The purpose of this thesis is to study how the phonemic command, abstract and invariant in nature, is coded in terms of motor control, to generate a physical and variable acoustic signal. A motor control model is exploited, based on the Equilibrium Point hypothesis, proposed by A. Feldman, which suggests that movement results from shifts in variables controlling the system’s mechanical equilibrium. The hypothesis studied here consists in relating discrete motor commands, specifying target equilibrium points, to phonemes. Realistic articulatory and acoustic trajectories were generated with this model for Vowel-Vowel-Vowel sequences, uttered by a French speaker, under several speech conditions. Articulatory trajectories were inferred from the...
