Fourth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2005)
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 Parkinsons disease and control speakers. It is shown that Parkinsons disease has significant effects on vocal tremor features. For speakers with Parkinsons 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.
