Miech, Antoine. "Large-scale learning from video and natural language". Electronic Thesis or Diss., Université Paris sciences et lettres, 2020. http://www.theses.fr/2020UPSLE059.
Texto completoThe goal of this thesis is to build and train machine learning models capable of understanding the content of videos. Current video understanding approaches mainly rely on large-scale manually annotated video datasets for training. However, collecting and annotating such dataset is cumbersome, expensive and time-consuming. To address this issue, this thesis focuses on leveraging large amounts of readily-available, but noisy annotations in the form of natural language. In particular, we exploit a diverse corpus of textual metadata such as movie scripts, web video titles and descriptions or automatically transcribed speech obtained from narrated videos. Training video models on such readily-available textual data is challenging as such annotation is often imprecise or wrong. In this thesis, we introduce learning approaches to deal with weak annotation and design specialized training objectives and neural network architectures

Texto completoVideo games are not only a source of entertainment, as they also provide authentic language input for second language learners. Specifically, this study investigates the effect of video games on grammatical mastery of English as a second language (ESL) among a targeted sample of Quebecers. To test the hypothesis that video games impact a higher level of mastery of ESL, an online survey was distributed to 16 volunteer participants who were divided into two specific groups identified as gamers and non-gamers. Participants provided a written text in English of approximately 250 words on any topic which was evaluated for grammar and lexical quality. All participants were UQAC students, and all students were identified as originating from historically high percentage French-speaking environments. Moreover, a small sample of participants was directly observed during the process of gaming to evaluate the specific use and frequency of certain common verb tenses. All submissions were evaluated for the correct use of verb tense and data was gathered based on the number of grammatical and lexical errors. Comparison of these values allows for a qualitative means of analyzing these two groups of participants. In general, it was found that gamers statistically performed better than non-gamers, both grammatically and lexically. They also made fewer mistakes. However, it became apparent during this study that there are additional influences that may contribute to the mastery of ESL.

Texto completoCurrently, the teaching of foreign languages generally aims to teach students to communicate. Referring to the communication to the expression of a vast universe of beliefs and behaviors that are expressed interactively and / or non-interactively, thanks to sensitive and / or intelligible systems. When these beliefs and behaviors, and their forms of expression, are shared by a group of people, we are facing the concept of culture. Thus, foreign students must acquire the essential skills that will enable them to communicate with people of another culture : they will then know, understand and, if possible, acquire all of the information characterizing this culture, that is their verbal and non-verbal activities, their beliefs and communication systems. Nonverbal communication is a vast field within the cultural system of communication, concerning all signs and linguistic signs systems that are used to communicate. The importance of the integration of signs and systems incorporating non-verbal communication in the curricula of FFL (French as a Foreign Language) is reported and included in the European Framework of Reference for Languages : learning, teaching, assessing (Council of Europe, 2001). In the chapter about the use of language, the CEFRL recommends taking into account the skills that students must acquire concerning the actions and gestures used with words (verbal and nonverbal communication), and the situations in which the students will have to implement these skills. Furthermore, it is stated that foreign language learners must be able to identify, recognize and understand the behaviors of paralinguistic, gestural, proxemics and facial expressions of the target language (Council of Europe, 2001: 72-73). The main objective of this study is to select non-verbal signs in the broadest sense for the application to the teaching and learning of the FFL for a Libyan public. In the classroom, these elements can be introduced using video documents representing authentic situations so that learners can observe non-verbal signs and re-use them correctly when intercultural contacts

Texto completoHybrid image born of the contamination of the film image by the video image and then by the digital image, the unhealthy image of the American cinema during the nineties stemmed from the technological changes of the end of the 20th century. Indeed, from an aesthetic point of view, the unhealthy image, usually close to the borders of the ethics of representation, cannot be the result of a moral sentence administered by a looking at a watched. It cannot follow from a judgment of value, difficult to analyze, but must be treated as a medical metaphor, able to highlight the dangerous relationships that may have existed at the end of the 20th century. Also, she sketches, by reinvent the material and language of the traditional American movie, the cinema of the future. Modification of the genetic code of the image, the birth of a representation of the digital body, or the insatiable des ire to mix all sorts of visuals to create out-of-the-ordinary compositions, a lot of factors that push the nineties cinematographic image to reinvent herself. The image was already abject, grotesque, perverse or even pornographic in the American cinema of the Seventies, it will become, hybrid, mutant, and definitely unhealthy in the nineties

Texto completoThis research provides a multimodal analysis of the expression of emotion in two monolingual American children and their parents. The children were filmed in natural interactions in a family setting from the ages of 11 months to 3 years 10 months, and from 1 year 1 month to 4 years.We adopted a broad definition of language in this research which encompasses various semiotic resources – from verbal resources (lexicon and grammatical features), to nonverbal (vocalizations, facial expressions, and gestures). We focus on the children’s acquisition and development of these verbal and nonverbal markers and on how they are used by their parents. Our research shows that children develop specific and distinct communicational patterns, which are greatly influenced by the input to which they are exposed.From a theoretical perspective, our research draws from a constructivist and functionalist approach (Tomasello, 2003), and our data is analyzed in light of language socialization and of studies which have shown that facial expressions and gestures are used as communicational signals in face-to-face dialogue. Our methodology combines quantitative and qualitative methods to investigate each speaker’s verbal and nonverbal behavior when expressing emotions.Having outlined our theoretical and methodological foundation (Part I), we present our results on the expression of three emotions (happiness, sadness, and anger) in children and adults (Part II). Our research suggests that while children’s linguistic development has little impact on the richness of their emotional expression parental input and attitudes both play a crucial role in the acquisition of each modality and in the transmission of communicational patterns

Texto completoThis research examines highly multimodal activities constituting a video project conducted in collaboration with home helpers, in the context of adult language training. The activities under study focus on explaining procedures carried out in various situations, weakly or heavily instrumented (spontaneous group oral, simulation, camera-facing shooting) and participate in the process of appropriation of the foreign language by placing the learner in an expert role. Participant observations in an ethnographic approach, supported by audiovisual recordings of these activities, brought together a corpus that we organized into two main collections. They are based primarily on these data. They deal with the dynamics of multi-sensory, situated actions and interactions (verbal actions, gestures, object manipulations, body placements, movements), as they were developed by the participants. They also discuss the Goffmanian notions of framework, position, commitment and reiteration. This ecological approach to human activity, relatively recent in language science, highlights the multimodality of the resources deployed in those educational situations, and shows their connection with the environment in its social and material dimensions

Texto completoCreation of an interactive video media for teaching and learning oral english hypotheses - digital video and its computer interfaces do not produce negative reactions in student users (the difference is imperceptible). Secondary objective : some users are convinced than they are working on an ordinary vcr and analog video. - the student users (and some teachers) show an interest in digital video and its advantages : access to a choice of individual documents, individual choice of sequencing, in relation to the learners'level of english. Experiments 1) non-correlations - perceived usefulness of the pedagogical tool/use of videocassettes and use of foreign television programs. - use of audio cassettes/perceived usefulness of the session ; comprehension test scores at the beginning and end of the program and the difference between them. In all cases, the khi-2 calculation showed a lack of correlation between the "personal use of media" and "perceived usefulness of the tool" variables. Ii correlations -the higher the diploma obtained, the higher the students' estimate of their level of english. - groups of more than 11 students approve highly of the media tested during the session. - the groups with 11 people or more obtained the best score at all questionnaires of comprehension. - use of foreign television programs/perceived usefulness of the session. Increased usage of videocassettes goes with perceived usefulness of the session, for improved oral comprehension of english. Iii) factorial analysis of correlations - those who frequently use media and obtain an excellent score on the first comprehension questionnaire. - students whose fully appreciative the pedagogical tool used, finds the session interesting for improving his or her english, and obtains an excellent score on the final comprehension questionnaire. This type of student identifies himself as being a "sequential" learner, "shy", subject oriented" and "more visually oriented"

Texto completoThis research focuses on the acquisition and the development of negation in two monolingual French and English children filmed from 10 months to 4 years and 2 months old (66 hours) in natural mother-child dyadic interactions.We use a functionalist and constructivist theoretical approach (Tomasello 2003) but we also bring together French utter-centred approach to language, language socialisation and gesture studies. Our definition of language encompasses all verbal and non-verbal means of expression speakers use to position themselves within interaction. We developed a multimodal coding system relying on the use of several compatible programs to combine qualitative and quantitative analyses. This method offers the opportunity to investigate the expression of negation in verbal and non-verbal modalities in children under 4.After laying the theoretical background (Part 1), we will present our methodology (Part 2). Results show that negation refers to a vast range of pragmatic functions whose expression is fully embodied because it is conveyed through the synchronisation of several modalities of expression (Part 3). Our analysis of the interplay of modalities in the construction of meaning happens to be a great locus to account for the complexity of language. We also observe that negation is a meta-category which can be expressed by a variety of forms.Our research shows that the usage of synchronised modalities in negative contexts can be considered a linguistic and cognitive skill. Moreover, the set of forms for negation develops and specialises after 3 years and helps the child express various communicative intentions linked to negation

Texto completoThis research has been developed in the framework of the project AMIS (Access to Multilingual Information and opinionS). AMIS is an European project which aims to help people to understand the main idea of a video in a foreign language by generating an automatic summary of it. In this thesis, we focus on the automatic recognition and translation of the speech of Arabic and dialectal videos. The statistical approaches proposed in the literature for automatic speech recognition are language independent and they are applicable to modern standard Arabic. However, this language presents some characteristics that we need to take into consideration in order to boost the performance of the speech recognition system. Among these characteristics we can mention the absence of short vowels in the text, which makes their training by the acoustic model difficult. We proposed several approaches to acoustic and/or language modeling in order to better recognize the Arabic speech. In the Arab world, modern standard Arabic is not the mother tongue, that is why daily conversations are carried out with dialect, an Arabic inspired from modern standard Arabic, but not only. We worked on the adaptation of the speech recognition system developed for the modern standard Arabic to the Algerian dialect, which is one of the most difficult variants of the Arabic language to recognize by automatic speech recognition systems. This is mainly due to the borrowed words from other languages, the code-switching and the lack of resources. Our approach to overcome all these problems is to take advantage from oral and textual data of other languages that have an impact on the dialect in order to train the required models for dialect speech recognition. The resulting text from Arabic speech recognition system was then used for machine translation. As a starting point, we conducted a comparative study between the phrase based approach and the neural approach used in machine translation. Then, we adapted these two approaches to translate the code-switched text. Our study focused on the mix of Arabic and English in a parallel corpus extracted from official documents of the United Nations. In order to prevent the error propagation in the pipeline system, we worked on the adaptation of the vocabulary of the automatic speech recognition system and on the proposition of a new model that directly transforms a speech signal in language A into a sequence of words in another language B

Texto completoThe objective of the present study was to explore negotiated interaction involving young children (age 11-12) who carried out communicative tasks supported by Club Penguin Island, a massively multiplayer online role-playing game (MMORPG). Unlike previous studies involving MMORPGs, the present study assessed the use of Club Penguin Island in the context of face-to-face interaction. More specifically, the research questions were three-fold: assess the presence focus-on-form episodes (FFEs) during tasks carried out with Club Penguin Island and identify their characteristics; evaluate the impact of task type on the presence of FFEs; and survey the attitudes of participants. The research project was carried out with 20 Grade 6 intensive English as a second language (ESL) students in the province of Quebec. The participants carried out one information-gap task and two reasoning-gap tasks including one with a writing component. The tasks were carriedout in dyads, and recordings were transcribed and analyzed to identify the presence of FFEs and their characteristics. A statistical analysis was used to assess the impact of task type on the presence of FFEs, and a questionnaire was administered to assess the attitudes of participants following the completion of all tasks. Findings revealed that carrying out tasks with the MMORPG triggered FFEs, that participants were able to successfully negotiate interaction without the help of the instructor, and that most FFEs were focused on the meaning of vocabulary found in the tasks and game. The statistical analysis showed the influence of task type since more FFEs were produced during the information-gap task than one of the reasoning-gap tasks. The attitude questionnaire revealed positive attitudes, which was in line with previous researchon digital games for language learning. Pedagogical implications point to the impact of MMORPGs for language learning and add to the scarce literature on negotiated interaction with young learners.

Texto completoThis research explores the potential of teenage peer spoken interactions in ESL classrooms in France. The focus here is on analysing task-based activities and learners’ performances, in order to improve our understanding of interactional competence. My approach is based on Action Research and a collection of empirical data from language classrooms. Several studies were conducted before setting up a protocol for a longitudinal corpus of video-recorded conversations between 24 dyads of peers. The 48 lower intermediate participants performed two tasks at the beginning and end of the school year. Specific training was offered in order to improve strategic spoken interaction. The 18 hours of verbal and non-verbal outcome was transcribed on CLAN and analysed according to the Conversational Analysis method. On a theoretical level, my approach brings together the European tradition of language didactics based on the CEFR (2001) and the sociocultural theory that takes its roots in Vygotsky’s (1978) work, followed by Lantolf (2000) who deals more specifically with SLA. According to these authors, social interaction not only promotes learning but is also at the core of a development process. This thesis examines the effects of training on communication strategies, the expectable outcomes and assessments of such a competence in an institutional environment

Texto completoThis research studies the behavior of users of a desktop videoconferencing platform VISU (designed to deliver online courses), through the multimodal pedagogical communication of two groups of teachers: trainee tutors and experienced teachers based in different locations who taught French as a Foreign Language to a group of students from UC Berkeley in 2010. A team of researchers and developers worked together with the tutors in this experiment to improve the usability of the platform, which was under construction during the course of the study. In understanding the experience of users while using the tool, due to the performance limitations of the tool under construction, a new method of analysing data was devised in which user behavior was studied through discourse analysis, mimogestuality and the usage of tools including chat and webcam. Specifically, we analysed the usage of different tools (text based tools) as well as the webcam’s effects on user behavior. Then, through a micro analysis of the pedagogical instruction, we identified the role of these different communication tools used by the tutors in conveying the meaning of the task to be carried out. Interviews, questionnaires and perceptions of students and tutors were gathered to inform the analysis of their experiences and their feelings. This research therefore attempts, through the description of the synchronous teaching communication, to better understand the different practices, mainly discursive and mimo-gestural, of tutors and students engaged in the multimodal learning. In addition, a key significance of this study is that it demonstrates the value of considering user experience (UX) in studies involving language learning through technology. At the same time, it also indicates the value of including discourse analysis and mimogestuality in user experience research involving interactive pedagogical tools

Texto completoListening is a complex language competence, dreadful to French students, whose results are low. In reaction to those difficulties, educational authorities encourage teachers to use digital tools whose advantages are not always clear for teachers. Assuming that students should be trained with learning strategies, particularly metacognitive strategies, this study tried to assess how digital video players could develop listening skills. It relates an experiment which took place in a French high school during a four-month period, with four groups working differently, in order to test the use of digital video players and of explicit listening strategies. The use of digital video players played a role in the motivation of students as it enabled them to be engaged in the activity, which did not necessarily mean they were learning more. Guided work on the video players aimed at developing cognitive and metacognitive strategies, and we observed the way students complied with the guidelines they had been given, as well as the changes introduced in the classroom in terms of interactions. The use of digital video players and strategies had an impact on the students' skills in terms of metacognition and perception, but not on the students' listening performance. Those results question the way listeners should be helped and trained when listening to English texts, and more broadly how to deal with the issue of technology-mediated language learning

Texto completoThis thesis proposes to study the use of authentic documents in the teaching/learning of F.L.E. (French as a foreign language) to Chinese students in an intercultural perspective. We first tried to understand the emergence and imposition of an intercultural approach in the didactic of F.L.E. today. We also studied the roles of authentic documents in the teaching of foreign languages in order to develop intercultural communication competence. We then tried to justify our study from an empirical research based firstly on a presentation-analysis of the current situation of the teaching of F.L.E. in China (the university) and secondly on a survey of learners and teachers. Finally, we discussed the impact of authentic materials as teaching tool for an intercultural approach to teaching/learning of French through a teaching experience conducted in a Chinese university for one academic semester

Texto completoAlthough they are widely used, classical vibration measurements have several limitations. Vibration analysis can only identify about 60% of the defects that may occur in mechanical systems. However, the main drawbacks of vibration measurements are the difficult access to the transmission system in order to place the sensor as well as the consequent cost of implementation. This results in sensitivity problems relative to the position of the installation and the difficulty to distinguish the source of vibration because of the diversity of mechanical excitations that exist in the industrial environment.Hence, the Motor Current Signatures Analysis (M.C.S.A.) represents a promising alternative to the vibration analysis and has therefore been the subject of increasing attention in recent years. Indeed, the analysis of electrical signatures has the advantage of being a technically accessible method as well as inexpensive and non-intrusive to the system. Techniques based on currents and voltages only require the motor’s electrical measurements which are often already supervised for the purposes of the control and the protection of the electrical machines. This process was mainly used for the detection of motors faults such as rotor bars breakage and eccentricity faults as well as bearings defects. On the other hand, very little research has been focused on gear faults detection using the current analysis. In addition, three-phase electrical signals are characterized by specific geometric representations related to their waveforms and they can serve as different indicators providing additional information. Among these geometric indicators, the Park and Concordia transforms model the electrical components in a two-dimensional coordinate system and any deviation from the original representation indicates the apparition of a malfunction. Moreover, the differential equations of Frenet-Serret represent the trajectory of the signal in a three-dimensional euclidean space and thus indicate any changes in the state of the system. Although they have been previously used for bearing defects, these indicators have not been applied in the detection of gear defects using the analysis of electrical current signatures. Hence, the innovative idea of combining these indicators with signal processing techniques, as well as classification techniques for gears diagnosis using the three-phase motor’s electrical current signatures analysis is established.Hence, in this work, a new approach is proposed for gear faults diagnosis using the motor currents analysis, based on a set of geometric indicators (Park and Concordia transforms as well as the properties of the Frenet-Serret frame). These indicators are part of a specifically built fault signatures library and which also includes the classical indicators used for a wide range of faults. Thus, a proposed estimation algorithm combines experimental measurements of electrical signals with advanced signal processing methods (Empirical Mode Decomposition, ...). Next, it selects the most relevant indicators within the library based on feature selection algorithms (Sequential Backward Selection and Principal Component Analysis). Finally, this selection is combined with non-supervised classification (K-means) for the distinction between the healthy state and faulty states. It was finally validated with a an additional experimental configuration in different cases with gear faults, bearing faults and combined faults with various load levels

Texto completoTeaching oral communication implies that teachers are aware of different parameters so that students can acquire solid and durable learning skills. In this regard, we can identify amongst other things, the taking into account of the distinctions between oral and written production and the stress induced by having to deliver speeches or by the volatile aspect of this form of communication. Although different methods and tools have been suggested and validated in order to allow students to adequately develop this competency, there remain associated challenges such as the metacognitive aspect of learning. Certainly, the didactic models offer in their structure a place for reflexive activities but how can we adequately accompany students so that these activities allow them to grasp their full potential? Therefore, this study proposes to explore the use of a tool that fosters precise implementation of reflexive activities, the digital learning portfolio, and to describe the contributions regarding the development of the oral production competency of Grade 9 students in the French Language of Instruction class. To attain this general research objective, we relied on a theoretical framework primarily presenting general elements regarding oral teaching and learning and secondly, the use of learning portfolios in high school. Three complementary elements complete this theoretical framework: self-evaluation, emotional commitment and self-regulated learning. To meet the specific research objectives arising from these concepts, a qualifying and interpretative method, exploratory in nature, has been developed that includes 77 Grade 9 students. Since this is a thesis of articles, every specific research objective is a subject of an article. In the first article, we have described the contribution of the digital learning portfolio on self-evaluation of high school students in the competency of oral production. Our results show that reflexive tools associated to the portfolio, especially thanks to video, allow for a better identification of strengths and weaknesses in oral production. In the second article, we have described the contribution of this tool on the emotional commitment of students. In light of obtained results, the learning portfolio offers an added value in terms of stress reduction associated with the development of oral production work. In the last article, we have expanded our description of contributions of tools in the use of strategies to self-regulate in the context of learning through oral production. The analyzed data illustrates that certain self-regulating processes, such as planning strategies and self-recording, benefit from the steps associated in the development of a digital learning portfolio. In conclusion, a synthesis and analysis of all the results regarding the literature and recommendations are proposed in order to offer courses of action and training for the professionals in a school environment, particularly French high school teachers.

Texto completoThe exploration of the information technologies in the classroom, especially in language teaching, has a very positive acceptance but it still needs to be studied in what the identification of dimensions and factors which help the efficiency and pedagogical effectiveness are concerned. The present study is a qualitative investigation as a study case, that has as aim to ascertain the impact provided by the use of video during the teaching of French Foreign Language in order to check students reactions and attitudes during their interaction with this instruments in the classroom and discover the contribution of the video for the teaching and learning process. The pedagogical dynamics of use of video in research was not only used on the classic way, with the preview of audio-visual documents, but it envolved particularly the participants in the creation of videos through the edition with appropriate software of animated and synchronized images with text and voice. We tried to confirm the possibilities offered by the use of the Web 2.0 on a learning context and the different tools at its disposal, with particular attention to the YouTube, Facebook and Xtranormal services. We identified vehicles of data collection, to recognize the subjective importance, on this context, of the success factors of the technologies use, in the classroom, concerning the teaching of a foreign language. After the analysis of the collected datum, it was evident that students acquired a stronger consciousness of the potentialities of the video and Web 2.0 tools use on the teaching and learning process and we do recognize that the usage of these tools allowed a motivation and participation increase, on the subject, as well as in the development of oral and written skills. We experienced that the video is an option as a technologic resource suitable and beneficial in the teaching of a foreign language, as along as it is used on an appropriate way, with the right planning of activities and strategies to be applied, conjugated with other media and educational resources.
L’exploration des technologies de l’information en salle de classe, notamment dans l’enseignement des langues, semble permettre une réception positive mais manque d’étude en ce qui concerne l’identification des dimensions et des facteurs qui lui facilitent l’efficience et l’efficacité pédagogique. La présente étude est une investigation qualitative, sous forme d’étude de cas, qui a pour objectif analyser l’impact suscité par le recours à la vidéo en cours de Français Langue Étrangère, de façon à vérifier quelles sont les attitudes et les réactions des élèves pendant leur intéraction avec ces instruments en salle de classe, bien comme savoir quelle est la contribution des vidéos pour le processus d’enseignement et apprentissage. La dynamique pédagogique de l’utilisation de la vidéo dans notre investigation n’a pas seulement été employé de forme classique, avec la visualisation de documents audiovisuels, mais a particulièrement impliqué les participants dans la création de vidéos à travers l’édition avec software appropriée d’images animées et synchronisées avec texte et voix. Nous avons essayé de démontrer les possibilités liés à l’utilisation de la Web 2.0, en contexte éducatif, et les différents outils à sa disposition, particulièrement en ce qui concerne les services du YouTube, Facebook et Xtranormal. Après avoir analysé les données recueillies, il est devenu évident que les étudiants ont acquis une plus grande sensibilisation sur les potencialités de l’utilisation des vidéos et outils de la Web 2.0 en contexte d’enseignement et apprentissage et nous reconnaissons que l’application de ces outils a permis une augmentation de la motivation et de la participation dans la discipline, bien comme dans le développement de compétences au niveau de l’oralité et de l’écrit. Nous avons constaté que la vidéo se constitue comme option de ressource technologique appropriée et enrichissante dans l’enseignement des langues étrangères, du moment qu’elle soit utilisée correctement, avec une planification adéquate des activités et des stratégies à mettre en oeuvre, et combinée avec d’autres médias et ressources éducatives.

Texto completoThis master's thesis aims at pinpointing the pros and cons of using the dynamic functionnal language Scheme for developing video games. The method used is first based on a theoretical approach. Indeed, the specific requirements for video game programming and a detailed description of relevant Scheme features are presented. Then, a practical approach is taken by presenting two video games developed using the Scheme language: Space Invaders and Lode Runner. Their development resulted in the creation of various domain-specific languages and libraries, such as an objec- oriented system and a coroutine system. Each of these are presented separately in their respective chapter. Finally, the experience achieved in this process is compared to the experience acquired by some video game companies that also used Scheme for the developpement of their titles. The use of Scheme allowed us to perform various high-level abstractions that improved the modularity of the video games developed, without affecting their performance.

Texto completoC’est tombé dans l’oreille d’une Sourde. La sourditude par la bande dessignée est une recherche-création composée d’un essai doctoral et d’une bande dessignée - une bande dessinée bilingue en langue des signes québécoise (LSQ) et en français (BD*) - produite à partir d’extraits de rencontres avec des personnes sourdes et des membres de ma famille entendante réalisées dans le cadre de la thèse. Par une démarche exploratoire, la recherche vise à documenter et à réfléchir à ce que cela fait de vivre comme personne sourde, à la sourditude comme devenir, à l'entendance comme concept pour réfléchir à certains rapports de pouvoirs ainsi qu’aux enjeux communicationnels, technologiques et médiatiques soulevés par les perspectives épistémologiques sourdiennes. C’est en partant du postulat que l’oppression est ce qui est éprouvé à travers des pratiques quotidiennes souvent bien intentionnées (Young, 1990) et avec le désir de composer avec l’exigence du multiple (Deleuze et Guattari, 1980) que s’est développée la question générale de la thèse : En la posant comme un devenir complexe, comment l'expérience singulière de la sourditude, son affectivité et son effectivité se conçoivent, s'actualisent et se communiquent-elles? Cette question se pose dans son articulation avec le lieu où elle prend forme, à savoir la réalisation d’un essai doctoral et d’une BD*, dont le processus sert de milieu exploratoire à diverses questions d’ordre philosophique, théorique, épistémologique, éthique, artistique et politique qui, à leur tour, nourrissent la démarche. Utilisant la vidéo comme forme d’écriture apte à rendre compte de la tridimensionnalité des langues des signes et de leurs composantes linguistiques, la BD* est produite sous forme de chapitres vidéo diffusés sur un site Internet. Produite en noir et blanc, elle comporte des vidéos de protagonistes signant la LSQ, éditées avec un effet de dessin animé, des textes en français disposés dans des phylactères et des arrière-plans édités avec un logiciel de graphisme. Écrit sous forme de dissertation, l’essai comporte cinq chapitres. De façon sommaire, l’introduction présente la recherche-création, la question de recherche et les différentes parties de l’essai; le chapitre 1 intitulé « Les possibles de la sourditude » met en jeu quelques éléments afin d’appréhender la sourditude dans sa complexité, problématise et historicise la sourditude en tant que processus, devenir et appartenance, théorise diverses dimensions de l’oppression, interroge l'expérience subjective comme site de savoirs et propose une analyse critique du concept de sourditude; le chapitre 2 intitulé « Parcours de recherche-création » s’articule autour de la démarche de réalisation de la BD*, documente mon approche de la recherche-création, interroge ma posture épistémologique à travers le paradoxe de vouloir contribuer à « faire entendre des voix sourdes », discute des enjeux soulevés par l’écriture vidéographiée, s’intéresse aux enchevêtrements du cinéma et de la sourditude sous divers angles et discerne certains enjeux relatifs à la situation de la BD* aux confins des codes de la littérature, du cinéma et de la BD; le chapitre 3 intitulé « La production de la bande dessignée » s’attarde de façon plus précise aux diverses étapes de réalisation de la BD*, aborde les rencontres réalisées avec cinq Sourd-es et quatre membres de ma famille entendante, documente le processus de production et postproduction de la BD* en soulevant certains enjeux sur le plan de la traduction et du montage, analyse de façon critique l’Internet comme plateforme de diffusion et présente le site Internet www.BDLSQ.net; la conclusion intitulée « Quelques enjeux posés par la sourditude » propose certaines réflexions issues des rencontres, interroge la question des technologies à travers la notion de sourditude et du handicap, amorce une réflexion sur l’agentivité conférée par les media numériques et se termine en soulevant quelques enjeux politiques et éthiques concernant le développement des études sourdes et des perspectives sourdiennes.

It Fell on Deaf Ears. Deafhood by Graphic Signed Novel (C’est tombé dans l’oreille d’une Sourde. La sourditude par la bande dessignée) is a research-creation project consisting of a doctoral essay and a bilingual graphic signed novel in Québec sign language (LSQ) and in French, produced from excerpts of encounters with Deaf people and with members of my hearing family that have been carried out as part of the thesis. Through an exploratory process, the project seeks to document and to reflect upon what it means to live as a Deaf person, about Deafhood as becoming, about hearingness as a concept that can be used to think about certain power relations, as well as about the communicative, technological and media issues that arise from deafian epistemological perspectives. From the assumption that oppression is experienced through often well-intentioned everyday practices (Young, 1990), and from an interest in dealing with the requirement of multiplicity (Deleuze and Guattari, 1980), was developed the broad question of the thesis: while positioning it as a complex becoming, how can the singular experience of Deafhood, its affects and effects, be conceived, actualized and communicated? This question is posed through its articulation with the site where it takes shape, namely the creation of a doctoral essay and a graphic signed novel, the process of which serves as an exploratory site for various philosophical, theoretical, epistemological, ethical, artistic and political questions, which, in turn, feed the process. Using video as a form of writing that is able to account for the three-dimensionality of sign languages and of their linguistic components, the graphic signed novel is produced as video chapters distributed on a website. Produced in black and white, it features videos of protagonists signing in LSQ edited with a cartoon effect, French text inscribed in speech bubbles, and backgrounds that have been edited with graphic design software. The production team and the project are presented in LSQ, ASL, French and English on the website www.BDLSQ.net. Written in the form of a dissertation, the essay includes five chapters. In summary, the introduction presents the research-creation project, the research question and the different parts of the essay. Chapter 1, titled “The Possibilities of Deafhood”, brings together elements that help us understand Deafhood in its complexity, problematizes and historicizes Deafhood as a process, becoming and belonging, theorizes various dimensions of oppression, questions the subjective experience as a site of knowledge, and provides a critical analysis of the concept of Deafhood. Chapter 2, titled “Trajectory of Research-Creation”, revolves around the process of making a bilingual graphic signed novel; documenting my research-creation approach, and questioning my epistemological stance through the paradox of wanting to make “Deaf voices heard”. The chapter further discusses issues raised by videographed writing, is interested in the entanglements of film and Deafhood from various angles, and identifies some questions related to the place of the graphic signed novel in relation to the confines of the codes of literature, film and the graphic novel. Chapter 3, titled “The Creation of the Graphic Signed Novel”, focuses more specifically on the various production stages of the graphic signed novel. It addresses the meetings held with five Deafs and four members of my hearing family, documents the production and postproduction processes of the graphic signed novel while raising some issues related to translation and editing, analyzes, in a critical way, the internet as a distribution platform, and introduces the website www.BDLSQ.net. The conclusion, titled “Some Challenges Posed by Deafhood”, offers some reflections stemming from the meetings, interrogates the question of technologies through the notions of Deafhood and disability, proposes a reflection on agency afforded through digital media, and ends by raising some political and ethical issues related to the development of Deaf studies and perspectives.
