    COSMO, a Bayesian model of perceptuo-motor interactions in speech communication

    I will present COSMO (Communicating Objects using Sensory-Motor Operations), a
    computational model enabling to analyze the functional role of sensory-motor interactions
    in speech perception and in speech production. I will present three properties of COSMO
    in speech perception, respectively called redundancy, complementarity (with the
    “auditory-narrowband versus motor-wideband” framework) and “specificity” (according to
    which auditory cues would be more efficient for vowel decoding and motor cues more
    efficient for plosive articulation decoding). I will sketch a possible neuroanatomical
    architecture for COSMO, and capitalize on properties of the auditory vs. motor decoders
    to address various neurocognitive studies of the literature. I will conclude on the
    interest of combining a complementary exogenous decoding system, optimally fitted on the
    environment stimuli, with an endogenous decoding system, equipped with generative
