ABSTRACT |
children with cochlear implant (CI) comparing that of children with normal hearing and to verify the effects of voice therapy on improving the hypernasality observed in CI children . Methods The nasalance scores of 7 Korean vowels (/a, ʌ, o, u, ɯ, i, ɛ/) pronounced by 10children with CI (G1) and 10 children with NH (G2) matching sex and chronological age were measured by Dr. Speech. Voice therapy was performed 2 times a week and 40 minutes a session during 8 weeks. Their nasalance scores were measured 3 times (before and after 4 and 8 weeks of the training). Results Results of nasalance value of children with CI were as follows: means of nasalance scores of G1 (CI) were significantly higher than those of G2 (NH) in all 7 vowels (p < .05). Means of high vowels were significantly higher than those of low vowels in both groups (p < .05). The result of voice therapy showed that there were significant differences in nasalance scores in all 7 vowels (p < .05). Discussion & Conclusion Participants in thisstudy were implanted over the age 5 and have used the device more than 2 years. Although they have improved auditory feedback through CI, their voice were evaluated as being hypernasal. After voice therapy, nasalance scores were decreased to the range of children with normal hearing. |
