Speech Prosody 2004
We are investigating acoustical analysis for dysarthric speech, which appears as a symptom of neurologic disease, in order to elucidate its physiological and acoustical mechanism, and to develop aids for diagnosis and training, etc. In this report, acoustical characteristics of various kinds of dysarthrias are measured. As a result, shrinking of the F0 range as well as vowel space are observed in dysarthric speech. We performed a perceptual experiment to clarify how such parameters affect so-called "monotonous" impression, and found that abnormality in the F0 range affects the monotonous impression.
