Abstract
Pitch and intensity range of 60 children were recorded and plotted in voice range profiles (VRPs). Different aspects were investigated: minimum phonation threshold, pitch range, and maximum dynamic range. Vocal fold status was determined via laryngoscopic examination. Ten percent of the children had vocal nodules, 23% glottal chinks. Seven voice experts listened to the voices recorded on two separate occasions and rated their properties along 16 parameters including hoarseness. Fourteen percent were rated as hoarse on both recordings and were thus classified as being chronically hoarse. Departures from normal in VRP characteristics were found for children suffering from chronic hoarseness, nodules, and glottal chinks. Children in general seem to have somewhat compressed VRP contours compared with adults, reflecting restricted dynamic vocal capabilities; however, children with mutational voices exhibited an approximation to adult upper VRP contours.
