本研究的目的是确定声学嗓音质量指数（AVQI）的重测变异性，并探讨测试的两个组成部分的权重（持续元音和连续语音）与最终AVQI评分的关系。在本研究中，43名不同程度声音嘶哑的受试者每人使用AVQI评估两次。两次AVQI重复（t = 1.205; p = 0.235）。重测程序结果值为0.54，证实AVQI评分变异性水平较低。AVQI评估的最终结果受元音/a/的持续发音的影响最大（r（2）= 0.88.）。虽然持续发声对AVQI评分的影响显著大于连续语音（z = -aEuro parts per thousand 3.34; p < 0.01），但后一个分量对最终结果也有很大贡献（r（2）= 0.55）。结合这两个语音元素显示了更大的贡献，持续元音发声的最终AVQI分数。
The aim of this study was to determine the test-retest variability of the Acoustic Voice Quality Index (AVQI) and to investigate the weighting of the test's two components (sustained vowel and continuous speech) with regards to the final AVQI score.During this study, 43 test subjects with varying degrees of hoarseness were each assessed twice using the AVQI.No statistically significant differences were found between the end results of the two AVQI repetitions (t = 1.205; p = 0.235). The test-retest procedure outcome value of 0.54 confirms a low level of AVQI score variability. The end result of the AVQI assessment is most strongly influenced by sustained phonation of the vowel /a/ (r(2) = 0.88.). Although sustained phonation has a significantly greater influence on AVQI score than continuous speech (z = -aEuro parts per thousand 3.34; p < 0.01), the latter component also makes a substantial contribution to the final result (r(2) = 0.55).The results confirm a low level of test-retest variability within the AVQI. Combining the two speech elements showed a greater contribution of sustained vowel phonation to the final AVQI score.
