在这项研究中，回顾性分析的临床语音干扰措施，发音困难的严重程度指数和主观感觉嘶哑，以确定其价值的临床方面。该研究包括580名健康人和1,700名病理嗓音的数据，从以下几个方面进行了调查。确定了相关参数，并确定了它们之间的相互关系。健康和病理的声音之间的组差异，找出和调查，如果语音质量的措施允许自动诊断的声音障碍。分析显示，临床组之间的显着变化，这表明语音质量指标的诊断相关性。然而，由于各组内参数值的巨大差异，对潜在语音障碍的个体诊断失败了。分类准确率达到75-90%。高达25%的高错误分类率意味着在嗓音障碍诊断中，必须仔细地对参数值进行个体解释。
Within this study a retrospective analysis of clinical voice perturbation measures, Dysphonia Severity Index and subjective perceived hoarseness was performed to determine their value under clinical aspects. The study included the data of 580 healthy and 1,700 pathologic voices, which were investigated under the following aspects. The relevant parameters were identified and their interrelation determined. Group differences between healthy and pathologic voices were figured out and investigated if voice quality measures allowed an automatic diagnosis of voice disorders. The analysis revealed significant changes between the clinical groups, which indicate the diagnostic relevance of voice quality measures. However, an individual diagnosis of the underlying voice disorder failed due to a vast spread of the parameter values within the respective groups. Classification accuracies of 75-90% were achieved. The high misclassification rate of up to 25% implied that in voice disorder diagnosis, the individual interpretation of the parameter values has to be done carefully.
