Gestural overlap, place of articulation and speech rate - an x-ray investigation

Béatrice Vaxelaire, Rudolph Sock, Pascal Perrier

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.
