An acoustic-perceptual study of vocal tremor.
BACKGROUND Essential tremor of the voice (ETV) is an involuntary intention tremor of the vocal folds that causes fluctuations in fundamental frequency (f(0)) and/or intensity leading to an unsteady voice. There is limited data on how different acoustic variables affect perception of severity of tremor. AIM The purpose of the study was to determine if systematic changes in f(0), rate or modula...
متن کاملEffect of Parkinson's disease on vocal tremor
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...
متن کاملAcoustic and perceptual analysis of vocal tremor
The objective is to present a method to analyze vocal tremor in sustained speech sounds and compare the results with a perceptual scoring of the degree of tremor. The vocal cycle lengths are tracked by salience analysis and dynamic programming. The cycle length time series is then split into three components by empirical mode decomposition: jitter, tremor and trend. Tremor cues are obtained via...
متن کاملResting tremor classification and detection in Parkinson's disease patients
Parkinson is a neurodegenerative disease, in which tremor is the main symptom. This paper investigates the use of different classification methods to identify tremors experienced by Parkinsonian patients. Some previous research has focussed tremor analysis on external body signals (e.g., electromyography, accelerometer signals, etc.). Our advantage is that we have access to sub-cortical data, w...
متن کاملThe Distribution and Severity of Tremor in Speech Structures of Persons with Vocal Tremor.
BACKGROUND Vocal tremor may be associated with cyclic oscillations in the pulmonary, laryngeal, velopharyngeal, or oral regions. OBJECTIVES This study aimed to correlate the overall severity of vocal tremor with the distribution and severity of tremor in structures involved. METHODS Endoscopic and clinical examinations were completed on 20 adults with vocal tremor and two age-matched contro...
