Abstract : This thesis investigates acoustic-to-articu1atory inversion, i.e. recovering articulatory movements from the speech signal. In this work, we present an important evolution of codebooks methods, i.e. methods using acoustic-articulatory tuples precomputed using an acoustic synthesis model. Apart from the inversion method, we present the introduction of two types of constraints: generic phonetic constraints, derived from the analysis by human experts of articulatory invariance for vowels, and visual constraints, i.e. constraints derived automatically from a video signal, in our case a stereo video signal, thus allowing us to perform multimodal inversion.
