The aim of the present study is to validate the Acoustic Voice Quality Index version 03.01 in the Italian language (AVQIv3-IT).
A total of 150 native Italian speakers with normal voices (n = 50) and with various voice disorders (n = 100) were enrolled. Voice samples of a sustained vowel (SV) [a:] and five phonetically balanced continuous speech (CS) samples were recorded. The most appropriate syllable number for a standardized voiced CS approximating 3 seconds was identified. Perceptual evaluations of the overall voice quality were performed by three expert voice clinicians using the G score of the GRBAS scale. AVQIs were calculated using a 3 seconds mid-vowel selection of the SV [a:] and the standardized syllable number of the CS. Finally, concurrent validity and diagnostic accuracy of AVQIv3-IT were analysed.
The most appropriate syllable number for a standardized CS approximating 3 seconds in Italian was identified as 25. The perceptual ratings showed robust intra- and inter-rater reliability. A strong correlation was found between AVQI scores and overall voice quality perceptual evaluations (r = 0.81, P < 0.001). The best diagnostic outcome for AVQIv3-IT was found for a threshold of 2.35 (sensitivity of 90% and specificity of 92%).
AVQIv3-IT was demonstrated to be a valid and robust tool for quantifying overall acoustic voice quality in the Italian speaking population.
本研究旨在验证意大利语版的声学语音质量指数（AVQIv3-IT）。
共纳入 150 名母语为意大利语、嗓音正常的受试者（n=50）和患有各种嗓音障碍的受试者（n=100）。记录受试者发持续[a:]元音和 5 个语音平衡的连续言语样本。确定最适合标准化浊音连续言语（CS）接近 3 秒的最佳音节数。三位专家嗓音临床医生使用 GRBAS 量表的 G 评分对整体嗓音质量进行感知评估。使用 SV[a:]的 3 秒中间元音选择和 CS 的标准化音节数计算 AVQIs。最后，分析了 AVQIv3-IT 的同时效度和诊断准确性。
确定了最适合意大利语 3 秒左右标准化 CS 的最佳音节数为 25。感知评分显示出较强的内部和内部一致性。AVQI 评分与整体嗓音质量感知评估之间存在很强的相关性（r=0.81，P<0.001）。AVQIv3-IT 的最佳诊断结果为阈值为 2.35（灵敏度为 90%，特异性为 92%）。
AVQIv3-IT 被证明是一种在意大利语人群中评估整体声学嗓音质量的有效且可靠的工具。
