Interaction entre durée et position dans la perception des fricatives voisées chuchotées

Abstract : Interplay between duration and word position in voicing perception of whispered fricatives This study focuses on the recognition of the voicing-feature in whispered speech. Our previous works in French (Dufour & Meynadier 2019) show a later recognition of the feature [+voiced] probably based on a pre-lexical processing of acoustic information, other than the laryngeal vibration, extracted from the whispered signal and used in lexical access. Via an identification task in categorical perception, this study reveals that duration influences the perception whispered fricatives’ voicing: the longer /ʃ/ is, the more it is perceived [-voiced]; the shorter /ʒ/ is, the more it is identified [+voiced]. This duration effect is modulated by the underlying voicing-feature and the position within the (non-sense) word. The fricative [+voiced] in word-final position shows a perceptual boundary particularly shifted towards durations much longer than the others.
