Full textThis thesis focused on the relations between biological movements and auditory perception in considering the specific case of graphical movements and the friction sounds they produced. The originality of this work lies in the use of sound synthesis processes that are based on a perceptual paradigm and that can be controlled by gesture models. The present synthesis model made it possible to generate acoustic stimuli which timbre was directly modulated by the velocity variations induced by a graphic gesture in order to exclusively focus on the perceptual influence of this transformational invariant. A first study showed that we can recognize the biological motion kinematics (the 1/3 power law) and discriminate simple geometric shapes simply by listening to the timbre variations of friction sounds that solely evoke velocity variations. A second study revealed the existence of dynamic prototypes characterized by sounds corresponding to the most representative elliptic trajectory, thus revealing that prototypical shapes may emerged from sensorimotor coupling. A final study showed that the kinematics evoked by friction sounds may significantly affect the dynamic and geometric dimension in the visuo-motor coupling. This shed critical light on the relevance of auditory perception in the multisensory integration of continuous motion in a situation never explored. All of these theoretical results enabled the gestural control of sound synthesis models from a gestural description and the creation of sonification tools for gesture learning and rehabilitation of a graphomotor disease, dysgraphia

Full textThis work takes place in the general framework of communication and interaction in virtual reality environment. We are particularly interested in the nonverbal communication between humans and autonomous virtual actor. We position our work in the field of gesture interaction that is as natural as possible. Then, our problematic is to perceive and recognize a gesture or a sequence of gestures in realtime. In this context, we search to implement an effective model of gesture recognition. There are currently difficulties on the analysis of dynamic gestures. All studies from the state of the art described in this thesis refer all on the transcription of gestures into symbols. An effective recognition system should respond to: quick and easy learning stage; real-time recognition; automatic segmentation of the flow of movements; scalability of the database. To our knowledge, no system meet all these characteristics simultaneously. Our proposal is to base our model on gesture signature. This summerize the essence of the gesture. We show that using a compression technique based on PCA and a proper geometric adjustement we can compute a representation containing the information needed to characterize the gesture and faciitate the comparison with the observation of real-time flow. We introduce a new technique for segmenting the real-time flow based on the combination of the signature and an agent model. We applied our work, with success, on laboratory conditions evaluations and then in front of an audience in a play based on a Capoeira script in a theater

Full textRobots become more and more omnipresent in our life and society, and many challenges arise when we try to use them in a social context. This thesis focuses on how to generate an adapted robot’s behavior to human’s profile so as to enhance the human-robot relationship. This research addresses a wide range of complex problems varying from analyzing and understanding human’s emotion and personality to synthesizing a complete synchronized multimodal behavior that combines gestures, speech, and facial expressions. Our methodologies have been examined experimentally with NAO robot from Aldebaran Robotics and ALICE robot from Hanson Robotics. The first part of this thesis focuses on emotion analysis and discusses its evolutionary nature. The fuzzy nature of emotions imposes a big obstacle in front of defining precise membership criteria for each emotion class. Therefore, fuzzy logic looks appropriate for modeling these complex data sets, as it imitates human logic by using a descriptive and imprecise language in order to cope with fuzzy data. The variation of emotion expressivity through cultures and the difficulty of including many emotion categories inside one database, makes the need for an online recognition system of emotion as a critical issue. A new online fuzzy-based emotion recognition system through prosodic cues was developed in order to detect whether the expressed emotion confirms one of the previously learned emotion clusters, or it constitutes a new cluster (not learned before) that requires a new verbal and/or nonverbal action to be synthesized. On the other hand, the second part of this thesis focuses on personality traits, which play a major role in human social interaction. Different researches studied the long term effect of the extraversion-introversion personality trait on human’s generated multimodal behavior. This trait can, therefore, be used to characterize the combined verbal and nonverbal behavior of a human interacting with a robot so as to allow the robot to adapt its generated multimodal behavior to the interacting human’s personality. This behavior adaptation could follow either the similarity attraction principle (i. E. , individuals are more attracted by others who have similar personality traits) or the complementarity attraction principle (i. E. , individuals are more attracted by others whose personalities are complementary to their own personalities) according to the context of interaction. In this thesis, we examine the effects of the multimodality and unimodality of the generated behavior on interaction, in addition to the similarity attraction principle as it considers the effect of the initial interaction between human and robot on the developing relationship (e. G. , friendship), which makes it more appropriate for our interaction context. The detection of human’s personality trait as being introverted or extraverted is based on a psycholinguistic analysis of human’s speech, upon which the characteristics of the generated robot’s speech and gestures are defined. Last but not least, the third part of this thesis focuses on gesture synthesis. The generation of appropriate head-arm metaphoric gestures does not follow a specific linguistic analysis. It is mainly based on the prosodic cues of human’s speech, which correlate firmly with emotion and the dynamic characteristics of metaphoric gestures. The proposed system uses the Coupled Hidden Markov Models (CHMM) that contain two chains for modeling the characteristic curves of the segmented speech and gestures. When a speech-test signal is present to the trained CHMM, a corresponding set of adapted metaphoric gestures will be synthesized. An experimental study (in which the robot adapts the emotional content of its generated multimodal behavior to the context of interaction) is set for examining the emotional content of the generated robot’s metaphoric gestures by human’s feedback di- rectly. Besides, we examine the effects of both the generated facial expressions using the expressive face of ALICE robot, and the synthesized emotional speech using the text to speech toolkit (Mary-TTS) on enhancing the expressivity of the robot, in addition to comparing between the effects of the multimodal interaction and the interaction that employs less affective cues on human. Generally, the research on understanding human’s profile and generating an adapted robot’s behavior opens the door to other topics that need to be addressed in an elaborate way. These topics include, but not limited to: developing a computational cognitive architecture that can simulate the functionalities of the human brain areas that allow understanding and generating speech and physical actions appropriately to the context of interaction, which constitutes a future research scope for this thesis

Full textThe subject of this thesis was the study and conception of a platform for expressive speech synthesis.The LIPS3 Text-to-Speech system — developed in the context of this thesis — includes a linguistic module and a parametric statistical module (built upon HTS and STRAIGHT). The system was based on a new single-speaker corpus, designed, recorded and annotated.The first study analyzed the influence of the precision of the training corpus phonetic labeling on the synthesis quality. It showed that statistical parametric synthesis is robust to labeling and alignment errors. This addresses the issue of variation in phonetic realizations for expressive speech.The second study presents an acoustico-phonetic analysis of the corpus, characterizing the expressive space used by the speaker to instantiate the instructions that described the different expressive conditions. Voice source parameters and articulatory settings were analyzed according to their phonetic classes, which allowed for a fine phonostylistic characterization.The third study focused on intonation and rhythm. Calliphony 2.0 is a real-time chironomic interface that controls the f0 and rhythmic parameters of prosody, using drawing/writing hand gestures with a stylus and a graphic tablet. These hand-controlled modulations are used to enhance the TTS output, producing speech that is more realistic, without degradation as it is directly applied to the vocoder parameters. Intonation and rhythm stylization using this interface brings significant improvement to the prototypicality of expressivity, as well as to the general quality of synthetic speech.These studies show that parametric statistical synthesis, combined with a chironomic interface, offers an efficient solution for expressive speech synthesis, as well as a powerful tool for the study of prosody

Full textThe generation of expressive gestures allows Embodied Conversational Agents (ECA) to articulate the speech intent and content in a human-like fashion. The central theme of the manuscript is to leverage and control the ECAs’ behavioral expressivity by modelling the complex multimodal behavior that humans employ during communication. The driving forces of the Thesis are twofold: (1) to exploit speech prosody, visual prosody and language with the aim of synthesizing expressive and human-like behaviors for ECAs; (2) to control the style of the synthesized gestures such that we can generate them with the style of any speaker. With these motivations in mind, we first propose a semantically aware and speech-driven facial and head gesture synthesis model trained on the TEDx Corpus which we collected. Then we propose ZS-MSTM 1.0, an approach to synthesize stylized upper-body gestures, driven by the content of a source speaker’s speech and corresponding to the style of any target speakers, seen or unseen by our model. It is trained on PATS Corpus which includes multimodal data of speakers having different behavioral style. ZS-MSTM 1.0 is not limited to PATS speakers, and can generate gestures in the style of any newly coming speaker without further training or fine-tuning, rendering our approach zero-shot. Behavioral style is modelled based on multimodal speakers’ data - language, body gestures, and speech - and independent from the speaker’s identity ("ID"). We additionally propose ZS-MSTM 2.0 to generate stylized facial gestures in addition to the upper-body gestures. We train ZS-MSTM 2.0 on PATS Corpus, which we extended to include dialog acts and 2D facial landmarks

Full textNum mercado extremamente competitivo, e que enfrenta grandes constrangimentos económicos em Portugal, a aposta na qualidade de serviço pode ser o factor diferenciador para as empresas. Este estudo analisa a qualidade de serviço prestado pela DePuy Synthes Spine, unidade de negócio pertencente ao grupo de companhias da Johnson & Johnson, através de um questionário criado de acordo com as especificidades do sector. A amostra é composta por 50 clientes da DePuy Synthes Spine (dos quais 18 enfermeiros, 21 médicos e 11 administrativos). Os resultados obtidos mostram que todos os inquiridos estão, em média, muito satisfeitos com os vários items da qualidade de serviço em análise. Verificou-se que enfermeiros, ortopedistas e neurocirurgiões apresentam o mesmo grau de satisfação relativamente a todos os aspectos da qualidade de serviços em análise. Observaram-se diferenças no grau de concordância entre os indivíduos do género masculino e feminino nos items “o consultor DePuy Synthes que o visita tem conhecimentos técnicos para responder às perguntas que lhe faz”, “os instrumentos funcionam devidamente”, “Quando tem um problema com os produtos, o consultor mostra um interesse sincero em solucioná-lo”, “os colaboradores da DePuy Synthes transmitemlhe confiança”. Relativamente ao local de trabalho,os indivíduos que trabalham no hospital público apresentam o mesmo nível de satisfação que os inquiridos que trabalham no hospital privado. Os resultados sugerem também que quanto maior o número de anos de utilização dos produtos, menor o grau de concordância com os items “a postura do consultor que o visita é adequada” e “quando tem um problema com os produtos, o consultor mostra um interesse sincero em solicioná-lo”.
