Objectives. The aim of the present study was to investigate the validity (both concurrent and diag-nostic) and test-retest reliability of Acoustic Voice Quality Index (AVQI) version 2 (AVQI 02.06) in Turkish speaking population.Materials and Methods. 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 bal-anced 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 analy-sis was conducted. The auditory-perceptual evaluation was performed by five experienced raters with Grade (G) from GRBAS Protocol.Results. There was a statistically significant correlation between AVQI scores and auditory-perceptual evalua-tion of overall voice quality (rs = 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 correla-tion coefficient = 0.986).Conclusion. 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.
