Modélisation bayésienne de la planification motrice des gestes de parole : Évaluation du rôle des différentes modalités sensorielles

Abstract : An increasing number of experimental results have identified a clear role of auditory and somatosensory information in speech motor control. However, most of the speech production models consider only one of these sensory modalities, or do not provide the possibility to formally evaluate the respective contribution of these modalities. We propose to explore the role of auditory and proprioceptive representations in speech gesture planning, based on a Bayesian model representing the structure of knowledge involved. The model allows to consider three planning mechanisms, based on the auditory or proprioceptive modality or the combination of both. We compare simulations obtained from the two first planning mechanisms. Results indicate differences in the generated articulatory patterns, giving rise however to qualitatively similar patterns of auditory variability.
