Abstract
Measurement of maximum duration of phonation has been suggested by several voice experts as a clinical tool for assessing vocal function (Arnold, 1955; Irwin, 1965; Yanagihara, Koike and von Leden, 1966; and Boone, 1971). Most of the investigations of maximum phonation time have been conducted using adult populations. exceptions to this can be found in the studies by Launer (1971) and Coombs (1976). An apparent need, therefore, existed to investigate maximum phonation time in children.
The present study was designed to investigate the affects of age, sex, height, weight and vital capacity on the maximum duration of phonation of sustained /a/ in children eight and ten years of age when controlling for pitch and intensity.
