一个由五名儿童声音专家组成的小组在15名10岁儿童的录音中识别了音域转换，这些儿童在整个发音范围内以不同的音调保持元音[a：]。其中2人的声音发生突变，7人的声音异常，6人的声音正常。控制组的平均基频为511赫兹，有一个音域转换，比成人的声音高出约25%。成人和儿童声音之间的差异可能是由于气管长度的差异，正如Tize所提出的(J.Voice 1988；3：183-194)。有功能性或生理性发音偏差的儿童表现出平均频率为417赫兹的转变。在平均频率为902赫兹的四个声音中发现了第二个转变。在音域转换的发生和上、下音域轮廓的不连续之间没有发现相关性。
Register transitions were identified by a group of five experts on child voices in recordings of 15 10-year-old children who sustained the vowel [a:] at different pitches throughout their vocal range. Two had mutational voices, seven had deviant voices and six were controls with normal voices. The control group had one register transition at a mean fundamental frequency of 511 Hz, or about 25% higher than in adult voices. This difference between adult and child voices may be because of the difference in trachea length, as proposed by Titze (J. Voice 1988; 3: 183-194). Children with either functional or physiological voice deviations exhibited a transition at a mean frequency of 417 Hz. A second transition was found in four voices at a mean frequency of 902 Hz. No correlation was found between the occurrence of register transitions and discontinuities in the upper and lower voice range profile contours.
