摘要
线性预测编码(LPC)技术是一种重要的语音信号处理技术,广泛地应用在估计基本的语音参数等方面.详细介绍了线性预测编码技术的原理以及三种基本实现算法,并着重研究了LPC技术在G.729语音编码标准中的应用,最后采用仿真工具MATLAB对语音信号进行LPC分析,验证了LPC是对语音信号谱进行估计的一种有效方法.
The linear predictive coding technology （LPC） is a kind of important voice signal processing technology. It is widely used in the fields of estimating voice signal parameters. The theory of linear predictive coding technology and three kinds of basic implementation algorithms are introduced in this paper. The application of LPC in G. 729 is studied mainly. Finally, the voice signal spectrum is analyzed using MATLAB. The experiments show that LPC is an effective way for estimating speech signal spectrum.
