This investigation deals with the production of VCV sequences produced by French speakers, with particular focus on larynx position and trajectory. X-ray data are extracted from a database for four speakers, uttering sentences or VCV sequences at two speaking rates: normalconversational and fast. Results obtained from a frame-by-frame analysis of midsagittal profiles reveal: (1) a high positive correlation between the larynx and the hyoid bone in their vertical displacements; 2) a confirmation of previous findings that the position of the larynx is lower for high vowels than for low vowels; (3) anticipatory laryngeal gestures in both /aCu/ and /uCa/ sequences; (4) that these anticipatory gestures are resistant to the behaviour of supraglottal structures, and also to speech rate conditions.
