Abstract

Measurement of maximum duration of phonation has been suggested by several voice experts as a clinical tool for assessing vocal function. 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. The essential questions were:

  • What is the relationship of the variables age, sex, vital capacity, height and weight to the duration of sustained /a/? 
  • Given twenty trials, does the maximum duration of sustained /a/ occur beyond the third trial?
