voiced speech

基本解释

Voiced speech is interpreted as a concatenation of slowly evolving pitch cycle waveforms.
浊音语音可以看作是慢变化的基音周期波形的连接。
Firstly we analyze the speech with reversed polarity and present the idea of post-filtering of the LPC residual of these voiced speech frames.
该算法重点研究经典LPC分析后基音激励方向向下的语音，对这种浊音LPC残差进行后滤波以取代预增强的方法使其逼近语音激励。
Based on the feature of smoothly varying pitch period and the quasi-periodic structure of voiced speech, an algorithm for pitch prediction is presented.
根据基音周期平滑变化的特点，基于语音信号的准周期性进行了语音信号的基音提取。
