Talk Title: Vocal Tremor Analysis Using the Fine Structure Spectrogram
Slides: 7-1.ppt
Abstract: Tremor is an unintentional muscle movement involving oscillations of one or more parts of the body. Vocal tremor is known to be associated with neurological disorders such as Parkinson’s disease, essential tremor, and cerebellar ataxia. These vocal tremors are associated with a low-frequency modulation of the vocal folds. Characterizing the frequency, level and intensity of these modulations may help in diagnosing and treating a disorder. While much work towards measuring the variation of the pitch contour using time domain techniques has been done, these methods are not able to classify abnormal phonations accurately. By employing a two-stage method involving time-frequency analysis using the Fine Structure Spectrogram (FSS), it may be possible to create a more robust classifier that is suitable for a clinical environment.
