition, the lack of practice effects in these speakers suggests that learning-related improvements in the production rate and accuracy of speech sequences involves processing by structures of the cerebellum. Together, the current findings inform models of serial control for speech in healthy speakers and support the notion that sequencing deficits contribute to speech symptoms in speakers with hypokinetic or ataxic dysarthria. In addition, these findings indicate that speech sequencing is differentially impaired in hypokinetic and ataxic dysarthria.

    Full Text Available The current study investigated the processes responsible for selection of sounds and syllables during production of speech sequences in 10 adults with hypokinetic dysarthria from Parkinson’s disease, 5 adults with ataxic dysarthria, and 14 healthy control speakers. Speech production data from a choice reaction time task were analyzed to evaluate the effects of sequence length and practice on speech sound sequencing. Speakers produced sequences that were between one and five syllables in length over five experimental runs of 60 trials each. In contrast to the healthy speakers, speakers with hypokinetic dysarthria demonstrated exaggerated sequence length effects for both inter-syllable intervals (ISIs and speech error rates.

    Appointment reminders help parents deal with complex immunization schedules. Preferred content of text-message reminders has been identified for English-speakers. Spanish-speaking parents of children under three years old were recruited to develop Spanish text-message immunization reminders. Structured interviews included questions about demographic characteristics, use of technology, and willingness to receive text reminders. Each participant was assigned to one user-centered design (UCD) test: card sort, needs analysis or comprehension testing. Respondents (N=54) were female (70%) and averaged 27 years of age (SD=7). A card sort of 20 immunization-related statements resulted in identification of seven pieces of critical information, which were compiled into eight example texts. These texts were ranked in the needs assessment and the top two were assessed for comprehension. All participants were able to understand the content and describe intention to act. Utilizing UCD testing, Spanish-speakers identified short, specific text content that differed from preferred content of English-speaking parents.

    Full Text Available This article evaluates the performance of Extreme Learning Machine (ELM and Gaussian Mixture Model (GMM in the context of text independent Multi lingual speaker identification for recorded and synthesized speeches. The type and number of filters in the filter bank, number of samples in each frame of the speech signal and fusion of model scores play a vital role in speaker identification accuracy and are analyzed in this article. Extreme Learning Machine uses a single hidden layer feed forward neural network for multilingual speaker identification. The individual Gaussian components of GMM best represent speaker-dependent spectral shapes that are effective in speaker identity. Both the modeling techniques make use of Linear Predictive Residual Cepstral Coefficient (LPRCC, Mel Frequency Cepstral Coefficient (MFCC, Modified Mel Frequency Cepstral Coefficient (MMFCC and Bark Frequency Cepstral Coefficient (BFCC features to represent the speaker specific attributes of speech signals. Experimental results show that GMM outperforms ELM with speaker identification accuracy of 97.5% with frame size of 256 and frame shift of half of frame size and filter bank size of 40.

    To study the independence of gesture and verbal language production. The authors assessed whether gesture can be semantically compensatory in cases of verbal language impairment and whether speakers with aphasia and control participants use similar depiction techniques in gesture. The informativeness of gesture was assessed in 3 forced-choice studies, in which raters assessed the topic of the speaker's message in video clips of 13 speakers with moderate aphasia and 12 speakers with severe aphasia, who were performing a communication test (the Scenario Test). Both groups were compared and contrasted with 17 control participants, who either were or were not allowed to communicate verbally. In addition, the representation techniques used in gesture were analyzed. Gestures produced by speakers with more severe aphasia were less informative than those by speakers with moderate aphasia, yet they were not necessarily uninformative. Speakers with more severe aphasia also tended to use fewer representation techniques (mostly relying on outlining gestures) in co-speech gesture than control participants, who were asked to use gesture instead of speech. It is important to note that limb apraxia may be a mediating factor here. These results suggest that in aphasia, gesture tends to degrade with verbal language. This may imply that the processes underlying verbal language and co-speech gesture production, although partly separate, are closely linked.

    2015-08-01

    Atypical duration of speech segments can signal a speech disorder. In this study, we examined variation in vowel duration in African American English (AAE) relative to White American English (WAE) speakers living in the same dialect region in the South to characterize the nature of systematic variation between the 2 groups. The goal was to establish whether segmental durations in minority populations differ from the well-established patterns in mainstream populations. Participants were 32 AAE and 32 WAE speakers differing in age who, in their childhood, attended either segregated (older speakers) or integrated (younger speakers) public schools. Speech materials consisted of 14 vowels produced in hVd-frame. AAE vowels were significantly longer than WAE vowels. Vowel duration did not differ as a function of age. The temporal tense-lax contrast was minimized for AAE relative to WAE. Vowels produced by females were significantly longer than vowels produced by males for both AAE and WAE. African American speakers should be expected to produce longer vowels relative to White speakers in a common geographic area. These longer durations are not deviant but represent a typical feature of AAE. This finding has clinical importance in guiding assessments of speech disorders in AAE speakers.

    Voice quality provides information about the anatomical characteristics of the speaker. The patterns of somatotype and body composition can provide essential knowledge to characterize the individuality of voice quality. The aim of this study was to verify if there were significant differences in somatotype and body composition between normal and dysphonic speakers. Cross-sectional study. Anthropometric measurements were taken of a sample of 72 adult participants (40 normal speakers and 32 dysphonic speakers) according to International Society for the Advancement of Kinanthropometry standards, which allowed the calculation of endomorphism, mesomorphism, ectomorphism components, body density, body mass index, fat mass, percentage fat, and fat-free mass. Perception and acoustic evaluations as well as nasoendoscopy were used to assign speakers into normal or dysphonic groups. There were no significant differences between normal and dysphonic speakers in the mean somatotype attitudinal distance and somatotype dispersion distance (in spite of marginally significant differences [P speakers.

    Manyspeakers with cleft palate develop atypical consonant productions, especially for pressure consonants such as plosives, fricatives, and affricates. The present study investigated the nature of nasal sound errors. The participants were eight female and three male speakers with cleft palate between the ages of 6 to 20. Speakers were audio-recorded, and midsagittal tongue movement was captured with ultrasound. The speakers repeated vowel-consonant-vowel with the vowels /α/, /i/, and /u/ and the alveolar and velar nasal consonants /n/ and //. The productions were reviewed by three listeners. The participants showed a variety of different placement errors and insertions of plosives, as well as liquid productions. There was considerable error variability between and within speakers, often related to the different vowel contexts. Three speakers co-produced click sounds. The study demonstrated the wide variety of sound errors that some speakers with cleft palate may demonstrate for nasal sounds. Nasal sounds, ideally in different vowel contexts, should be included in articulation screenings for speakers with cleft palate, perhaps more than is currently the case.

    Full Text Available In this article, we show some of the meanings in which Daniel Dennett uses the term intentionality, in an attempt to establish to it the quality of key concept for understanding the mind, namely consciousness. By analyzing the American thinker’s ideas, we consider that in all of them an intentionality system can be identified, which includes the approaches and different names that he dedicates to this concept. Qualitative differences in the discourse about intentionality can open the way of the approach of intentionality from an evolutionary perspective, indicating the changes over time. The intentionality system is a proposal for understanding Dennett’s thinking in a coherent paradigm.

    2010-01-01

    Speakers who use an electrolarynx following a total laryngectomy no longer require pulmonary support for speech. Subsequently, chest wall movements may be affected; however, chest wall movements in these speakers are not well defined. The purpose of this investigation was to evaluate speech breathing in speakers who use an electrolarynx during speech and reading tasks. Six speakers who use an electrolarynx underwent an evaluation of chest wall kinematics (e.g., chest wall movements, temporal characteristics of chest wall movement), lung volumes, temporal measures of speech, and the interaction of linguistic influences on ventilation. Results of the present study were compared to previous reports in speakers who use an electrolarynx, as well as to previous reports in typical speakers. There were no significant differences in lung volumes used and the general movement of the chest wall by task; however, there were differences of note in the temporal aspects of chest wall configuration when compared to previous reports in both typical speakers and speakers who use an electrolarynx. These differences were related to timing and posturing of the chest wall. The lack of differences in lung volumes and chest wall movements by task indicates that neither reading nor spontaneous speech exerts a greater influence on speech breathing; however, the temporal and posturing results suggest the possibility of a decoupling of the respiratory system from speech following a total laryngectomy and subsequent alaryngeal speech rehabilitation. The reader will be able to understand and describe: (1) The primary differences in speech breathing across alaryngeal speech options; (2) how speech breathing specifically differs (i.e., lung volumes and chest wall movements) in speakers who use an electrolarynx; (3) How the coupling of speech and respiration is altered when pulmonary air is no longer used for speech.

  13. On how the brain decodes vocal cues about speaker confidence.

    Science.gov (United States)

    Jiang, Xiaoming; Pell, Marc D

    2015-05-01

    In speech communication, listeners must accurately decode vocal cues that refer to the speaker's mental state, such as their confidence or 'feeling of knowing'. However, the time course and neural mechanisms associated with online inferences about speaker confidence are unclear. Here, we used event-related potentials (ERPs) to examine the temporal neural dynamics underlying a listener's ability to infer speaker confidence from vocal cues during speech processing. We recorded listeners' real-time brain responses while they evaluated statements wherein the speaker's tone of voice conveyed one of three levels of confidence (confident, close-to-confident, unconfident) or were spoken in a neutral manner. Neural responses time-locked to event onset show that the perceived level of speaker confidence could be differentiated at distinct time points during speech processing: unconfident expressions elicited a weaker P2 than all other expressions of confidence (or neutral-intending utterances), whereas close-to-confident expressions elicited a reduced negative response in the 330-500 msec and 550-740 msec time window. Neutral-intending expressions, which were also perceived as relatively confident, elicited a more delayed, larger sustained positivity than all other expressions in the 980-1270 msec window for this task. These findings provide the first piece of evidence of how quickly the brain responds to vocal cues signifying the extent of a speaker's confidence during online speech comprehension; first, a rough dissociation between unconfident and confident voices occurs as early as 200 msec after speech onset. At a later stage, further differentiation of the exact level of speaker confidence (i.e., close-to-confident, very confident) is evaluated via an inferential system to determine the speaker's meaning under current task settings. These findings extend three-stage models of how vocal emotion cues are processed in speech comprehension (e.g., Schirmer & Kotz, 2006) by

    This work addresses the evaluation of the human and the automatic speaker recognition performances under different channel distortions caused by bandwidth limitation, codecs, and electro-acoustic user interfaces, among other impairments. Its main contribution is the demonstration of the benefits of communication channels of extended bandwidth, together with an insight into how speaker-specific characteristics of speech are preserved through different transmissions. It provides sufficient motivation for considering speaker recognition as a criterion for the migration from narrowband to enhanced bandwidths, such as wideband and super-wideband.

  15. STATISTICAL FEATURE OF PITCH FREQUENCY DISTRIBUTIONS FOR ROBUST SPEAKER IDENTIFICATION

    Zhang Linghua; Zheng Baoyu; Yang Zhen

    2005-01-01

    This letter proposes an effective and robust speech feature extraction method based on statistical analysis of Pitch Frequency Distributions (PFD) for speaker identification. Compared with the conventional cepstrum, PFD is relatively insensitive to Additive White Gaussian Noise (AWGN), but it does not show good performance for speaker identification, even if under clean environments. To compensate this shortcoming, PFD and conventional cepstrum are combined to make the ultimate decision, instead of simply taking one kind of features into account.Experimental results indicate that the hybrid approach can give outstanding improvement for text-independent speaker identification under noisy environments corrupted by AWGN.

  17. Intention understanding in autism.

    Directory of Open Access Journals (Sweden)

    Sonia Boria

    Full Text Available When we observe a motor act (e.g. grasping a cup done by another individual, we extract, according to how the motor act is performed and its context, two types of information: the goal (grasping and the intention underlying it (e.g. grasping for drinking. Here we examined whether children with autistic spectrum disorder (ASD are able to understand these two aspects of motor acts. Two experiments were carried out. In the first, one group of high-functioning children with ASD and one of typically developing (TD children were presented with pictures showing hand-object interactions and asked what the individual was doing and why. In half of the "why" trials the observed grip was congruent with the function of the object ("why-use" trials, in the other half it corresponded to the grip typically used to move that object ("why-place" trials. The results showed that children with ASD have no difficulties in reporting the goals of individual motor acts. In contrast they made several errors in the why task with all errors occurring in the "why-place" trials. In the second experiment the same two groups of children saw pictures showing a hand-grip congruent with the object use, but within a context suggesting either the use of the object or its placement into a container. Here children with ASD performed as TD children, correctly indicating the agent's intention. In conclusion, our data show that understanding others' intentions can occur in two ways: by relying on motor information derived from the hand-object interaction, and by using functional information derived from the object's standard use. Children with ASD have no deficit in the second type of understanding, while they have difficulties in understanding others' intentions when they have to rely exclusively on motor cues.

  19. Presentation skills for the reluctant speaker.

    Science.gov (United States)

    Garon, J E

    1999-01-01

    Presentation skills are vital to clinical systems managers. This article covers four steps to successful presentations: 1) tailoring for an audience, 2) organizing a presentation, 3) mastering presentation techniques, and 4) creating effective visual aids. Tailoring for the audience entails learning about the audience and matching the presentation to their knowledge, educational level, and interests. Techniques to curry favor with an audience include: establishing common ground, relating through universal experiences, and pushing "hot buttons." Tasks involved in organizing the presentation for maximum audience interest begin with arranging the key points in a transparent organizational scheme. Audience attention is sustained using "hooks," such as graphics, anecdotes, humor, and quotations. Basic presentation techniques include appropriate rehearsal, effective eye contact with an audience, and anxiety-reducing strategies. Visual aids include flip charts, slides, transparencies, and computer presentations. Criteria for selecting the type of visual aids are delineated based on audience size and type of presentation, along with respective advantages and disadvantages. The golden rule for presentations is "Never show a slide for which you have to apologize." Rules to maximize visibility and effectiveness, including use of standard templates, sans serif fonts, dark backgrounds with light letters, mixed cases, and effective graphics, ensure that slides or projected computer images are clear and professional. Taken together, these strategies will enhance the delivery of the presentation and decrease the speaker's anxiety.

  20. English vowel learning by speakers of Mandarin

    Thomson, Ron I.

    2005-04-01

    One of the most influential models of second language (L2) speech perception and production [Flege, Speech Perception and Linguistic Experience (York, Baltimore, 1995) pp. 233-277] argues that during initial stages of L2 acquisition, perceptual categories sharing the same or nearly the same acoustic space as first language (L1) categories will be processed as members of that L1 category. Previous research has generally been limited to testing these claims on binary L2 contrasts, rather than larger portions of the perceptual space. This study examines the development of 10 English vowel categories by 20 Mandarin L1 learners of English. Imitation of English vowel stimuli by these learners, at 6 data collection points over the course of one year, were recorded. Using a statistical pattern recognition model, these productions were then assessed against native speaker norms. The degree to which the learners' perception/production shifted toward the target English vowels and the degree to which they matched L1 categories in ways predicted by theoretical models are discussed. The results of this experiment suggest that previous claims about perceptual assimilation of L2 categories to L1 categories may be too strong.

    Person identification, especially in critical environments, has always been a subject of great interest. However, it has gained a new dimension in a world threatened by a new kind of terrorism that uses social networks (e.g., YouTube) to broadcast its message. In this new scenario, classical identification methods (such as fingerprints or face recognition) have been forcedly replaced by alternative biometric characteristics such as voice, as sometimes this is the only feature available. The present study benefits from the advances achieved during last years in understanding and modeling voice production. The paper hypothesizes that a gender-dependent characterization of speakers combined with the use of a set of features derived from the components, resulting from the deconstruction of the voice into its glottal source and vocal tract estimates, will enhance recognition rates when compared to classical approaches. A general description about the main hypothesis and the methodology followed to extract the gender-dependent extended biometric parameters is given. Experimental validation is carried out both on a highly controlled acoustic condition database, and on a mobile phone network recorded under non-controlled acoustic conditions.

    Full Text Available Inter-language pragmatics (ILP and politeness have long been of considerable significance in language learning research. The present study investigated the notion of polite and impolite requests among Iranian EFL learners. The participants, 30 MA students of English, responded to a discourse completion task (DCT realizing the speech act of request and the utterances were analyzed in three phases. First, the request strategies and politeness strategies were identified based on Blum-Kulka, House and Kasper's (1989b taxonomy of request strategies and Brown and Levinson's (1987 politeness theory, respectively. Next, a sample of 149 request utterances were evaluated by two native English speakers in terms of politeness on a three-point politeness Likert scale as such: 1Polite, 2Partially polite and 3Impolite. Finally, the request utterances were qualitatively analyzed. The results of the first phase indicated that the most frequent request strategies were mood-derivable, query-preparatory and strong hints and the most frequent politeness strategies negative and positive politeness. The native speakers' evaluation showed that only 21.5% (32 utterances of the requests were rated as polite with partially polite and impolite request constituting 58% and 20.5%, respectively. The findings also demonstrated that there are both conformities to and deviations from the native speaker norms in the realization of the speech act of request by Iranian EFL learners. The study highlighted the need for instructional intervention in pragmatics in classroom settings. Furthermore, the results showed that there are serious potential of breakdowns in Iranian EFL learners' intercultural communication, hence the need for explicit teaching of pragmatics.

In the European Union member states, scholars have analysed the use of lay judges in criminal cases. However, little is known about lay participation in civil justice. The paper introduces commonly cited reasons to have lay judges as well as the principal forms of lay participation and then surveys the EU countries for its implementation in civil cases. Mixed tribunals, involving lay judges under the leadership of a professional judge, are relatively frequent. Several countries have special labour courts or commercial courts with lay members and others have single lay judges, or all-lay judge panels. Roughly a third of the 28 EU member states have no lay participation in civil justice but only three of those have no lay judges in any branch of the courts. Almost all the reasons for including lay decision makers are served somehow by the existing forms, including providing different experiences and perhaps expert knowledge. The article concludes, citing non-EU states and lay participation in criminal and administrative courts as further evidence, that lay judges in one form or another are an element of European legal systems.

    Full Text Available Gaussian mixture models with universal background model (GMM-UBM and vector quantization with universal background model (VQ-UBM are the two well-known classifiers used for speaker verification. Generally, UBM is trained with many hours of speech from a large pool of different speakers. In this study, we analyze the effect of data duration used to train UBM on text-independent speaker verification performance using GMM-UBM and VQ-UBM modeling techniques. Experiments carried out NIST 2002 speaker recognition evaluation (SRE corpus show that background data duration to train UBM has small impact on recognition performance for GMM-UBM and VQ-UBM classifiers.

    The speaker adaptation is an effective means of improving the performance of a speech recognition system,and it can be divided into supervised or unsupervised speaker adaptation.In this paper a kind of confidence measure based on the word lattice structure is proposed and is used for the supervised and unsupervised speaker adaptation.The reliability of the recognition results can be evaluated by the confidence measure,and the uncertain parts in the recognition results can be removed or be given smaller weights in the speaker adaptation process.The experiments show that the confidence can effectively eliminate the suspicious speech and improve the performance of the supervised and unsupervised adaptation considerably.The performance difference between the supervised and unsupervised adaptation is reduced by using the confidence measure based on the word lattice structure.

  11. Electrophysiology of subject-verb agreement mediated by speakers' gender.

    Hanulíková, Adriana; Carreiras, Manuel

    2015-01-01

    An important property of speech is that it explicitly conveys features of a speaker's identity such as age or gender. This event-related potential (ERP) study examined the effects of social information provided by a speaker's gender, i.e., the conceptual representation of gender, on subject-verb agreement. Despite numerous studies on agreement, little is known about syntactic computations generated by speaker characteristics extracted from the acoustic signal. Slovak is well suited to investigate this issue because it is a morphologically rich language in which agreement involves features for number, case, and gender. Grammaticality of a sentence can be evaluated by checking a speaker's gender as conveyed by his/her voice. We examined how conceptual information about speaker gender, which is not syntactic but rather social and pragmatic in nature, is interpreted for the computation of agreement patterns. ERP responses to verbs disagreeing with the speaker's gender (e.g., a sentence including a masculine verbal inflection spoken by a female person 'the neighbors were upset because I (∗)stoleMASC plums') elicited a larger early posterior negativity compared to correct sentences. When the agreement was purely syntactic and did not depend on the speaker's gender, a disagreement between a formally marked subject and the verb inflection (e.g., the womanFEM (∗)stoleMASC plums) resulted in a larger P600 preceded by a larger anterior negativity compared to the control sentences. This result is in line with proposals according to which the recruitment of non-syntactic information such as the gender of the speaker results in N400-like effects, while formally marked syntactic features lead to structural integration as reflected in a LAN/P600 complex.

The specific objective of the survey presented here, however, was to build up the target picture with some of the features of the ideal example of the house category, such as the shape of the house, the key materials its principal structural elements (foundations, walls, a roof are made of, the number of residential units in the house and the type of the household that occupies it, the number of the house levels, the minimum of its interior spatial components and their functions, the types of systemic parts in the house, the status and position of the house relative to surround­ing buildings, etc. Also, taking into consideration that the demographic profiles of the survey participants reflected various cultural backgrounds (which significantly influence the formation of mental images of a typical sample of the category, the survey aimed to compare the similarities and differences between the 'English' and the 'Serbian' typical house, that is the features assigned to a typical house by most of the surveyed representa­tives of Anglo-American and by those of Serbian culture. Judging exclusively by the features observed and the results obtained, the study concludes that the 'English' and the 'Serbian' typical house look very similar in many aspect and that the two different cultures are not as distant as they may seem.

  15. FPGA Implementation for GMM-Based Speaker Identification

    Full Text Available In today's society, highly accurate personal identification systems are required. Passwords or pin numbers can be forgotten or forged and are no longer considered to offer a high level of security. The use of biological features, biometrics, is becoming widely accepted as the next level for security systems. Biometric-based speaker identification is a method of identifying persons from their voice. Speaker-specific characteristics exist in speech signals due to different speakers having different resonances of the vocal tract. These differences can be exploited by extracting feature vectors such as Mel-Frequency Cepstral Coefficients (MFCCs from the speech signal. A well-known statistical modelling process, the Gaussian Mixture Model (GMM, then models the distribution of each speaker's MFCCs in a multidimensional acoustic space. The GMM-based speaker identification system has features that make it promising for hardware acceleration. This paper describes the hardware implementation for classification of a text-independent GMM-based speaker identification system. The aim was to produce a system that can perform simultaneous identification of large numbers of voice streams in real time. This has important potential applications in security and in automated call centre applications. A speedup factor of ninety was achieved compared to a software implementation on a standard PC.

    2014-12-01

    In this investigation, the construct of perceptual similarity was explored in the dysarthrias. Specifically, we employed an auditory free-classification task to determine whether listeners could cluster speakers by perceptual similarity, whether the clusters mapped to acoustic metrics, and whether the clusters were constrained by dysarthria subtype diagnosis. Twenty-three listeners blinded to speakers' medical and dysarthria subtype diagnoses participated. The task was to group together (drag and drop) the icons corresponding to 33 speakers with dysarthria on the basis of how similar they sounded. Cluster analysis and multidimensional scaling (MDS) modeled the perceptual dimensions underlying similarity. Acoustic metrics and perceptual judgments were used in correlation analyses to facilitate interpretation of the derived dimensions. Six clusters of similar-sounding speakers and 3 perceptual dimensions underlying similarity were revealed. The clusters of similar-sounding speakers were not constrained by dysarthria subtype diagnosis. The 3 perceptual dimensions revealed by MDS were correlated with metrics for articulation rate, intelligibility, and vocal quality, respectively. This study shows (a) feasibility of a free-classification approach for studying perceptual similarity in dysarthria, (b) correspondence between acoustic and perceptual metrics to clusters of similar-sounding speakers, and (c) similarity judgments transcended dysarthria subtype diagnosis.

  17. Intonation and gender perception: applications for transgender speakers.

    2014-03-01

    Intonation is commonly addressed in voice and communication feminization therapy, yet empirical evidence of gender differences for intonation is scarce and rarely do studies examine how it relates to gender perception of transgender speakers. This study examined intonation of 12 males, 12 females, six female-to-male, and 14 male-to-female transgender speakers describing a Norman Rockwell image. Several intonation measures were compared between biological gender groups, between perceived gender groups, and between male-to-female (MTF) speakers who were perceived as male, female, or ambiguous gender. Speakers with a larger percentage of utterances with upward intonation and a larger utterance semitone range were perceived as female by listeners, despite no significant differences between the actual intonation of the four gender groups. MTF speakers who do not pass as female appear to use less upward and more downward intonations than female and passing MTF speakers. Intonation has potential for use in transgender communication therapy because it can influence perception to some degree. Copyright © 2014 The Voice Foundation. Published by Mosby, Inc.

    2008-09-01

    The ability to interpret vocal (prosodic) cues during social interactions can be disrupted by Parkinson's disease, with notable effects on how emotions are understood from speech. This study investigated whether PD patients who have emotional prosody deficits exhibit further difficulties decoding the attitude of a speaker from prosody. Vocally inflected but semantically nonsensical 'pseudo-utterances' were presented to listener groups with and without PD in two separate rating tasks. Task I required participants to rate how confident a speaker sounded from their voice and Task 2 required listeners to rate how polite the speaker sounded for a comparable set of pseudo-utterances. The results showed that PD patients were significantly less able than HC participants to use prosodic cues to differentiate intended levels of speaker confidence in speech, although the patients could accurately detect the politelimpolite attitude of the speaker from prosody in most cases. Our data suggest that many PD patients fail to use vocal cues to effectively infer a speaker's emotions as well as certain attitudes in speech such as confidence, consistent with the idea that the basal ganglia play a role in the meaningful processing of prosodic sequences in spoken language (Pell & Leonard, 2003).

    This study examined the relationship (1) between acoustic vowel space and the corresponding tongue kinematic vowel space and (2) between formant frequencies (F1 and F2) and tongue x-y coordinates for the same time sampling point. Thirteen healthy female adults participated in this study. Electromagnetic articulography and synchronized acoustic recordings were utilized to obtain vowel acoustic and tongue kinematic data across ten speech tasks. Intra-speaker analyses showed that for 10 of the 13 speakers the acoustic vowel space was moderately to highly correlated with tongue kinematic vowel space; much weaker correlations were obtained for inter-speaker analyses. Correlations of individual formants with tongue positions showed that F1 varied strongly with tongue position variations in the y dimension, whereas F2 was correlated in equal magnitude with variations in the x and y positions. For within-speaker analyses, the size of the acoustic vowel space is likely to provide a reasonable inference of size of the tongue working space for most speakers; unfortunately there is no a priori, obvious way to identify the speakers for whom the covariation is not significant. A second conclusion is that F1 variations reflect tongue height, but F2 is a much more complex reflection of tongue variation in both dimensions.

    Practical abilities are important for students from majors including Computer Science and Engineering, and Electrical Engineering. Along with the popularity of ACM International Collegiate Programming Contest (ACM/ICPC) and other programming contests, online judge (OJ) websites achieve rapid development, thus providing a new kind of programming practice, i.e. online practice. Due to fair and timely feedback results from OJ websites, online practice outperforms traditional programming practice. In order to promote students' practical abilities in programming and algorithm designing, this article presents a novel teaching idea, online judge & practice oriented teaching (OJPOT). OJPOT is applied to Programming Foundation course. OJPOT cultivates students' practical abilities through various kinds of programming practice, such as programming contests, online practice and course project. To verify the effectiveness of this novel teaching idea, this study conducts empirical research. The experimental results show that OJPOT works effectively in enhancing students' practical abilities compared with the traditional teaching idea.

    For lower efficiency and poorer reliability in programming training and competition by currently artificial judgment, design an Online Automatic Judging (referred to as OAJ) System. The OAJ system including the sandbox judging side and Web side, realizes functions of automatically compiling and running the tested codes, and generating evaluation scores and corresponding reports. To prevent malicious codes from damaging system, the OAJ system utilizes sandbox, ensuring the safety of the system. The OAJ system uses thread pools to achieve parallel test, and adopt database optimization mechanism, such as horizontal split table, to improve the system performance and resources utilization rate. The test results show that the system has high performance, high reliability, high stability and excellent extensibility.

    A Federal judge has refused to overturn or reduce a jury's $125,000 award to a Southeastern Pennsylvania Transportation Authority (SEPTA) employee who said his privacy was invaded when his superiors learned he was taking an AIDS medication. The employee, known as John Doe, charged that Judith Pierce, the chief administrative officer of SEPTA, looked at the records of the agency's prescription drug plan to confirm her suspicions that he had HIV. Pierce, who claimed drug report review was part of her job in controlling costs, contended that she wanted to make sure the plan's new administrator, Rite-Aid Corp., was charging the right prices for prescriptions. The judge agreed with the jury that Pierce went far beyond her role as auditor of the drug plan when she asked Rite-Aid to link individuals' names to specific prescriptions and then informed Doe's supervisor, associate, and another employee about Doe's AIDS medication.

    Intentionality is an essentially mental, essentially occurrent, and essentially experiential (conscious) phenomenon. Any attempt to characterize intentionality that detaches it from conscious experience faces two insuperable problems. First, it is obliged to concede that almost everything (if not everything) has intentionality—all the way down to subatomic particles. Second, it has the consequence that everything that has intentionality has far too much of it—perhaps an infinite amount. The k...

    2015-01-01

    The increasing number of casting shows and talent contests in the media over the past years suggests a public interest in rating the quality of vocal performances. In many of these formats, laymen alongside music experts act as judges. Whereas experts' judgments are considered objective and reliable when it comes to evaluating singing voice, little is known about laymen's ability to evaluate peers. On the one hand, layman listeners-who by definition did not have any formal training or regular musical practice-are known to have internalized the musical rules on which singing accuracy is based. On the other hand, layman listeners' judgment of their own vocal skills is highly inaccurate. Also, when compared with that of music experts, their level of competence in pitch perception has proven limited. The present study investigates laypersons' ability to objectively evaluate melodies performed by untrained singers. For this purpose, laymen listeners were asked to judge sung melodies. The results were compared with those of music experts who had performed the same task in a previous study. Interestingly, the findings show a high objectivity and reliability in layman listeners. Whereas both the laymen's and experts' definition of pitch accuracy overlap, differences regarding the musical criteria employed in the rating task were evident. The findings suggest that the effect of expertise is circumscribed and limited and supports the view that laypersons make trustworthy judges when evaluating the pitch accuracy of untrained singers.

    2014-01-01

    Full Text Available This article touches upon the different ways of specialization of courts and judges that exist under the legislation of the Russian Federation. The lack of a unified and circumspect approach is noted. The formation of specialized courts, according to the national legislation, takes the form of their establishing within the existing subsystems of regular and arbitration courts. As for the specialization of judges, it is more diversified and is presented by either creation of separate types of procedure (special proceedings, proceedings on cases arising from public relations and some other, or by introduction of special rules on jurisdiction that establish competence of specific courts to consider cases of a particular category: on the compensation for the excessive time taken to consider a case, on the adoption of a child by a foreign national and others.An analysis of existing literature on the issue in question shows that Russian scholars support the idea of judges’ specialization. Against specialization of courts the following arguments are brought: significant material costs, not being in accordance with the small number of cases decided by specialized courts; problems with access to justice; and the necessity to give special training to narrowly specialized judges.

    Full Text Available Functional brain imaging studies have improved our knowledge of the neural localization of language functions and the functional recovery after a lesion. However, the neural correlates of agrammatic symptoms in aphasia remain largely unknown. The present fMRI study examined the neural correlates of morpho-syntactic encoding and agrammatic errors in continuous language production by combining three approaches. First, the neural mechanisms underlying natural morpho-syntactic processing in a picture description task were analyzed in 15 healthy speakers. Second, agrammatic-like speech behavior was induced in the same group of healthy speakers to study the underlying functional processes by limiting the utterance length. In a third approach, five agrammatic participants performed the picture description task to gain insights in the neural correlates of agrammatism and the functional reorganization of language processing after stroke. In all approaches, utterances were analyzed for syntactic completeness, complexity and morphology. Event-related data analysis was conducted by defining every clause-like unit (CLU as an event with its onset-time and duration. Agrammatic and correct CLUs were contrasted. Due to the small sample size as well as heterogeneous lesion sizes and sites with lesion foci in the insula lobe, inferior frontal, superior temporal and inferior parietal areas the activation patterns in the agrammatic speakers were analyzed on a single subject level. In the group of healthy speakers, posterior temporal and inferior parietal areas were associated with greater morpho-syntactic demands in complete and complex CLUs. The intentional manipulation of morpho-syntactic structures and the omission of function words were associated with additional inferior frontal activation. Overall, the results revealed that the investigation of the neural correlates of agrammatic language production can be reasonably conducted with an overt language production

    Dysprosody is a common feature in speakers with hypokinetic dysarthria. However, speech prosody varies across different types of speech materials. This raises the question of what is the most appropriate speech material for the evaluation of dysprosody. To characterize the prosodic impairment in Cantonese speakers with hypokinetic dysarthria associated with Parkinson's disease, and to determine the effect of different types of speech stimuli on the perceptual rating of prosody. Speech data in the form of sentence reading, passage reading, and monologue were collected from ten Cantonese speakers with Parkinson's disease. Perceptual analysis was conducted on ten prosodic parameters to evaluate five dimensions of prosody, based on a theoretical framework: pitch, loudness, duration, voice quality, and degree of reduction. The results showed that the most severely affected prosodic parameters were monopitch, harsh voice, and monoloudness, followed by breathy voice and prolonged interval. Differences were noted between speakers with mild and moderate dysprosody. No statistically significant differences were found between the three types of stimuli. However, qualitative analysis revealed noticeable differences between the three stimuli in two speakers. The prosodic profile of Cantonese speakers with hypokinetic dysarthria is similar to those of other languages (for example, English). The involvement of two new dimensions in the definition of prosody (voice quality and degree of reduction) provides additional insight in differentiating patients with mild and moderate dysarthria. Further investigation on the use of speech materials in the clinical evaluation of speech prosody in speakers with dysarthria is needed, as no single task was found to represent a patient's performance under all circumstances.

  15. Intention seekers: conspiracist ideation and biased attributions of intentionality.

    Directory of Open Access Journals (Sweden)

    Robert Brotherton

    Full Text Available Conspiracist beliefs are widespread and potentially hazardous. A growing body of research suggests that cognitive biases may play a role in endorsement of conspiracy theories. The current research examines the novel hypothesis that individuals who are biased towards inferring intentional explanations for ambiguous actions are more likely to endorse conspiracy theories, which portray events as the exclusive product of intentional agency. Study 1 replicated a previously observed relationship between conspiracist ideation and individual differences in anthropomorphisation. Studies 2 and 3 report a relationship between conspiracism and inferences of intentionality for imagined ambiguous events. Additionally, Study 3 again found conspiracist ideation to be predicted by individual differences in anthropomorphism. Contrary to expectations, however, the relationship was not mediated by the intentionality bias. The findings are discussed in terms of a domain-general intentionality bias making conspiracy theories appear particularly plausible. Alternative explanations are suggested for the association between conspiracism and anthropomorphism.

  16. Noise Reduction with Microphone Arrays for Speaker Identification

    Energy Technology Data Exchange (ETDEWEB)

    Cohen, Z

    2011-12-22

    Reducing acoustic noise in audio recordings is an ongoing problem that plagues many applications. This noise is hard to reduce because of interfering sources and non-stationary behavior of the overall background noise. Many single channel noise reduction algorithms exist but are limited in that the more the noise is reduced; the more the signal of interest is distorted due to the fact that the signal and noise overlap in frequency. Specifically acoustic background noise causes problems in the area of speaker identification. Recording a speaker in the presence of acoustic noise ultimately limits the performance and confidence of speaker identification algorithms. In situations where it is impossible to control the environment where the speech sample is taken, noise reduction filtering algorithms need to be developed to clean the recorded speech of background noise. Because single channel noise reduction algorithms would distort the speech signal, the overall challenge of this project was to see if spatial information provided by microphone arrays could be exploited to aid in speaker identification. The goals are: (1) Test the feasibility of using microphone arrays to reduce background noise in speech recordings; (2) Characterize and compare different multichannel noise reduction algorithms; (3) Provide recommendations for using these multichannel algorithms; and (4) Ultimately answer the question - Can the use of microphone arrays aid in speaker identification?

  17. Direct Speaker Gaze Promotes Trust in Truth-Ambiguous Statements.

    A speaker's gaze behaviour can provide perceivers with a multitude of cues which are relevant for communication, thus constituting an important non-verbal interaction channel. The present study investigated whether direct eye gaze of a speaker affects the likelihood of listeners believing truth-ambiguous statements. Participants were presented with videos in which a speaker produced such statements with either direct or averted gaze. The statements were selected through a rating study to ensure that participants were unlikely to know a-priori whether they were true or not (e.g., "sniffer dogs cannot smell the difference between identical twins"). Participants indicated in a forced-choice task whether or not they believed each statement. We found that participants were more likely to believe statements by a speaker looking at them directly, compared to a speaker with averted gaze. Moreover, when participants disagreed with a statement, they were slower to do so when the statement was uttered with direct (compared to averted) gaze, suggesting that the process of rejecting a statement as untrue may be inhibited when that statement is accompanied by direct gaze.

    This study examined acoustic variation of vowels within speakers across speech tasks. The overarching goal of the study was to understand within-speaker variation as one index of the range of normal speech motor behavior for American English vowels. Ten male speakers of American English performed four speech tasks including citation form sentence reading with a clear-speech style (clear-speech), citation form sentence reading (citation), passage reading (reading), and conversational speech (conversation). Eight monophthong vowels in a variety of consonant contexts were studied. Clear-speech was operationally defined as the reference point for describing variation. Acoustic measures associated with the conventions of vowel targets were obtained and examined. These included temporal midpoint formant frequencies for the first three formants (F1, F2, and F3) and the derived Euclidean distances in the F1-F2 and F2-F3 planes. Results indicated that reduction toward the center of the F1-F2 and F2-F3 planes increased in magnitude across the tasks in the order of clear-speech, citation, reading, and conversation. The cross-task variation was comparable for all speakers despite fine-grained individual differences. The characteristics of systematic within-speaker acoustic variation across tasks have potential implications for the understanding of the mechanisms of speech motor control and motor speech disorders.

  19. Studies of Chinese speakers with dysarthria: informing theoretical models.

    Whitehill, Tara L

    2010-01-01

    Most theoretical models of dysarthria have been developed based on research using individuals speaking English or other Indo-European languages. Studies of individuals with dysarthria speaking other languages can allow investigation into the universality of such models, and the interplay between language-specific and language-universal aspects of dysarthria. In this article, studies of Cantonese- and Mandarin-Chinese speakers with dysarthria are reviewed. The studies focused on 2 groups of speakers: those with cerebral palsy and those with Parkinson's disease. Key findings are compared with similar studies of English speakers. Since Chinese is tonal in nature, the impact of dysarthria on lexical tone has received considerable attention in the literature. The relationship between tone [which involves fundamental frequency (F(0)) control at the syllable level] and intonation (involving F(0) control at the sentential level) has received more recent attention. Many findings for Chinese speakers with dysarthria support earlier findings for English speakers, thus affirming the language-universal aspect of dysarthria. However, certain differences, which can be attributed to the distinct phonologies of Cantonese and Mandarin, highlight the language-specific aspects of the condition.

    This study investigated pitch perception and production in speech and music in individuals with congenital amusia (a disorder of musical pitch processing) who are native speakers of Cantonese, a tone language with a highly complex tonal system. Sixteen Cantonese-speaking congenital amusics and 16 controls performed a set of lexical tone perception, production, singing, and psychophysical pitch threshold tasks. Their tone production accuracy and singing proficiency were subsequently judged by independent listeners, and subjected to acoustic analyses. Relative to controls, amusics showed impaired discrimination of lexical tones in both speech and non-speech conditions. They also received lower ratings for singing proficiency, producing larger pitch interval deviations and making more pitch interval errors compared to controls. Demonstrating higher pitch direction identification thresholds than controls for both speech syllables and piano tones, amusics nevertheless produced native lexical tones with comparable pitch trajectories and intelligibility as controls. Significant correlations were found between pitch threshold and lexical tone perception, music perception and production, but not between lexical tone perception and production for amusics. These findings provide further evidence that congenital amusia is a domain-general language-independent pitch-processing deficit that is associated with severely impaired music perception and production, mildly impaired speech perception, and largely intact speech production.

  12. The impact of judges' perceptions of credibility in fibromyalgia claims.

    Science.gov (United States)

    Le Page, Judy A; Iverson, Grant L; Collins, Peter

    2008-01-01

    Fibromyalgia (FM) is a confusing and controversial diagnosis, characterized by widespread pain and tenderness at specific anatomical sites. The cause of this syndrome is unknown, and the course of the condition is difficult to predict. Without a known cause, predictable course, or effective treatment, it is not surprising that FM is a contentious diagnosis from a medical perspective, as well as a civil litigation and disability insurance industry perspective. The purpose of this study was to investigate judges' perceptions of credibility in litigated cases involving FM claims in the Canadian courts, and the relation between perceived credibility and awards granted. A systematic review was conducted of every trial-by-judge litigated FM claim in Canada (N=194 cases) up to 2003. The cases were examined in relation to credibility factors. The role and responsibility of the plaintiff was central in claims involving issues of misrepresentation, fraud, non-disclosure, failure to mitigate, and contributory negligence. The presence of these issues suggested a possible decrease or loss in the claim as a result of the plaintiff's conduct. In regards to the actions of defendants, the presence of investigative and surveillance information alone did not affect the awards granted. However, the credibility of that information had a large effect on the amount of award granted. Plaintiff credibility played a similar role, indicating that plaintiffs perceived as more credible were typically granted greater awards. An examination of medical expert credibility revealed that judges appear to perceive experts as more credible overall than plaintiffs, regardless of the expert's role in the case.

    2015-12-01

    Full Text Available The debate on the role of judiciary in a society and the foundations of the democratic legitimacy of its power has recently acquired a singular relevance. This article aims to bring clarity to the discussion, showing how legal theories have followed a pendulum, swinging between those who think the judicial role and hermeneutical task as an intellectual activity -an act of knowledge-and those who see it as a creative activity-an act of will. Reflecting on the role of judges today raises questions about false dichotomies and encourages to collectively build a new legal and political common sense abandoning traditional legal paradigms.

  15. Voice Patterns in Adult English Speakers with Autism Spectrum Disorder

    DEFF Research Database (Denmark)

    Fusaroli, Riccardo; Lambrechts, Anna; Yarrow, Kielan

    Individuals with Autism Spectrum Disorder (ASD) often display atypical modulation of speech described as awkward, monotone, or sing-songy (Shriberg et al., 2001). These patterns are a robust signal of social communication deficit (Paul et al., 2005) and contribute to reaching a diagnosis of ASD...... autistic from non-autistic speakers in both adult and children Danish speakers with ASD. Objectives: Our first aim was to replicate the results obtained by Fusaroli et al.

    Full Text Available In this paper we describe speaker and command recognition related experiments, through quantile vectors and Gaussian Mixture Modelling (GMM. Over the past several years GMM and MFCC have become two of the dominant approaches for modelling speaker and speech recognition applications. However, memory and computational costs are important drawbacks, because autonomous systems suffer processing and power consumption constraints; thus, having a good trade-off between accuracy and computational requirements is mandatory. We decided to explore another approach (quantile vectors in several tasks and a comparison with MFCC was made. Quantile acoustic vectors are proposed for speaker verification and command recognition tasks and the results showed very good recognition efficiency. This method offered a good trade-off between computation times, characteristics vector complexity and overall achieved efficiency.

    Mayer, Connor; Gick, Bryan

    2012-01-01

    This study looks at how the conflicting goals of chewing and speech production are reconciled by examining the acoustic and articulatory output of talking while chewing. We consider chewing to be a type of perturbation with regard to speech production, but with some important differences. Ultrasound and acoustic measurements were made while participants chewed gum and produced various utterances containing the sounds /s/, /ʃ/, and /r/. Results show a great deal of individual variation in articulation and acoustics between speakers, but consistent productions and maintenance of relative acoustic distances within speakers. Although chewing interfered with speech production, and this interference manifested itself in a variety of ways across speakers, the objectives of speech production were indirectly achieved within the constraints and variability introduced by individual chewing strategies.

    GU Xiaojiang; ZHAO Heming; Lu Gang

    2012-01-01

    In order to increase short time whispered speaker recognition rate in variable chan- nel conditions, the hybrid compensation in model and feature domains was proposed. This method is based on joint factor analysis in training model stage. It extracts speaker factor and eliminates channel factor by estimating training speech speaker and channel spaces. Then in the test stage, the test speech channel factor is projected into feature space to engage in feature compensation, so it can remove channel information both in model and feature domains in order to improve recognition rate. The experiment result shows that the hybrid compensation can obtain the similar recognition rate in the three different training channel conditions and this method is more effective than joint factor analysis in the test of short whispered speech.

    1999-06-01

    The present study was designed to investigate a possible relationship between "recursive anxiety" and paradoxical intention. Groups of subjects were chosen from among individuals with public speaking concerns. and for whom fear of fear or recursive anxiety clearly represented an important element, or was completely absent from the clinical profile. These subjects were offered a standard in vivo treatment program for public speaking phobia with inclusion or exclusion of paradoxical intention. A 2 x 2 factorial design was employed. Those whose public speaking anxiety was complicated by recursive anxiety experienced greater improvement when paradoxical intention was included in the treatment program than when it was not employed. In contrast, individuals reporting simple public speaking phobia demonstrated greater success with a treatment program in which paradoxical intention was absent. Wegner's hypothesis of "ironic" cognitive processing was used to explain the proposed relationship between paradoxical intention and fear of fear.

  3. English speakers attend more strongly than Spanish speakers to manner of motion when classifying novel objects and events.

    2010-11-01

    Three experiments provide evidence that the conceptualization of moving objects and events is influenced by one's native language, consistent with linguistic relativity theory. Monolingual English speakers and bilingual Spanish/English speakers tested in an English-speaking context performed better than monolingual Spanish speakers and bilingual Spanish/English speakers tested in a Spanish-speaking context at sorting novel, animated objects and events into categories on the basis of manner of motion, an attribute that is prominently marked in English but not in Spanish. In contrast, English and Spanish speakers performed similarly at classifying on the basis of path, an attribute that is prominently marked in both languages. Similar results were obtained regardless of whether categories were labeled by novel words or numbered, suggesting that an English-speaking tendency to focus on manner of motion is a general phenomenon and not limited to word learning. Effects of age of acquisition of English were also observed on the performance of bilinguals, with early bilinguals performing similarly in the 2 language contexts and later bilinguals showing greater contextual variation.

    徐向华; 朱杰

    2004-01-01

    A speaker adaptation method that combines transformation matrix linear interpolation with maximum a posteriori (MAP) was proposed. Firstly this method can keep the asymptotical characteristic of MAP. Secondly, as the method uses linear interpolation with several speaker-dependent (SD) transformation matrixes, it can fully use the prior knowledge and keep fast adaptation. The experimental results show that the combined method achieves an 8.24% word error rate reduction with only one adaptation utterance, and keeps asymptotic to the performance of SD model for large amounts of adaptation data.

  7. Inferring word meanings by assuming that speakers are informative.

    Frank, Michael C; Goodman, Noah D

    2014-12-01

    Language comprehension is more than a process of decoding the literal meaning of a speaker's utterance. Instead, by making the assumption that speakers choose their words to be informative in context, listeners routinely make pragmatic inferences that go beyond the linguistic data. If language learners make these same assumptions, they should be able to infer word meanings in otherwise ambiguous situations. We use probabilistic tools to formalize these kinds of informativeness inferences-extending a model of pragmatic language comprehension to the acquisition setting-and present four experiments whose data suggest that preschool children can use informativeness to infer word meanings and that adult judgments track quantitatively with informativeness.

    2010-06-01

    To analyze the opinion of judges and prosecutors concerning Brazilian abortion law and situations in which the abortion should be allowed. A cross-sectional study was performed with 1,493 judges and 2,614 prosecutors in Brazil between 2005 and 2006. Participants completed a structured questionnaire approaching sociodemographic characteristics, opinions about abortion law, and circumstances in which abortion is considered lawful. Bivariate and multivariate analyses of data were carried out through Poisson regression. The majority of participants (78%) found that the circumstances in which abortion is considered lawful should be broadened, or even that abortion should not be criminalized. The highest rates of pro-abortion opinions resulted from: risk to the life of the mother (84%), anencephaly (83%), severe congenital malformation of fetus (82%), and pregnancy resulting from rape (82%). Variables related to religion were strongly associated to the opinion of participants. There is a trend in considering the need of changing the current abortion law, in the sense of widening the circumstances in which abortion is considered lawful, or even toward decriminalizing abortion, regardless of the circumstances in which it takes place.

  9. Judges as Fiscal Activists: Can Constitutional Review Shape Public Finance?

    Directory of Open Access Journals (Sweden)

    Kantorowicz Jarosław

    2014-07-01

    Full Text Available The judicialization of politics, or alternatively, politization of the judiciary has been much discussed over the last twenty years. Despite this, the way judges influence fiscal policy outcomes remains, to a large extent, unexplored. This paper attempts, at least partially, to fill this research gap. A judicial (constitutional review constitutes the central element of the current analysis since it is considered as a key institutional device through which Constitutional (Supreme Courts intervene in politics, including public finance. Specifically, this paper seeks to investigate empirically whether there is any systematic pattern according to which judges executing judicial review shape fiscal outcomes. The conceptual framework is based on the strategic interaction model and the assumption that the Constitutional Courts reflect public opinion (i.e. the Court as a majoritarian institution. Some preliminary results for a panel of 24 EU countries in the period 1995–2005 suggest that a strong judicial review correlates with a smaller size of government, measured as government income to GDP.

    1983-05-01

    Two listener groups, one experienced and the other inexperienced in listening to deaf speakers, were asked to recognize speech sounds in word contexts presented in two modes: auditory only and auditory-visual. In contrast to previous studies, the experienced and inexperienced listener groups performed similarly. The one exception occurred for speech sounds in the final position presented auditory visually where the experienced listeners' performance surpassed that of inexperienced listeners. For both groups, performance in correct phoneme identification was better in the auditory-visual mode of presentation. Furthermore, and interaction between the position-in-word and the mode of stimulus presentation was present in both groups. In the auditory-only task, listeners correctly identified more target phonemes when they were initial rather than final position in a word. With supplemental visual information, listener performance increased our phonemes in both positions within a word, although the increase was greater for final position phonemes.

    2011-01-01

    This paper presents the preliminary works to put online a French oral corpus and its transcription. This corpus is the Socio-Linguistic Survey in Orleans, realized in 1968. First, we numerized the corpus, then we handwritten transcribed it with the Transcriber software adding different tags about speakers, time, noise, etc. Each document (audio file and XML file of the transcription) was described by a set of metadata stored in an XML format to allow an easy consultation. Second, we added different levels of annotations, recognition of named entities and annotation of personal information about speakers. This two annotation tasks used the CasSys system of transducer cascades. We used and modified a first cascade to recognize named entities. Then we built a second cascade to annote the designating entities, i.e. information about the speaker. These second cascade parsed the named entity annotated corpus. The objective is to locate information about the speaker and, also, what kind of information can designate ...

    2003-04-01

    This study aimed at looking at perception of English palatal codas by Korean speakers of English to determine if perception problems are the source of production problems. In particular, first, this study looked at the possible first language effect on the perception of English palatal codas. Second, a possible perceptual source of vowel epenthesis after English palatal codas was investigated. In addition, individual factors, such as length of residence, TOEFL score, gender and academic status, were compared to determine if those affected the varying degree of the perception accuracy. Eleven adult Korean speakers of English as well as three native speakers of English participated in the study. Three sets of a perception test including identification of minimally different English pseudo- or real words were carried out. The results showed that, first, the Korean speakers perceived the English codas significantly worse than the Americans. Second, the study supported the idea that Koreans perceived an extra /i/ after the final affricates due to final release. Finally, none of the individual factors explained the varying degree of the perceptional accuracy. In particular, TOEFL scores and the perception test scores did not have any statistically significant association.

  20. Articulatory settings of French-English bilingual speakers

    Science.gov (United States)

    Wilson, Ian

    2005-04-01

    The idea of a language-specific articulatory setting (AS), an underlying posture of the articulators during speech, has existed for centuries [Laver, Historiogr. Ling. 5 (1978)], but until recently it had eluded direct measurement. In an analysis of x-ray movies of French and English monolingual speakers, Gick et al. [Phonetica (in press)] link AS to inter-speech posture, allowing measurement of AS without interference from segmental targets during speech, and they give quantitative evidence showing AS to be language-specific. In the present study, ultrasound and Optotrak are used to investigate whether bilingual English-French speakers have two ASs, and whether this varies depending on the mode (monolingual or bilingual) these speakers are in. Specifically, for inter-speech posture of the lips, lip aperture and protrusion are measured using Optotrak. For inter-speech posture of the tongue, tongue root retraction, tongue body and tongue tip height are measured using optically-corrected ultrasound. Segmental context is balanced across the two languages ensuring that the sets of sounds before and after an inter-speech posture are consistent across languages. By testing bilingual speakers, vocal tract morphology across languages is controlled for. Results have implications for L2 acquisition, specifically the teaching and acquisition of pronunciation.

  1. Bilingual and Monolingual Children Prefer Native-Accented Speakers

    Directory of Open Access Journals (Sweden)

    Andre L. eSouza

    2013-12-01

    Full Text Available Adults and young children prefer to affiliate with some individuals rather than others. Studies have shown that monolingual children show in-group biases for individuals who speak their native language without a foreign accent (Kinzler, Dupoux, & Spelke, 2007. Some studies have suggested that bilingual children are less influenced than monolinguals by language variety when attributing personality traits to different speakers (Anisfeld & Lambert, 1964, which could indicate that bilinguals have fewer in-group biases and perhaps greater social flexibility. However, no previous studies have compared monolingual and bilingual children’s reactions to speakers with unfamiliar foreign accents. In the present study, we investigated the social preferences of 5-year-old English and French monolinguals and English-French bilinguals. Contrary to our predictions, both monolingual and bilingual preschoolers preferred to be friends with native-accented speakers over speakers who spoke their dominant language with an unfamiliar foreign accent. This result suggests that both monolingual and bilingual children have strong preferences for in-group members who use a familiar language variety, and that bilingualism does not lead to generalized social flexibility.

    This investigation assessed awareness of the oral cavity of nonnative speakers acquiring English. University students (60 men, 60 women) were placed into three equal-size groups. The Less Experienced group lived in the USA less than 6 mo. (M = 3.3 mo., SD = 2.4). The More Experienced group lived in the United States 3 or more years (M = 5.0 yr., SD = 1.9). Native English speakers were the control group. Participants were recruited from undergraduate general education classes and passed a speech screening in English including accurate production of the seven English syllables tested, namely, suh, luh, tuh, kuh, ruh, shuh, and thuh. Participants answered four multiple-choice questions about lingual contact for each of the syllables imitated. Total test mean scores were significantly higher for the More Experienced group. Native speakers performed the task best. Findings support the effects of amount of time speaking the language. Training methods employed to teach English and slight dialectal variations may account for the significant differences seen in the two groups of nonnative speakers. Further study is warranted.

    The purpose of the study was to compare the speech fluency of Brazilian Portuguese speakers with that of European Portuguese speakers. The study participants were 76 individuals of any ethnicity or skin color aged 18-29 years. Of the participants, 38 lived in Brazil and 38 in Portugal. Speech samples from all participants were obtained and analyzed according to the variables of typology and frequency of speech disruptions and speech rate. Descriptive and inferential statistical analyses were performed to assess the association between the fluency profile and linguistic variant variables. We found that the speech rate of European Portuguese speakers was higher than the speech rate of Brazilian Portuguese speakers in words per minute (p=0.004). The qualitative distribution of the typology of common dysfluencies (pspeakers is not available, speech therapists in Portugal can use the same speech fluency assessment as has been used in Brazil to establish a diagnosis of stuttering, especially in regard to typical and stuttering dysfluencies, with care taken when evaluating the speech rate.

  6. Evaluating acoustic speaker normalization algorithms: evidence from longitudinal child data.

    Speaker vowel formant normalization, a technique that controls for variation introduced by physical differences between speakers, is necessary in variationist studies to compare speakers of different ages, genders, and physiological makeup in order to understand non-physiological variation patterns within populations. Many algorithms have been established to reduce variation introduced into vocalic data from physiological sources. The lack of real-time studies tracking the effectiveness of these normalization algorithms from childhood through adolescence inhibits exploration of child participation in vowel shifts. This analysis compares normalization techniques applied to data collected from ten African American children across five time points. Linear regressions compare the reduction in variation attributable to age and gender for each speaker for the vowels BEET, BAT, BOT, BUT, and BOAR. A normalization technique is successful if it maintains variation attributable to a reference sociolinguistic variable, while reducing variation attributable to age. Results indicate that normalization techniques which rely on both a measure of central tendency and range of the vowel space perform best at reducing variation attributable to age, although some variation attributable to age persists after normalization for some sections of the vowel space.

    Target speaker identification is essential for speech enhancement algorithms in assistive devices aimed toward helping the hearing impaired. Several recent studies have reported that target speaker identification is possible through electroencephalography (EEG) recordings. If the EEG system could be reduced to acceptable size while retaining the signal quality, hearing aids could benefit from the integration with concealed EEG. To compare the performance of a multichannel around-the-ear EEG system with high-density cap EEG recordings an envelope tracking algorithm was applied in a competitive speaker paradigm. The data from 20 normal hearing listeners were concurrently collected from the traditional state-of-the-art laboratory wired EEG system and a wireless mobile EEG system with two bilaterally-placed around-the-ear electrode arrays (cEEGrids). The results show that the cEEGrid ear-EEG technology captured neural signals that allowed the identification of the attended speaker above chance-level, with 69.3% accuracy, while cap-EEG signals resulted in the accuracy of 84.8%. Further analyses investigated the influence of ear-EEG signal quality and revealed that the envelope tracking procedure was unaffected by variability in channel impedances. We conclude that the quality of concealed ear-EEG recordings as acquired with the cEEGrid array has potential to be used in the brain-computer interface steering of hearing aids. PMID:27512364
