In search of an objective method for the evaluation of vocal function it was investigated, whether there exists a relationship between the capability of kinesthetic phonatory control, i.e. the operational efficiency of the neuromuscular phonatory control system, and the quality of vocal function. In three groups of subjects with different quality of vocal function (singers, normal subjects and dysphonic patients) pitch and intensity changes of the speaking and singing voice during interruption of auditory feedback (by means of binaural maskings) were measured by means of fundamental frequency analysis. Results showed a much better kinesthetic control ability in singers than in normals and especially in dysphonic patients thus revealing, that the measurement of this ability can be used for evaluating individual vocal function objectively. The main evaluation criteria are: the degree of vocal pitch elevation while speaking under masking conditions, the accuracy of the singing voice without auditory control and the width of pitch perturbations of a sustained voice.
为了寻找一种评估嗓音功能的客观方法,研究了动觉发声控制能力(即神经肌肉发声控制系统的运行效率)与嗓音功能质量之间是否存在关联。通过基频分析,对三组嗓音功能质量不同的受试者(歌手、正常人和发声障碍患者)在听觉反馈中断(通过双耳掩蔽)期间的言语和歌唱嗓音的音高和强度变化进行了测量。结果表明,歌手的动觉控制能力比正常人尤其是发声障碍患者要好得多,从而表明这种能力的测量可用于客观评估个体嗓音功能。主要评估标准为:掩蔽条件下说话时嗓音音高升高的程度、无听觉控制时歌唱嗓音的准确性以及持续嗓音的音高扰动幅度。
