Children who use cochlear implants acquire more intelligible speech than children with profound hearing loss who use hearing aids. Nevertheless, children with cochlear implants show delays in speech relative to typically hearing children. To date, analyses of speech production in children with cochlear implants have primarily used transcription; however, acoustic analyses are able to characterize speech at a much finer level. The present study describes the productions of “s” and “sh” in children with cochlear implants using both transcription and spectral analysis. These sounds were elicited in word-initial position in familiar words using an auditory word repetition task. It was hypothesized that children with cochlear implants would show greater variability in their productions and less distinction between “s” and “sh” than children with typical hearing. Preliminary results suggest that the productions of children with cochlear implants show more acoustic variability, as well as lower levels of transcription accuracy relative to typically developing peers.
