Abstract : If the studies on Cued Speech CS perception are numerous, those refering to its production by a normalhearing cuer are fewer, and almost non-existent in the case of a deaf cuer. This latter is the topic of this contribution. In an experiment of distant interaction between a deaf participant using CS and a normalhearing participant, we analyze the distance between the vowels from the produced lip shapes. The results show at first that the set of vowels with similar lip shapes so called visemes are the same groups that for a normal-hearing cuer. Secondly, the lip shapes are in coherence with the CS system. Finally, the analysis of the temporal coordination between the CS hand gestures and the lips one, reveals the same scheme as observed at first by Attina 6 with normal-hearing cuers and confirmed by Aboutabit et al.3 in a more complex speech context, i.e. the advance of the CS hand on the lip shapes.
