The Acoustic Voice Quality Index (AVQI) is a multivariate construct for quantification of overall voice quality based on the analysis of continuous speech and sustained vowel. The stability and validity of the AVQI is well established in several language families. However, the Japanese language has distinct characteristics with respect to several parameters of articulatory and phonatory physiology. The aim of the study was to confirm the criterion-related concurrent validity of AVQI, as well as its responsiveness to change and diagnostic accuracy for voice assessment in the Japanese-speaking population.
This is a retrospective study.
A total of 336 voice recordings, which included 69 pairs of voice recordings (before and after therapeutic interventions), were eligible for the study. The auditory-perceptual judgment of overall voice quality was evaluated by five experienced raters. The concurrent validity, responsiveness to change, and diagnostic accuracy of the AVQI were estimated.
The concurrent validity and responsiveness to change based on the overall voice quality was indicated by high correlation coefficients 0.828 and 0.767, respectively. Receiver operating characteristic analysis revealed an excellent diagnostic accuracy for discrimination between dysphonic and normophonic voices (area under the curve: 0.905). The best threshold level for the AVQI of 3.15 corresponded with a sensitivity of 72.5% and specificity of 95.2%, with the positive and negative likelihood ratios of 15.1 and 0.29, respectively.
We demonstrated the validity of the AVQI as a tool for assessment of overall voice quality and that of voice therapy outcomes in the Japanese-speaking population.
声学嗓音质量指数（AVQI）是一种基于连续语音和持续元音分析来量化整体嗓音质量的多变量指标。AVQI的稳定性和有效性在多个语系中已得到充分确立。然而，日语在发音和发声生理学的几个参数方面具有独特特征。本研究的目的是确认AVQI与标准相关的同时效度，以及其在说日语人群中对嗓音变化的反应性和嗓音评估的诊断准确性。
这是一项回顾性研究。
共有336份嗓音录音符合研究条件，其中包括69对（治疗干预前后）嗓音录音。由五名经验丰富的评估者对整体嗓音质量进行听觉感知判断。评估了AVQI的同时效度、对变化的反应性和诊断准确性。
基于整体嗓音质量的同时效度和对变化的反应性分别由高相关系数0.828和0.767表明。受试者工作特征分析显示，在区分嗓音障碍和正常嗓音方面具有出色的诊断准确性（曲线下面积：0.905）。AVQI的最佳阈值水平为3.15，对应灵敏度为72.5%，特异度为95.2%，阳性似然比和阴性似然比分别为15.1和0.29。
我们证明了AVQI作为评估说日语人群整体嗓音质量和嗓音治疗效果工具的有效性。
