Modélisation de la coarticulation en Langue des Signes Française pour la diffusion automatique d'informations en gare ferroviaire à l'aide d'un signeur virtuel

Abstract : Our research lies in the wake of the efforts to build French Sign Language public announcement systems by virtual signers, using combined prerecorded chunks of utterances. Our study focuses on modelling coarticulation for it to be used in this system. The coarticulation phenomenon is still very little studied in the field of sign language. Using research results in different areas (vocal languages, gesture), we propose a definition of what coarticulation is in Sign Language, and we present a methodology for the analysis of this phenomenon by focusing on hand configuration and gaze direction. We detail the various aspects of corpus creation and annotation, and annotation analysis. Quantitative and qualitative statistics allows us to propose a coarticulation model, based on tensions and relaxations of hand configurations. We propose and implement a methodology for evaluating our model. Finally, we propose prospects for this model in image processing and 3d character animation in French Sign Language.
