OBJECTIVE
To study the differences in perceptual ratings of mild and moderate dysphonia related to the speech task, and their impact on intrarater and interrater reliabilities.
PATIENTS AND METHODS
Voice recordings of 15 outpatients with mild or moderate dysphonia related to laryngopharyngeal reflux were presented to 6 female experienced judges blinded to the clinical state of the patients. From these, the GRBASI (Grade, Roughness, Breathiness, Asthenia, Strain, and Instability) evaluations were performed on connected speech and sustained vowel of the pretreatment voice recordings and absolute agreement, and both intrarater and interrater reliabilities were assessed.
RESULTS
The average GRBASI scores were significantly worse when performed on sustained vowel. Intrarater reliability substantially varied according to the judge and the task. Good interrater reliability was broadly found for the evaluations of all GRBASI components irrespective of the speech task. Concerning agreement, we only found absolute agreement between judges for G and R items assessed on text.
CONCLUSION
Average grade of perceptual voice impairment, intrarater reliability, and agreement vary according to the speech task.
目的
研究与言语任务相关的轻度和中度发音障碍的感知评分差异，以及它们对评分者内和评分者间信度的影响。
患者与方法
将15例与喉咽反流相关的轻度或中度发音障碍门诊患者的语音录音呈现给6名对患者临床状态不知情的经验丰富的女性评判员。从中，对预处理语音录音的连贯言语和持续元音进行GRBASI（分级、粗糙度、气息声、无力、紧张和不稳定性）评估，并评估绝对一致性以及评分者内和评分者间信度。
结果
对持续元音进行评估时，GRBASI平均得分显著更差。评分者内信度根据评判员和任务的不同有很大差异。无论言语任务如何，对所有GRBASI成分的评估都广泛发现了良好的评分者间信度。关于一致性，我们仅发现评判员对文本中评估的G项和R项达成了绝对一致。
结论
感知性语音障碍的平均分级、评分者内信度和一致性因言语任务而异。
