This study investigates the relation between para¬meters describing differences between speaker-speci¬fic vocal tract geometries and articulatory distances between the corner vowels based on MRI data of 9 French speakers. Results provide evidence that speaker with a longer pharynx produce larger displacements between low back and high front vowels. Preliminary modeling results are also presented with the aim to study the relation between motor commands, articulation and acoustics
