Cerebellar voice tremor: an acoustic analysis.
Patients with cerebellar disease may exhibit tremulous phonation as part of their dysarthria. The results of an acoustic analysis of cerebellar voice tremor in a patient with hereditary ataxia and presenting with a purely cerebellar syndrome are reported. Analysis included computation of speech intensity contours, fundamental frequency contours, and spectral parameters from sustained production...
متن کاملAcoustic Voice Measures in Benign Mass Lesions
Objectives: The present study aims to compare acoustic voice parameters in patients with vocal cord nodules, polyps, and normal subjects. Methods: In this cross-sectional case-control study, the participants were selected by convenience sampling, including 30 patients with vocal polyps group, 38 patients with vocal nodules for the second group, and 42 participants without voice pathologies a...
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...

The National Center for Voice and Speech is a multi-site, interdisciplinary organization dedicated to delivering state-of-the-art voice and speech research to practitioners, trainees and the general public. Members of the consortium are The Univer-A workshop was held on the 17th and 18th of February, 1994, in Denver, Colorado to reach better agreement on purpose and methods of acoustic analysis...
متن کاملAn 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...
