This 1research examines the relationship between an anticipatory labial gesture and the perception of an upcoming rounded vowel. More specifically, the contribution of anticipatory coarticulation to the perception of the rounded vowel is examined in both the motoric and acoustic levels. The robustness of the temporal extent of the perceptual effect is also evaluated under increased speaking rate. The paradigm consists in generating speech samples by a representative French speaker, then segments are "gated-out" and listeners are asked to judge what the "gated-out" segments were. The issues of acoustic and visual perception of anticipatory vocalic gestures are finally discussed, in trying to provide a general understanding of anticipatory phenomena in speech.
