Abstract

|
|
The purpose of this study is to investigate the differences of the speech rate according to the area in the perceptual andacoustic analysis. This study examines regional variation in overall speech rate and articulation rate across speaking situations(picture description, free conversation and story retelling) with 14 normal adult (7 in Gyeongnam and 7 in Honam area). The result of an experimental investigation shows that the perceptual speech rate differs significantly between two regionalvarieties of Koreans with a picture description examined here. A group of Honam speakers spoke significantly faster than agroup of Gyeongnam speakers. However, the result of the acoustic analysis shows that the speech rate of the two groups didnot differ. And there were significant regional differences in the overall speech rate and articulation rate on the other twospeaking situation, free conversation and story retelling. It suggest that we have to study perceptual evaluation with regard tothe free conversation and story retelling in future research, and based on the results of this study, a variety of researches onthe speech rate will be needed on the various conditions, including various area and SLPs who have wider background andexperiences. It is necessary for SLPs to train and experience more to assess patients properly and reliably.
