The goal was to identify acoustic and aerodynamic indices that allow the discrimination of a benign organic dysphonic voice from a normal voice. Fifty-three patients affected by dysphonia caused by vocal folds benign lesions, and a control group were subjected to maximum phonation time (MPT) measurements, GRB perceptual evaluations and acoustic/aerodynamic tests. All analyzed variables except the airflow variation coefficient were significantly different between the two groups. The unique significant factors in the discrimination between healthy and dysphonic subjects were the aerodynamic indices of MPT and Glottal efficiency index, and the acoustic index Shimmer. These results show that a combination of three parameters can discriminate a voice deviance and highlight the importance of a multidimensional assessment for objective voice evaluation.
目标是识别能够区分良性器质性发声障碍嗓音与正常嗓音的声学和空气动力学指标。53名因声带良性病变导致发声障碍的患者以及一个对照组接受了最长发声时间（MPT）测量、GRB感知评估和声学/空气动力学测试。两组之间除气流变化系数外的所有分析变量均存在显著差异。在区分健康受试者和发声障碍受试者时，唯一显著的因素是MPT的空气动力学指标、声门效率指数和声学指标闪烁度。这些结果表明，三个参数的组合可以区分嗓音异常，并突出了多维评估在客观嗓音评估中的重要性。
