- Résumé : In a previous study (Troille & Cathiard, 2006) on vowel rounding anticipatory perception through a fricative consonant stream, we demonstrated that auditory information could be, in this VCV frame, ahead of visual information, and even of audiovisual information. We propose here to extend this experiment to 7-11-year-old children and to adults, both with normal and impaired hearing. Results showed that, if normal and impaired hearing subjects, both adults and children, had the same late performance in vision only, impaired hearing practicing French Cued Speech succeeded in the identification task as precociously as normal hearing in the auditory condition. Hence given the best available information, provided it anticipates on vision, be it the audio channel or manual CS coding, subjects take the best advantage of the natural timing of the different sensory informations. So the hand can substitute in time for the spoken sounds.
