The phonetic translation of Cued Speech (CS) gestures needs to mix the manual CS information together with the lips, taking into account the desynchronization delay (Attina et al. , Aboutabit et al. ) between these two flows of information. This contribution focuses on the lip flow modeling in the case of French vowels. Previously, classification models have been developed for a professional normal-hearing CS speaker (Aboutabit et al., ). These models are used as a reference. In this study, we process the case of a deaf CS speaker and discuss the possibilities of classification. The best performance (92.8%) is obtained with the adaptation of the deaf data to the reference models.
