1·This investigation was designed to approach a novel estimation method of glottal vocal efficiency(GVE) based on conversion function of voice source.
在澄清嗓音源概念的基础上提出了一种以嗓音源变换函数为基础的声门发声效率估计方法。
2·On the base of LF-4 derivative glottal flow, an improved algorithm of LF-4 derivative model is proposed to synthesize voice source.
在LF - 4微分声门波模型的基础上，提出了一种LF - 4模型的改进算法，进行嗓音源的合成。
3·Vowels have something to do with glottal closure, therefore influence acoustical measures.
结论：元音不同，声门闭合度存在差异，进而影响声学测试的参数。
4·Based on the speech produce model, we find the reason of periodicity disappearance and the extremum number increase by analysing the character of speech signal when the glottal closes.
于是从语音产生模型入手，详细的分析了声门闭合时刻语音信号的性质，找到了浊音信号经过小波变换后周期性消失、极值点个数增多的原因。
