Abstract

|
|
The purpose of this study is to examine the prosodic pattern of the children with high functioning autism spectrum disorder(HFASD) according to sentence type. The participants were 18 children aged from 7 - 9 years; 9 children with HFASD and 9 typical development children(TD) of the same chronological age with HFASD children. Sentence reading tasks were conducted in this study. Seven interrogative sentences and 7 declarative sentences were presented to the participants and were asked to read the sentences three times. Mean values of F0, F0 range, intensity, speech rate and pitch contour were measured for each sentence. The results showed that for F0 range, significant main effect and interaction effect were observed in the subject group and sentence type. There were significant differences in intensity, mean F0, speech rate, pitch contour across sentence types. The results of this study indicated that HFASD showed no difference in intonation across sentence types. Speakers’ intention may have a negative effect on pragmatic aspects. These results suggest that the assessment and intervention of prosody be important for HFASD.
