Prosodisk förmåga hos svenska grundskolebarn med cochleaimplantat

Sammanfattning: Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different. The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing. The purpose of the study was also to examine differences between these two groups and to characterize those differences. Eight children with cochlear implants and eight controls matched to age, sex and regional accent were included in the study. The children’s production and perception of prosody was tested. The results show that there are differences in prosodic skills between the children with cochlear implants and their matched controls at word, phrase and discourse levels. The differences were significant in production but not in perception. Observed differences in the speech of the children with cochlear implants included omission of unstressed syllables and function words, difficulties producing contrast of tonal word accents and pro-longed maintenance of phonological processes. The study contributes to the knowledge about prosodic and linguistic skills in Swedish children with cochlear implants.
