In this study, we investigated how CS information interacts with natural speech using Event-Related Potential (ERP) analyses in French-speaking, typically hearing adults (TH) who were either naïve or experienced CS producers. The audiovisual (AV) presentation of lipreading information elicited an amplitude attenuation of the entire N1 and P2 complex in both groups, accompanied by N1 latency facilitation in the group of CS producers. Adding CS gestures to lipread information increased the magnitude of effects observed at the N1 time window, but did not enhance P2 amplitude attenuation. Interestingly, presenting CS gestures without lipreading information yielded distinct response patterns depending on participants’ experience with the system. In the group of CS producers, AV perception of CS gestures facilitated the early stage of speech processing, while in the group of naïve participants, ...

On the basis of behavioral and neuroimaging data, we argue here that manual, not lipread, information plays the primary role in the processing of CS. We also argue that CS combined with a cochlear implant (CI) is a powerful tool. We review the avalable literature showing that CS enhances speech perception in CI children, and it also favors the appropriate development of the three R's (reading, rhyming, and remembering). The chapter concludes with considerations regarding the future of CS systems and the necessity to explicitly train deaf children with CIs to use not only auditory information, but also visual speech information.

L'A. explique en quoi les enfants exposes a cette methode de communication connaissent un developpement du langage oral comparable a celui d'enfants entendants et se basent sur des representations internes de la parole dans leurs activites mentales
