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.
记录了60名儿童的音高和强度范围，并绘制在嗓音范围剖面图（VRP）中。研究了不同方面：最小发声阈值、音高范围和最大动态范围。通过喉镜检查确定声带状态。10%的儿童有声带小结，23%有喉室裂隙。七位嗓音专家在两个不同场合听取了录制的声音，并根据包括嘶哑在内的16个参数对声音特性进行评分。两次录音中均有14%被评为嘶哑，因此被归类为慢性嘶哑。发现患有慢性嘶哑、声带小结和喉室裂隙的儿童在VRP特征上偏离正常。总体而言，与成年人相比，儿童的VRP轮廓似乎有所压缩，这反映了其发声动态能力受限；然而，有变声问题的儿童的VRP上部轮廓接近成年人。
