Audiovisual speech processing by Eric Vatikiotis-Bateson( )

18 editions published between 2005 and 2015 in English and held by 921 WorldCat member libraries worldwide

"When we speak, we configure the vocal tract which shapes the visible motions of the face and the patterning of the audible speech acoustics. Similarly, we use these visible and audible behaviors to perceive speech. This book showcases a broad range of research investigating how these two types of signals are used in spoken communication, how they interact, and how they can be used to enhance the realistic synthesis and recognition of audible and visible speech. The volume begins by addressing two important questions about human audiovisual performance: how auditory and visual signals combine to access the mental lexicon and where in the brain this and related processes take place. It then turns to the production and perception of multimodal speech and how structures are coordinated within and across the two modalities. Finally, the book presents overviews and recent developments in machine-based speech recognition and synthesis of AV speech"_Contracub

Origins of human language : continuities and discontinuities with nonhuman primates by Pascal Perrier( )

16 editions published between 2017 and 2019 in English and Undetermined and held by 234 WorldCat member libraries worldwide

This book proposes a detailed picture of the continuities and ruptures between communication in primates and language in humans. It explores a diversity of perspectives on the origins of language, including a fine description of vocal communication in animals, mainly in monkeys and apes, but also in birds, the study of vocal tract anatomy and cortical control of the vocal productions in monkeys and apes, the description of combinatory structures and their social and communicative value, and the exploration of the cognitive environment in which language may have emerged from nonhuman primate vocal or gestural communication
Individual differences in speech production and perception by Pascal Perrier( )

13 editions published in 2015 in English and Undetermined and held by 222 WorldCat member libraries worldwide

Inter-individual variation in speech is a topic of increasing interest both in human sciences and speech technology. It can yield important insights into biological, cognitive, communicative, and social aspects of language. Written by specialists in psycholinguistics, phonetics, speech development, speech perception and speech technology, this volume presents experimental and modeling studies that provide the reader with a deep understanding of interspeaker variability and its role in speech processing, speech development, and interspeaker interactions. It discusses how theoretical models take into account individual behavior, explains why interspeaker variability enriches speech communication, and summarizes the limitations of the use of speaker information in forensics

Speech planning and dynamics by Melanie Weirich( Book )

4 editions published in 2012 in English and held by 19 WorldCat member libraries worldwide

What do we do when we are about to utter speech? On which linguistic units do we rely? How do these units evolve from childhood to adulthood, or across time for a given language? How do we assemble these units under the influences of syntactic, phonological and prosodic rules? Do we plan the whole sequence at once? Do we plan the movements of the tongue, jaw, and lips underlying speech in the same way that we plan other movements? What tools have scientists developed to investigate these questions using observation of articulatory and acoustic signals? This book addresses these issues in eight
The use of sensory feedback in the adaptation of perturbed /s by Jana Brunner( )

1 edition published in 2008 in English and held by 14 WorldCat member libraries worldwide

The study investigates the contribution of tactile and auditory feedback in the adaptation of /s/ towards a palatal prosthesis. Five speakers were recorded via electromagnetic articulography, at first without the prosthesis, then with the prosthesis and auditory feedback masked, and finally with the prosthesis and auditory feedback available. Tongue position, jaw position and acoustic centre of gravity of productions of the sound were measured. The results show that the initial adaptation attempts without auditory feedback are dependent on the prosthesis type and directed towards reaching the original tongue palate contact pattern. Speakers with a prosthesis which retracted the alveolar ridge retracted the tongue. Speakers with a prosthesis which did not change the place of the alveolar ridge did not retract the tongue. All speakers lowered the jaw. In a second adaptation step with auditory feedback available speakers reorganised tongue and jaw movements in order to produce more subtle acoustic characteristics of the sound such as the high amplitude noise which is typical for sibilants

Influence de la forme du palais sur la variabilité articulatoire( )

1 edition published in 2008 in French and held by 12 WorldCat member libraries worldwide

As has been noted previously, speakers with coronally low "flat" palates exhibit less articulatory variability than speakers with coronally high "domeshaped" palates. This phenomenon is investigated by means of a tongue model and an EPG experiment. The results show that acoustic variability depends on the shape of the vocal tract. The same articulatory variability leads to more acoustic variability if the palate is flat than if it is domeshaped. Furthermore, speakers with domeshaped palates show more articulatory variability than speakers with flat palates. The results are explained by different control strategies by the speakers. Speakers with flat palates reduce their articulatory variability in order to keep their acoustic variability low

Speech production and perception: experimental analyses and models( Book )

5 editions published in 2005 in English and held by 5 WorldCat member libraries worldwide

This special issue of the ZAS Papers in Linguistics contains a collection of papers of the French-German Thematic Summerschool on "Cognitive and physical models of speech production, and speech perception and of their interaction". Organized by Susanne Fuchs (ZAS Berlin), Jonathan Harrington (IPdS Kiel), Pascal Perrier (ICP Grenoble) and Bernd Pompino-Marschall (HUB and ZAS Berlin) and funded by the German-French University in Saarbrücken this summerschool was held from September 19th till 24th 2004 at the coast of the Baltic Sea at the Heimvolkshochschule Lubmin (Germany) with 45 participants from Germany, France, Great Britain, Italy and Canada. The scientific program of this summerschool that is reprinted at the end of this volume included 11 key-note presentations by invited speakers, 21 oral presentations and a poster session (8 presentations). The names and addresses of all participants are also given in the back matter of this volume. All participants was offered the opportunity to publish an extended version of their presentation in the ZAS Papers in Linguistics. All submitted papers underwent a review and an editing procedure by external experts and the organizers of the summerschool. As it is the case in a summerschool, papers present either works in progress, or works at a more advanced stage, or tutorials. They are ordered alphabetically by their first author's name, fortunately resulting in the fact that this special issue starts out with the paper that won the award as best pre-doctoral presentation, i.e. Sophie Dupont, Jérôme Aubin and Lucie Ménard with "A study of the McGurk effect in 4 and 5-year-old French Canadian children"

Activations musculaires et mouvements linguaux : modélisation en parole naturelle et pathologique by Stéphanie Buchaillard( )

2 editions published in 2007 in French and held by 4 WorldCat member libraries worldwide

The purpose of the work presented in this manuscript is the development, in the long run, of some interactive software for tongue surgery, based on a three-dimensional biomechanical model of the tongue, allowing the evaluation of the consequences of some surgery on tongue mobility and supporting the planning and the per-operational guidance of the surgical gesture. The studies led to date aim at studying the feasibility of such a tool. The first part of this thesis is devoted to a thorough description of the model used. After the presentation of the vocal tract anatomy and of the clinical context, the model geometry is described with precision (internal structure of the tongue model and representation of the bony and soft structures of the vocal tract). The assumptions carried out for biomechanical modelling are introduced as well as the motor control scheme based on the lambda model of the equilibrium-point hypothesis. The extraction of the vocal tract area function is then presented with the model of speech synthesis. The second part is centred on the results obtained for natural and pathological speech. Our simulations showed the ability of our model to generate the oral vowels of French, with acoustic characteristics close to the values generally observed and satisfactory tongue shapes. Similar simulations are also presented for two cases of tongue surgery: a hemiglossectomy and a widened mouth floor resection
Compensation acoustique et réorganisation articulo-motrice en parole perturbée by Jana Brunner( Book )

2 editions published in 2008 in English and held by 3 WorldCat member libraries worldwide

The present study describes the results of a 2 week perturbation experiment where speaker's vocal tract shape was modified due to the presence of an artificial palate. The aim of the work is to investigate whether speakers adapt towards acoustic or articulatory targets. Speakers were recorded regularly over the adaptation time via electromagnetic articulography and acoustics. Immediately after perturbation onset speaker's auditory feedback was masked with white noise in order to investigate speakers' compensatory behavior when auditory feedback was absent. The results of acoustic measurements show that in vowel production speakers compensate very soon. The compensation in fricatives takes longer and is in some cases not completed within the two weeks. Within a session and for each speaker the sounds can be distinguished solely by acoustic parameters. The differences between the session when no auditory feedback was available and the session when auditory feedback was available was greater for vowels with les palatal contact than for vowel with much palatal contact. In consonant production auditory feedback is primarily used in order to adapt sibilant productions. In general, adaptation tries to keep or enlarge the articulatory and acoustic space between the sounds. Over sessions speakers show motor equivalent strategies (lip protrusion vs. tongue back raising) in the production of /u/. Measurements of tangential jerk suggest that after perturbation onset there is an increase in articulatory effort which is followed by a decrease towards the end of the adaptation time. The compensatory abilities of speakers when no auditory feedback is available suggest that speakers dispose of an articulatory representation. The fact that motor equivalent strategies are used by the speakers, however, supports acoustic representations of speech. It is therefore concluded that articulatory representations belong to the speech production tasks. However since they are modified as soon as the acoustic output is not the desired one any more, they rather function in the domain of movement organization and the acoustic representations dominate
La coarticulation en français et en chinois : étude expérimentale et modélisation by Liang Ma( Book )

2 editions published in 2008 in French and held by 3 WorldCat member libraries worldwide

Comme d'autres mouvements humains, les gestes de la parole sont vraisemblablement planifiés selon des stratégies optimales. Cependant, il est probable que la planification de ces gestes soit aussi contrainte par des critères de nature linguistique. De telles contraintes pourraient porter notamment sur la structure phonologique et la longueur des séquences prises en compte dans la planification. le but de cette thèse a été d'approfondir cette hypothèse à partir de l'analyse de données expérimentales et de simulations avec un modèle. Pour cela, la coarticulation anticipante a été étudiée expérimentalement dans des séquences Voyelle1-Consonne-Voyelle2 (V1CV2) pour deux langues différentes, le français et le chinois, à partir de données articulatoires. Les résultats de nos analyses montrent que les locuteurs français et chinois ont adopté des stratégies de planification différentes : en français l'anticipation s'étend au delà des frontières de la syllabe CV, alors qu'en chinois ce n'est pas le cas. Pour valider cette interprétation sur le rôle de la syllabe, un modèle de contrôle moteur a été élaboré exploitant une stratégie de planification qui minimise un critère combinant effort articulatoire et contraintes perceptives, et il a été testé sur un modèle biomécanique de la langue. Différentes hypothèses sur la structure phonologique de la séquence planifiée ainsi que l'exécution du mouvement ont été testées dans ce cadre. Les simulations ont été comparées aux données. Nos résultats soutiennent l'hypothèse selon laquelle les influences de la syllabe seraient plus fortes en chinois qu'en français
Hallucinations auditives verbales et trouble du langage intérieur dans la schizophrénie : traces physiologiques et bases cérébrales by Lucile Rapin( )

2 editions published in 2011 in French and held by 3 WorldCat member libraries worldwide

Les hallucinations auditives verbales (HAVs) sont des perceptions langagières en l'absence de stimuli externes appropriés. Elles sont un des symptômes les plus invalidants dans la schizophrénie. Parmi les grands types de modèles explicatifs, deux sont particulièrement intéressants : les modèles à origine perceptive, selon lesquels les voix entendues seraient dues à une imagerie mentale et des représentations auditives trop vives et les modèles à origine productive, selon lesquels la parole intérieure est perturbée de telle sorte que les propres pensées verbales du patient sont attribuées à un agent externe. Pour tester le versant moteur des modèles productifs, une expérience de recueil de traces oro-faciales lors des HAVs à l'aide de l'électromyographie de surface a été conduite auprès de 11 patients schizophrènes. Les résultats montrent une tendance à l'augmentation de l'activité musculaire de l'orbiculaire inférieur lors des HAVs par rapport à une condition de repos. Pour tester le versant cérébral des modèles, une expérience en IRMf de génération de pensée verbale et de perception auditive a été menée auprès de 19 sujets schizophrènes et 24 sujets contrôles et a montré une hyper-activation d'un réseau impliquant le cortex temporal et le cortex cingulaire antérieur. La caractérisation phénoménologique des HAVs vécues par les patients a montré que les HAVs diffèrent de la pensée intérieure typique en ce que les voix entendues peuvent être nombreuses et ne sont pas celle du patient lui-même. Ainsi aucun des deux types de modèles considérés isolément n'est satisfaisant pour expliquer les HAVs. Un modèle intégratif multidimensionnel permettrait de mieux rendre compte de la complexité des HAVs. Il existerait, chez les patients schizophrènes une prédisposition perceptive hyper-active couplée à un système de prédiction défaillant. Les deux dysfonctionnements seraient de plus modulés par des facteurs top-down, de stress et un biais cognitif d'externalisation
Modélisation et inversion d'un système complexe de production de signaux acoustiques : application à la voix et aux pathologies by Julien Cisonni( Book )

2 editions published in 2008 in French and held by 3 WorldCat member libraries worldwide

La modélisation physique de la phonation a pour but d'expliquer et reproduire les phénomènes intervenant lors des oscillations des plis vocaux, à l'origine des signaux acoustiques constituant les sons voisés de la parole. Cette thèse propose tout d'abord une étude expérimentale et la modélisation de l'influence de différentes conditions mécaniques, géométriques et acoustiques sur les propriétés des oscillations de répliques déformables de plis vocaux. Un intérêt particulier est ensuite porté sur la modélisation de l'écoulement glottique. L'inversion des modèles unidimensionnels est utilisée pour estimer des quantités généralement considérées comme les paramètres d'entrée/contrôle. Un modèle laminaire 2D basé sur la méthode des éléments finis est mis en oeuvre pour décrire plus finement l'écoulement glottique. Les prédictions des modèles d'écoulement sont confrontées à des mesures in-vitro réalisées sur des répliques rigides de plis vocaux pour différentes conditions
