Abstract

Kirsner, Dunn, Hird, Parkin and Clark (2002) described the lognormal pause and speech segment distributions which chracterize spontaneous speech. This project investiagted the ecological validity of a pause distribution approach to classification of aphasia. The relationship between acoustic measures derived from 8 aphasic speech samples and 22 naive listener's similarity judgments using multidimensional scaling analysis and direct magnitude estimates of fluency was undertaken. Listener's descriptions of the speech samples were subject to lexical semantic analysis and semantic concept analysis. The results indicated a relationship between the temporal characteristics and listener's perception of similarity and fluency.
