| 摘要: |
| 本文主要阐述了语音线性预测编码中描述声道特性的全极点预测滤波器的几种激励方式,即残余信号激励,多脉冲激励及音调激励的原理和有关性能。对基带提取—高频再生残余信号的激励方式亦作了相应的介绍。 |

| Abstract: |
| The fundamental theories and properties of several excitation methods for all pole linear predietive vocal tract models such as residual excitation, multipulse excitation and pitch excitation are discussed. The excitation method which residual signal produced from baseband extraction and high frequency, reproduction is introduced. |
