Auditory Effects of Anticipatory Rounding in Relation with Vowel Height in French

The present research, based on acoustic data, investigates the relationship between anticipatory labial gestures and perception of upcoming rounded vowels in French Vowel-Consonant-Vowel sequences (V1CV2). V1 is always the high vowel /i/, C corresponds to the fricative /s/, and V2 is one of the following rounded vowels: the high front vowel /y/; the high back vowel /u/; the mid-high front vowel /o/; the mid-high back vowel /o/. As it is known that anticipatory protrusion diminishes as lip aperture increases for rounded vowels, one of the main questions addressed here is: would a reduction in anticipatory protrusion affect the extension of a potential anticipatory auditory effect. The influences of speaker-specific strategies on the auditory behaviour of listeners are also examined.
