We analysed the vocal fold vibrations of 22 pathological larynges using a computer-assisted high-speed digital imaging technique. The parameters observed included symmetry, regularity, phase difference, glottal closure, amplitude, mucosal wave and periodicity difference. Voice quality was evaluated by a GRBAS system, and we examined the relation between vocal fold vibration patterns and voice quality. The intraexaminer correlation coefficient was high for the G, R and B scales. Vibratory patterns were classified according to the location of the lesion, severity of the disease, expiratory pressure and laryngeal modulation. Although there were no matches between a vocal fold vibratory pattern for one psychoacoustic impression of hoarseness, the characteristic vibratory patterns of these cases of R > or = 2.5 or diplophonia exhibited irregular glottal closure and periodicity differences. The characteristic vibratory pattern of vocal fry is a double or triple opening/closing phase, followed by a long closed phase.
我们使用计算机辅助高速数字成像技术分析了22个病理性喉部的声带振动情况。观察的参数包括对称性、规律性、相位差、声门闭合、振幅、黏膜波和周期性差异。采用GRBAS系统评估嗓音质量，我们研究了声带振动模式与嗓音质量之间的关系。检查者内相关系数在G、R和B量表上较高。振动模式根据病变位置、疾病严重程度、呼气压力和喉部调节进行分类。虽然一种心理声学上的嘶哑印象的声带振动模式之间没有匹配情况，但这些R≥2.5或双声的病例的特征性振动模式表现出声门闭合不规则和周期性差异。发声粗糙的特征性振动模式是双相或三相的开闭阶段，随后是一个较长的闭合阶段。
