Abstract
|
|
|
|
The purpose of this study was to compare the acoustic properties of fricatives, /ㅅ, ㅆ/ produced by children with functional articulation disorder and normal children (N=20, aged 6-7). All subjects showed significant differences in both the length of friction intervals and breathing intervals of fricatives according to the changes in the environment presented within each group. However, there is a difference in the extent of variation in length between the two groups. This means that children with functional articulation disorder have greater difficulty in adjusting fricative noises according to changes in the CVㆍVCV environment than normal children.
