Of this study was to validate the Acoustic Voice Quality Index (AVQI) in Russian language and determine threshold values to differentiate normal and dysphonic voices in russophone population.
41 recordings of patients with laryngeal hemiplegia and hemiparesis appeared after thyroid carcinomas' surgical treatment and laryngeal cancer from the Tomsk Cancer Research Institute were used, as well as 10 new recordings of normophonic people, composing a control group. Voice samples included the first quatrain of the poem «Sail» written by M.Yu. Lermontov, and sustained vowel «a». Four specialists who work with voice disorders (three speech-language pathologists and one phoniatrist) rated degree of dysphonia for all voice sample. Moreover, the AVQI was calculated for each sample.
There was a statistically significant correlation between auditory-perceptual assessment and the AVQI (=0.74), this confirms that AVQI is effective in evaluating voice disorders. The group of people with normal voice had relatively low values of AVQI, whereas the group of patients with laryngeal diseases had relatively high values. Analysis of ROC-curve showed that AVQI has excellent diagnostic accuracy to differentiate normal and dysphonic voices (AUC=0.966).
The AVQI is the excellent tool for objective assessment of voice disorders in the Russian population/.
本研究的目的是验证俄语版的嗓音声学质量指数（AVQI），并确定俄语人群中区分正常嗓音和嗓音障碍的阈值。
使用了托木斯克癌症研究所41份甲状腺癌手术治疗后出现喉偏瘫和偏瘫患者以及喉癌患者的录音，以及10份正常嗓音者的新录音，组成对照组。嗓音样本包括M.Yu.莱蒙托夫所写诗歌《帆》的第一节四行诗，以及持续元音“a”。四名从事嗓音障碍工作的专家（三名言语治疗师和一名耳鼻喉科医生）对所有嗓音样本的嗓音障碍程度进行评分。此外，计算每个样本的AVQI。
听觉感知评估与AVQI之间存在统计学显著相关性（=0.74），这证实AVQI在评估嗓音障碍方面是有效的。正常嗓音人群的AVQI值相对较低，而喉部疾病患者组的值相对较高。ROC曲线分析表明，AVQI在区分正常嗓音和嗓音障碍方面具有出色的诊断准确性（AUC=0.966）。
AVQI是客观评估俄罗斯人群嗓音障碍的优秀工具。
