- Abstract
- This study investigates the differences in mean F0, intensity, jitter, and shimmer across hearing aid, gender, and vowels. For this study, 18 hearing-impaired children, 18 cochlear implanted children, and 18 normal hearing children as a control group were asked to read seven Korean vowels (/a, Λ, o, u, щ, i, ε/). Subjects' readings were recorded by NasalView and analyzed by Praat. Results showed that the means of F0 were significantly higher in the hearing impaired group than in the normal hearing group; in the female group than in the male group; and in high vowels than in low vowels. Second, intensity was significantly higher in the hearing impaired group than in the normal hearing group; in the female group than in the male group; and in low vowels than in high vowels. Third, jitter was significantly higher in the normal hearing group than in the hearing impaired group; in the female group than in the male group; and in back vowels than in front vowels. Finally,shimmer was significantly higher in the CI group than in the normal hearing group or the hearing aided group; in the male group than in the female group; and in low vowels than in high vowels.
