This investigation deals with the production of consonant
sequences in French, with particular focus on overlap of labial,
apical, tongue-dorsum and velar gestures. X-ray and acoustic
data are obtained for two speakers, at two speaking rates,
normal-conversational and fast. Speech rate is varied in order to
explore gestural overlapping possibilities, when places of
articulation differ between plosives. Results show that:
anticipatory coarticulation is not systematically predominant;
anticipatory or perseverative coarticulation may or may not
occur depending on similarity/dissimilarity in place of
articulation between contiguous consonants; vowels are less
resistant than consonants to velar coarticulation; speech rate
facilitates gestural overlap. Findings are explained in terms of
biomechanical and viable linguistic constraints.
