What Relationship Between Protrusion Anticipation and Auditory Perception?

This investigation, while confronting data from two speakers, examines the contribution of kinematic and acoustic attributes of protrusion to early perception of a French rounded vowel. The main question addressed here is to determine the relationship between extension of auditory perception and anticipatory expansion of lip protrusion. If extension of auditory perception does increase with anticipatory expansion of lip protrusion, it would be important to determine the nature of the motor-sensory relation, and also the extent to which speaker-specific characteristics may influence the perceptual behaviour of listeners. The robustness of the temporal extent of the perceptual effects is also evaluated under increased speaking rate.
