Experimental results show that the new method of research can unveil the relations between acoustic features and pathological causes of hoarse speech and thus provides theoretical and experimental bases for non-contact diagnoses of laryngeal diseases and for improving the tone quality of hoarse speech. 实验表明,基于声门波和声带振动模型的嘶音研究可以揭示嘶音的声学特征参数与病理因素的关系,为实现喉科疾病无接触诊断以及嘶音音质的改善提供理论和实验依据。
Methods: We chose 40 patients with laryngeal carcinoma, and made frequency spectrum analysis of their voices with USSA computerized sonagram and frequency spectrum analysis system. We examined their speech intelligibility, and calculated Pearson correlation coefficients simultaneously. 方法:应用USSA计算机语图频谱分析系统对40例喉癌术后患者的发声进行频谱分析,同时检测语言可懂度,并计算两者间的相关系数。
