Effect of Parkinson’s disease on vocal tremor

L. Cnockaert, Jean Schoentgen, P. Auzou, C. Ozsancak, Francis Grenez

Vocal tremor is encountered in different neurological diseases and could be used for their characterisation. In this paper, vocal tremor features have been extracted for speakers with Parkinson’s disease and control speakers. It is shown that Parkinson’s disease has significant effects on vocal tremor features. For speakers with Parkinson’s disease, the average vocal frequency is higher and the vocal tremor frequency is higher. This can be explained by higher vocal tremor components in the frequency band 8-12Hz.
