The purpose of the present study was to analyze and describe the characteristics of speech in dysarthric patients diagnosed as idiopathic Parkinsonism, based on auditory impressions.<BR>Eight judges independently rated each of speech samples of 34 patients on each of 39 dimensions of speech using a 4-point scale of severity. The results were as follows;<BR>1) Speech of the patients was characterized by those dimensions such as“imprecise consonants”, “harsh voice”, “breathy voice”and“phoneme repeated”.<BR>2) In comparison with previous reports on the speech characteristics of cerebellar diseases, pseudobulbar palsy and amyotrophic lateral sclerosis, the severity of Parkinsonian dysarthria is considered to be relatively mild. It should also be noted that Parkinsonian dysarthria was the only type in which slow rate of speech was insignificant.<BR>3) The present results showed a considerable discrepancy when compared with those reported by Darley et al., who conducted a similar study on American English speakers. It was considered that the discrepancy might be due either to the remarkable progress in medical treatment for Parkinsonism during the ten years after the report of Darley et al, or to the linguistic difference between the two languages. On the other hand, quite similar results were obtained for comparable items of a previous report on Japanese patients by Hirose.
