线性预测技术作为一种基于全极点模型假定和均方预测误差最小准则下的波形逼近
技术。本文简要介绍了LPC 技术的基本原理，并利用MATLAB 这一有力工具对语音信号进行了LPC 分析，并对阶数的选取做了比较分析。
关键词：语音信号 LPC MATLAB 仿真
Abstract：The LPC(linear prediction coding) analysis is a theory based on the all-pole model assumption and minimum mean square rule to approach a waveform, therefore, it is independent of the assumption of the speech production model. It is utilized in many field like speech waveform coding. This paper introduces the principle of the PLC analysis and chooses the proper of with MATLAB.
Keywords: speech signal processing LPC MATLAB simulation
