Abstract
An implicit assumption in voice perturbation analysis is that one is dealing with small random variations in fundamental frequency and amplitude. However, many irregularities in voiced speech are not necessarily small or random (e.g., subharmonics, amplitude modulations, frequency modulations, linear trends). In this study, various processing schemes are employed to detect/remove trends and subharmonics from fundamental frequency and amplitude contours. Voice perturbation measures are calculated before and after application of the detection/removal techniques. Separating trends and subharmonics from random perturbations in voice analysis may prove useful in classifying and identifying voice disorders. Results of analysis on a variety of subjects will be presented.
