Perceptual evaluation was performed by means of the GRBAS scale for a series of nine pathological voice samples that were presented twice to a group of 23 judges, consisting of experienced and inexperienced otolaryngologists (ENTs) and speech-language pathologists (S/LPs). The time interval between ratings was 14 days. Test-retest reliability was moderate. The best agreement between the observers was obtained for the G (grade) parameter and the worst for the S (strained) parameter. Considering the medians of the GRBAS ratings, no significant influence was measured for level of experience or professional background. Yet, based on means, the results show that professional background has a greater impact on perceptual rating than experience.
通过GRBAS量表对一系列九个病理性嗓音样本进行了感知评估，这些样本向由经验丰富和经验不足的耳鼻喉科医生（ENTs）和言语语言病理学家（S/LPs）组成的23名评判员展示了两次。评分之间的时间间隔为14天。重测信度为中等。观察者之间在G（等级）参数上的一致性最好，在S（紧张）参数上的一致性最差。考虑到GRBAS评分的中位数，未发现经验水平或专业背景有显著影响。然而，基于平均值，结果表明专业背景对感知评分的影响大于经验。
