Speech production in children with cochlear implants: contribution of French Cued Speech

Résumé

A cochlear implant is a widely used device that provides deaf children access to oral speech. However, the auditory information conveyed remains degraded (Colin et al., 2017) and the perception of acoustic features can be altered (Bouton et al., 2015). These limitations may impact oral language development and lead to persistent language disorders (Geers et al., 2015). To compensate for the degraded acoustic input and to enhance speech perception (Leybaert & LaSasso, 2010) some people use Cued French (CF) which supplements the auditory information with a manual cue (Hage & Leybaert, 2006). Each phoneme is systematically associated with a position or configuration of the hand, which facilitates phonological discrimination and encoding. It has been suggested that CF allows deaf children to develop accurate phonological representations (Charlier & Leybaert, 2000). The present study examines whether the improved representations fostered by CF may also contribute to more accurate speech production in CI children.As part of the EULALIES project on speech development in French (Meloni et al., 2017), we have collected data on 84 children with normal hearing (NH), 9 CI children with a low CF decoding level and 8 CI children with a high CF decoding level, aged between 27 and 144 months (Machart et al., 2019). Using a picture-naming task, we analyze the contribution of CF to the speech production abilities of CI children.We find a significant effect of the CF decoding level on phoneme accuracy scores in CI children, independently of chronological age. Our results suggest that exposure to CF improves phoneme accuracy in a picture-naming task in CI children. Analyses are currently extended to further tasks (syllable or pseudoword repetition). We are considering finer descriptions of the errors produced by CI children, with the aim of providing guidelines for targeted speech therapy.
