摘　　要：目的探究嗓音质量指数(acoustic voice quality index,AVQI)在汉语普通话人群中的效度,能否区分正常与异常嗓音以及能否区分主观听觉感知的嗓音障碍严重程度。方法纳入59例正常嗓音者及217例异常嗓音受试者,采集持续元音/a/和汉语连续言语样本,用Praat软件计算AVQI(v02.06),5名评分者进行GRBAS评分中的G评分,取其平均值Gmean,计算两者spearman相关系数,以Gmean=0.2作为异常嗓音的临界值,绘制ROC曲线,评估AVQI区分正常与异常嗓音以及不同严重程度嗓音障碍的诊断价值。结果AVQI与Gmean的相关系数r=0.756(P<0.001)。区分正常与异常嗓音时,以Gmean=0.2作为临界值,AUC=0.849,临界值2.905;以临床诊断作为区分标准,AUC=0.788,临界值为3.18。区分嗓音障碍严重程度时,正常vs轻度异常AUC=0.770,临界值为1.985;轻度异常vs中度异常AUC=0.755,临界值为4.17;中度异常vs重度异常AUC=0.799,临界值为6.36。结论AVQI是一种评估汉语普通话人群嗓音总体情况的快速、简便的工具,能够有效区分正常嗓音及异常嗓音,并能在一定程度上区分异常嗓音严重程度。Objective To study the validity of acoustic voice quality index(AVQI)in Mandarin Chinese language,to investigate the accuracy of AVQI in discriminating normal and dysphonic voice,and the accuracy in discriminating across the perceptual categories of dysphonia severity.Methods This study included 59 subjects with normal voice and 217 subjects with dysphonic.Voice samples of sustained vowel/a/and continuous speech were collected.AVQI was calculated using AVQI(v02.06)script in Praat software.G score of GRBAS system was assessed by 5 raters and the mean value was used in following analysis.Spearman correlation coefficient was calculated.ROC curves were drawn to evaluate the accuracy of discriminating normal and dysphonic voice,and discriminating across the perceptual categories of dysphonia severity.Results The correlation coefficient of AVQI and Gmean was 0.756(P<0.001).When discriminating normal and dysphonic voice at Gmean=0.2,AUC=0.849 and threshold was 2.905.When discriminating them under clinical diagnosis,AUC was 0.788 and threshold was 3.18.When discriminating voice of different severity,AUC and threshold of normal vs slight were 0.770 and 1.985 respectively.Those of slight vs moderate were 0.755 and 4.17,and those of moderate vs severe were 0.799 and 6.36 respectively.Conclusion The AVQI is an easy-to-use and quick tool for the objective measure of overall voice quality in Mandarin Chinese language.It could discriminate normal and dysphonic voice,and the voice with different dysphonia severity to a certain extent.
