The Dysphonia Severity Index (DSI) and the Acoustic Voice Quality Index (AVQI) have been successfully investigated to quantify voice quality. The aim of the present study was to evaluate the diagnostic accuracy of both measurements in comparison with the dysphonia classification.
In total, 264 subjects with vocally healthy voices (n = 105) and with various voice disorders (n = 159) were included in the study. To determine the dysphonia classification, all subjects underwent a videolaryngostroboscopy and, if necessary, a direct microlaryngoscopy plus a clinical examination to diagnose a voice disorder. Patients with a vocally healthy voice had no actual voice complaints, no history of chronic laryngeal diseases or voice disorders, no hearing problems and were determined as healthy voices by clinical voice specialists. To evaluate the diagnostic accuracy, receiver operating characteristic statistics and correct classification rate (CCR) were used.
The diagnostic accuracy of DSI and AVQI showed strong sensitivity and specificity in the determination of dysphonia classification. A DSI threshold of 3.05 obtained a high sensitivity of 94.3% and specificity of 84.3%. An CCR of 88% was determined for DSI. Also, an AVQI threshold of 3.31 showed reasonable sensitivity of 71.7% and specificity of 88%. The CCR for AVQI was 79%.
Although DSI and AVQI were developed to quantify voice quality, the present results showed that both measurements can evaluate the dysphonia classification as well. Particularly, the DSI might have higher potential in the evaluation of dysphonia classification.

已成功研究了嗓音障碍严重程度指数（DSI）和嗓音声学质量指数（AVQI）来量化嗓音质量。本研究的目的是评估这两种测量方法与嗓音障碍分类相比的诊断准确性。
本研究共纳入264名受试者，其中嗓音健康者（n = 105）和患有各种嗓音障碍者（n = 159）。为确定嗓音障碍分类，所有受试者均接受了视频喉镜频闪检查，必要时进行直接显微喉镜检查及临床检查以诊断嗓音障碍。嗓音健康的患者无实际嗓音问题，无慢性喉疾病或嗓音障碍病史，无听力问题，且经临床嗓音专家判定为嗓音健康。为评估诊断准确性，采用了受试者工作特征统计和正确分类率（CCR）。
DSI和AVQI的诊断准确性在嗓音障碍分类的判定中显示出较高的敏感性和特异性。DSI阈值为3.05时，敏感性高达94.3%，特异性为84.3%。DSI的CCR为88%。此外，AVQI阈值为3.31时，敏感性为71.7%，特异性为88%，具有一定合理性。AVQI的CCR为79%。
尽管DSI和AVQI是为量化嗓音质量而开发的，但目前结果表明这两种测量方法也可评估嗓音障碍分类。特别是，DSI在嗓音障碍分类评估中可能具有更高的潜力。
