Abstract—The linear predictive (LPC) is one of the most important methods in speech processing. Through the LPC spectrum, the
LPCC spectrum analysis, and unifies the LPC examination method to judge the Pitch Period. We may carry on the programming
realization using Matlab, has the realization to be simple, effect good characteristic.

摘要--线性预测（LPC）是语音信号处理中最有效的分析方法之一，通过LPC谱，LPCC谱的分析，并结合LPC检测方法判断出语音的
基音周期或共振峰。我们可以利用Matlab来进行编程实现，具有实现简单，效果良好的特点。
