TL;DR
Objective measurement of vocal function is important in evaluating phonatory disorders, planning treatment, and documenting the effects of therapy and simultaneous recording of acoustic, photoglottographic and electroglottographic signals is being used in the evaluation of patients with voice disorders associated with neurologic impairments.
Abstract
Objective measurement of vocal function is important in evaluating phonatory disorders, planning treatment, and documenting the effects of therapy. Glottographic measurement, ie, measures that describe glottal movement, can be performed and analyzed relatively easily, and can be related to the pathophysiology of vocal dysfunction. In our clinic, simultaneous recording of acoustic, photoglottographic and electroglottographic signals is being used in the evaluation of patients with voice disorders associated with neurologic impairments. Our experience with these measures indicates that they may provide detailed information about the vibratory patterns of the vocal folds, which appears to differentiate some phonatory characteristics among patients with differing types of disorders.

The harmonics-to-noise (H/N) ratio proved useful in quantitatively assessing the results of treatment for hoarseness and showed a highly significant agreement between H/N calculations and the subjective evaluations of the spectrograms.

The middle segments of sustained phonations of /i/, produced by six male adults at fo's ranging from 98 to 298 Hz, were examined for cycle-to-cycle frequency perturbation and showed that, between 98 Hz and 210 Hz, mean jitter size decreased as the fo increased, whereas the corresponding jitter ratios remained relatively constant.
