OBJECTIVES/HYPOTHESIS: This study aimed to validate the acoustic voice quality index version 03.01 (AVQIv3) and the acoustic breathiness index (ABI) in the Persian language.
Six judges assessed the severity degree of the abnormal overall voice quality (hoarseness) and breathiness from continuous speech (cs) and sustained vowel (sv) in 136 voices samples of dysphonic and 45 vocally healthy participants. Firstly, the time length of cs and sv was balanced out for a higher level of ecological validity. Secondly, the concurrent validity and diagnostic accuracy were statistically analyzed with the Spearman rank-order correlation, and the receiver operating characteristics, likelihood ratio, and Youden index.
There was substantial inter-rater reliability between judges regarding hoarseness and breathiness. Twenty syllables were identified as the standardized number of syllables for the cs part. Sufficient correlations were found between AVQI and hoarseness (r = 0.74), and between ABI and breathiness (r = 0.74), respectively. The thresholds of 1.63 (sensitivity of 73.2% and specificity of 91%) and 2.97 (sensitivity of 70% and specificity of 87%) yielded the highest level of diagnostic findings for AVQI and ABI, respectively.
The AVQIv3 and ABI are reliable indices to quantify the abnormal overall voice quality and breathiness in the Persian language.
目的/假设：本研究旨在验证波斯语版的声学嗓音质量指数03.01版（AVQIv3）和声学呼吸音指数（ABI）。
六名评判员对136名嗓音障碍参与者和45名嗓音健康参与者的连续语音（cs）和持续元音（sv）中的异常总体嗓音质量（嘶哑）和呼吸音严重程度进行评估。首先，为了提高生态效度，对cs和sv的时长进行了平衡。其次，采用Spearman等级相关、受试者工作特征曲线、似然比和尤登指数对同时效度和诊断准确性进行统计学分析。
评判员之间在嘶哑和呼吸音方面具有较高的评分者间信度。确定20个音节为cs部分的标准化音节数。分别在AVQI与嘶哑之间（r = 0.74）以及ABI与呼吸音之间（r = 0.74）发现了充分的相关性。AVQI和ABI的诊断结果分别在阈值为1.63（灵敏度为73.2%，特异度为91%）和2.97（灵敏度为70%，特异度为87%）时达到最高水平。
AVQIv3和ABI是量化波斯语中异常总体嗓音质量和呼吸音的可靠指标。
