A comparison of the prosodic characteristics of the speech of people with Parkinson's disease and Friedreich's ataxia with neurologically normal speakers.
The realization of prosody (speech rate, fundamental frequency, intonation) was investigated in a group of 10 individuals with Parkinson's disease and a group of 10 individuals with Friedreich's ataxia. Data from these two neurologically disordered groups were compared to individuals without neurological impairment. Both neurologically impaired groups retained some aspects of normal speech prosody, while other aspects were affected to a significant degree. The prosodic characteristics of speakers with Parkinson's disease were distinct from those of speakers with Friedreich's ataxia. These results were interpreted in terms of prosodic competence and prosodic performance.
