Rating scales to determine the severity of dysphonia have shown considerable inter-rater variability. The objective of this study, therefore, was to investigate a more quantitative measure to perceptually rate the severity of dysphonia. The study was conducted on 10 participants with abuse-related dysphonia in two conditions, spontaneous speech, and paragraph reading. Four speech-language pathologists, who had experience with voice disorders, and one trained student counted the frequency of the nondysphonic syllables during the above two conditions. The voice samples were both recorded and transcribed for simultaneous analysis. All the recordings were randomized when presented to the raters. The raters circled the nondysphonic syllables while listening to each participant's recording. The nondysphonic syllables were counted, and a percentage of dysphonic severity was calculated for each participant to obtain a dysphonic severity percentage. Specific characteristics (eg, breathiness, noise, strain) were not specifically addressed, as they were components of the percentage of dysphonia obtained. The Cronbach's alpha revealed very high inter-rater reliability and high correlations among the raters for both spontaneous speech and paragraph reading, indicating reduced variability in raters' perceptions. This method appeared to be a more quantitative measure of perceptual ratings than current scales, which use general gradations of dysphonic severity. In addition, a naïve rater was successfully trained to use this method. This technique has the potential to be used in both pre- and posttherapy analysis, as well as during therapy, to determine progress.
用于确定嗓音障碍严重程度的等级量表显示出相当大的评分者间变异性。因此，本研究的目的是探索一种更定量的方法来感知性地评估嗓音障碍的严重程度。该研究在 10 名因滥用导致的嗓音障碍患者中进行，分为两种情况，即自发言语和段落朗读。四名具有嗓音障碍经验的言语语言病理学家和一名经过培训的学生在上述两种情况下计算无嗓音障碍音节的频率。对嗓音样本进行了录音和转写，以便进行同步分析。所有录音在呈现给评分者时都是随机的。评分者在听每个参与者的录音时圈出无嗓音障碍音节。对无嗓音障碍音节进行计数，并计算每位参与者的嗓音障碍严重程度百分比，以获得嗓音障碍严重程度百分比。特定特征（如气息声、噪声、紧张）没有专门提及，因为它们是获得的嗓音障碍百分比的组成部分。Cronbach's alpha 显示，无论是在自发言语还是段落朗读的情况下，评分者之间的评分者间信度都非常高，并且评分者之间的相关性很高，这表明评分者的感知变异性降低。与目前使用嗓音障碍严重程度一般渐变的量表相比，这种方法似乎是一种更定量的感知评分测量方法。此外，一名未经训练的评分者成功接受了这种方法的培训。这种技术有可能用于治疗前和治疗后的分析，以及治疗期间，以确定进展情况。
