本研究的目的是确定使用感知评级评估声带结节或息肉患者语音质量的有效性和可靠性。一个13维的感知评级系统是仿照目前在临床使用的系统。为了满足80%的平均interjudge的可靠性的标准，八个小时的培训，需要四个以前没有经验的听众。扩展元音发音的患者和对照组，然后由相同的听众盲目。在病理发声中判断的三个维度的判断者间信度大于0.90，而在五个维度上的判断者内重测一致性小于75%。通过使用所有维度计算判别函数，证明了100%正确分配至组的有效性。尽管使用了广泛的培训程序，我们的可靠性数据是不可比的，当经验丰富的法官已被使用，这表明感知评级语音质量的任务是困难的，需要丰富的专业经验。
The purpose of this study was to determine the validity and reliability of using perceptual ratings for assessing voice quality in patients with vocal fold nodules or polyps. A 13-dimension perceptual rating system was modeled after systems currently in clinical use. To meet the criterion of 80% mean interjudge reliability, eight hours of training were required for four previously inexperienced listeners. Extended vowel phonations of patients and controls were then rated blindly by the same listeners. Interjudge reliability was greater than .90 for three dimensions judged in the pathological phonations, while intrajudge test-retest agreement was less than 75% on five dimensions. Validity was demonstrated with 100% correct assignment to group by computing a discriminant function employing all dimensions. Despite the extensive training procedures used, our reliability data were not comparable to those reported when highly experienced judges have been used, suggesting that the task of perceptually rating voice quality is difficult and requires extensive professional experience.
