A standardized, perceptually based description of hoarseness is of importance for clinical purposes (e.g. therapy evaluation) as well as in research on voice disorders. The reliability and relevance of perceptual parameters are investigated. The GRBAS scale parameters quite well fit the criteria: low intrajudge and interjudge variance but high intervoice variance. The best correlation between judges (0.7) is found for the overall grade of severity. Impressions of the asthenic-strained voice quality are less consistent, but still show a significant interjudge correlation. The overall grade of severity seems to be mainly determined by the component breathiness. Roughness and breathiness are negatively correlated with each other. Tonus is correlated neither with roughness nor breathiness. The GRBAS profiles significantly differ between the different pathological groups.
对于临床目的（如治疗评估）以及嗓音障碍研究而言，基于感知的标准化声音嘶哑描述至关重要。研究了感知参数的可靠性和相关性。GRBAS量表参数相当符合标准：评判者内和评判者间方差低，但声音间方差高。在总体严重程度等级方面，评判者之间的最佳相关性为0.7。对无力紧张型嗓音质量的印象一致性较差，但评判者间仍显示出显著相关性。总体严重程度等级似乎主要由气息声成分决定。粗糙度和气息声彼此呈负相关。音调与粗糙度和气息声均无相关性。不同病理组之间的GRBAS特征存在显著差异。
