• This paper deals with a system of prosody assessment. The subjects were 2 patients with ataxic dysarthria and 10 normal speakers. They were given contrastive stress tasks as speech samples. Accuracy of prominence and bizarreness of speech were perceptually judged, and patterned variations of fundamental frequency, duration and intensity were then acoustically analyzed. The major results included the following.<BR>(1) Accuracy of prominence in normal speakers was rated quite high. They tended to use increases in fundamental frequencies, duration and intensities to signal prominence.<BR>(2) Accuracy of prominence in patient 1 was rated very changeable depending on the sentences. She tended to use increases in fundamental frequencies and duration to signal prominence. Accuracy of prominence in patient 2 was rated very low. He was unable to adjust any acoustic parameters functionally.<BR>(3) Acoustic information was useful to analyze inaccuracy of prominence and bizarreness of speech perceived in the 2 dysarthric speakers.<BR>In addition, clinical use of the prosody assessment system for planning treatment was discussed.
