Abstract

The purposes of this study were to investigate the characteristics of speech rate and pause in patients with flaccid dysarthria. For this purpose, 15 patients with flaccid dysarthria and 15 normal speakers matched in gender and age participated as subjects. The overall speech rate, the articulation rate, the inter-sentence and the intra-sentence pause duration and pause frequency were measured during reading the standardized passage "Autumn"(Kim, 1996). As a result, the overall speech rate and articulation rate of patients with flaccid dysarthria were significantly slower than normal speakers and intra-sentence pause duration and frequency of patients with flaccid dysarthria were significantly higher than normal speakers, but those of inter-sentence weren't. The results from this study provides the speech rate index of flaccid dysarthria and indicates that to control the speech rate of flaccid dysarthria have regard to not only the overall speech rate and the articulation rate but also the intra-sentence pause duration and the frequency.
