The Effects of Size and Type of Vocal Fold Polyp on Some Acoustic Voice Parameters

Background: Vocal abuse and misuse would result in vocal fold polyp. Certain features define the extent of vocal folds polyp effects on voice acoustic parameters. The present study aimed to define the effects of polyp size on acoustic voice parameters, and compare these parameters in hemorrhagic and non-hemorrhagic polyps.Methods: In the present retrospective study, 28 individuals with hemorrha...

Acoustic 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...

Auto-meshing algorithm for acoustic analysis of vocal tract

We propose a new method for an auto-meshing algorithm for an acoustic analysis of the vocal tract using the Finite Element Method (FEM). In our algorithm, the domain of the 3 dimensional figure of the vocal tract is decomposed into two domains; one is a surface domain and the other is an inner domain in order to employ the overlapping domain decomposition method. The meshing of surface blocks c...

Comparative analysis of perceptual evaluation , acoustic analysis and indirect laryngoscopy for vocal assessment of a population with vocal complaint Summary

Acoustic and perceptual analysis of vocal registers in children

According to Hirano, Kurita and Nakashima (1983) the vocal fold structure changes continuously from earliest childhood to late adolescence. During pubert), the elastic fibers are differentiated from the deeper collagenous fibers. These changes can be assumed to affect the vocal register function. The pitches at which register transitions occurred were identified perceptually in recordings of 15...
