The aim of this study is to validate an aid for the evaluation of dysphonia with objective measurements. We recorded exhaled airflow, fundamental frequency and sound level pressure, for a sustained vowel "a", with 51 dysphonic subjects and 15 normal subjects. The following measurements are made on these three parameters: mean value, standard deviation and coefficient of variation. The exhaled airflow volume was also computed for a duration of 2 seconds. A principal components analysis of the measurements indicated that it is possible to recognise the classes of vocal evaluation and vocal pathology. These findings reinforce on objective aid for the vocal evaluation of dysphonia.
本研究的目的是通过客观测量来验证一种用于评估发声障碍的辅助工具。我们记录了51名发声障碍受试者和15名正常受试者发持续元音“a”时的呼气气流、基频和声压级。对这三个参数进行了以下测量：平均值、标准差和变异系数。还计算了2秒时长内的呼气流量。对测量结果进行的主成分分析表明，有可能识别出声带评估和声带病理的类别。这些发现强化了对发声障碍进行客观声带评估的辅助工具。
