초록

The purpose of this study is to evaluate the association among articulation rate, speech intelligibility and working memory in children with dysarthria. Two subject groups of 11 spastic and 11 flaccid dysarthria, respectively, aged between 8 and 17 years of age participated in this study. All participants were administered the following tests: K-WISC III PIQ test, speech intelligibility, working memory and articulation rate. Group differences were compared by an independent t-test. Pearson correlation were computed between all measures. The results of this study are as follows: First, speech rate and intelligibility were significantly lower for the spastic dysarthria than for the flaccid dysarthria. Second, there was a significant correlation between articulation rate and intelligibility in children with flaccid dysarthria. Lastly, there was no significant correlation between articulation rate and working memory in both groups. The results suggest that articulation rate is not necessarily accompanied by working memory capacity in children with dysarthria, and there are differences in the effect of articulation rate on intelligibility depending on the type of dysarthria.
