The study is designed to examine hypernasality reductions and transfer effects when the visual biofeedback program by a nasometer (Model 6200-3,Kay)has been performed to cleft palate and lip children. Three cleft palate and lip children were taken as subjects. The subjects were normal in intelligence, hearing, eyesight and visual perception. They didn't also show complete veloharyngeal incompetence innately. A fifty minute session was taken four times a week. I applied the phonetic contents program developed by myself to each subject. This program was made to go through a warm-up step for each target sound and ...
The study is designed to examine hypernasality reductions and transfer effects when the visual biofeedback program by a nasometer (Model 6200-3,Kay)has been performed to cleft palate and lip children. Three cleft palate and lip children were taken as subjects. The subjects were normal in intelligence, hearing, eyesight and visual perception. They didn't also show complete veloharyngeal incompetence innately. A fifty minute session was taken four times a week. I applied the phonetic contents program developed by myself to each subject. This program was made to go through a warm-up step for each target sound and CV, VCV,CVC steps. To make hypernasality clear, I designed a multiful baseline across subjects. To know pre-post therapy, I made a pre-post design. The results of the study were as follows; First, after I performed the visual biofeedback program by a nasometer to my subjects, the nasalance of subject A decreased from 45.74% to 33.12%. The nasalance of subjects B and subject C decreased from 46.27% to 31.54% and from 33.42% to 14.64% respectively. Second, after I examined the hypernasality improvement in a word level, I found that the nasalance of subject A was reduced to 8.29% and that of subjects B and C was reduced to 10.31% and 12.31% respectively. Third, after I examined whether there were transfer effects of the hypernasality improvement in untrained phonemes(/ㅁ,ㄴ,ㅇ/), I found that the nasalance of subject A decreased to 7.26%, and that of subjects B and C decreased to 9.53% and 8.68% respectively. The conclusions of the study are as follows: First, the visual biofeedback program by a nasometer had an effect on cleft palate and lip children. Second, the visual biofeedback program by a nasometer had an effect on the hypernasality improvement in a word level. Third, the visual biofeedback program by a nasometer had an effect on the hypernasality improvement in untrained phonemes(/ㅁ,ㄴ,ㅇ/).
