The aim of the present study was to investigate the validity (both concurrent and diagnostic) and test-retest reliability of Acoustic Voice Quality Index (AVQI) version 2 (AVQI 02.06) in Turkish speaking population.
Two hundred and fifty five native Turkish subjects with normal voices (n = 128) and with voice disorders (n = 127) were asked to sustain the vowel [a:] and read aloud the Turkish phonetically balanced text. To determine the test-retest reliability of AVQI, 20 dysphonic (ie, around 15% of the group), and 20 normophonic (ie, around 15% of the group) were reassessed 15 minutes after the first AVQI determination. A three middle seconds of sustained vowel [a:] and a sentence with 25 syllables was concatenated, and AVQI analysis was conducted. The auditory-perceptual evaluation was performed by five experienced raters with Grade (G) from GRBAS Protocol.
There was a statistically significant correlation between AVQI scores and auditory-perceptual evaluation of overall voice quality (r = 0.717, P < 0.001). AVQI gave a threshold of 2.98 for the dysphonic voice. The values of intraclass correlation coefficient with two-way mixed-effects model, single-measures type, absolute agreement definition showed an excellent test-retest reliability for AVQI in Turkish language (intraclass correlation coefficient = 0.986).
AVQI v.02.06 is a valid and robust tool in differentiating dysphonic and normal voice, and has excellent test-retest reliability in Turkish language.
本研究旨在探讨土耳其语人群中声门关闭不全指数（AVQI）版本 2（AVQI 02.06）的效度（同时和诊断）和重测信度。
255 名母语为土耳其语、声音正常的受试者（n=128）和有嗓音障碍的受试者（n=127）被要求持续发[a:]元音并朗读土耳其语语音平衡文本。为了确定 AVQI 的重测信度，对 20 名发音障碍者（即组内的 15%）和 20 名发音正常者（即组内的 15%）在第一次 AVQI 测定后 15 分钟进行了重新评估。将持续发 3 秒钟的[a:]元音和包含 25 个音节的句子拼接起来，进行 AVQI 分析。采用 5 位有经验的评分者，使用 GRBAS 协议中的 G 级对听觉感知评估进行评分。
AVQI 评分与总体嗓音质量的听觉感知评估呈显著正相关（r=0.717，P<0.001）。AVQI 对发音障碍的嗓音有 2.98 的阈值。采用双向混合效应模型、单测量类型、绝对一致性定义的组内相关系数显示，AVQI 在土耳其语中的重测信度非常好（组内相关系数=0.986）。
AVQI v.02.06 是一种区分发音障碍和正常嗓音的有效且可靠的工具，在土耳其语中具有极好的重测信度。
