Hoarseness, Speech disorders in children
Hoarseness seems to be the primary type of voice disorder occurring in school-aged children. Voice experts have suggested measurement of maximum phonation times as a clinical tool for assessing vocal function (Fairbanks, 1940; Westlake and Rutherford, 1961; Irwin, 1965; Boone, 1971). Most of the studies on duration of phonation have used adults as subjects; few investigations have involved children. An apparent need, therefore, existed to investigate duration of phonation in young children.
