探讨基于嗓音声学分析来检测声带息肉病变的一种新的方法。将持续稳定的元音为研究对象,以人体声带的振动和发声原理为基础,将声带的振动简化为一般的理想自由弦振模型,通过波动方程的解和单侧声带息肉病变的物理特征来推导其病变后的声学信号特征,利用声带对称性和耦合性建立内禀特性来检测声带的息肉病变,并给出了其频域的分析方法。

This article mainly proposed a new method of detecting vocal polyp through the analysis of vowels.Based on the principle of the vibration,the vocal cord was simplified into a free string.According to the physical feature of vocal polyp and the resolution of wave equation,the character of unilateral polyp was deduced in the spectrum domain of the signal.An intrinsic property was set up to detect this lesion because of the symmetry and coupling function of the vocal fold.At last,it raised the way in the spectrum domain.
