voiced speech

基本解释

Voiced speech is interpreted as a concatenation of slowly evolving pitch cycle waveforms.
濁音語音可以看作是慢變化的基音周期波形的連接。
Firstly we analyze the speech with reversed polarity and present the idea of post-filtering of the LPC residual of these voiced speech frames.
該算法重點研究經典LPC分析後基音激勵方曏曏下的語音，對這種濁音LPC殘差進行後濾波以取代預增強的方法使其逼近語音激勵。
Based on the feature of smoothly varying pitch period and the quasi-periodic structure of voiced speech, an algorithm for pitch prediction is presented.
根據基音周期平滑變化的特點，基於語音信號的準周期性進行了語音信號的基音提取。
