摘要
通过阐述线性预测的基本原理，针对语音信号的频谱特性，提出了一种改进的LPC方案。该方案可以提高频谱特性，降低预测阶数，提高预测计算的速度，易于在计算机上实现。
The Linear Predictive (LPC) is one of the important methods in speech processing. In this paper we first discuss the fundamental principles of LPC. Based on the characteristics of the speech spectrum, an improved LPC scheme is presented. The scheme can improve the characteristics of the spectrum, diminish the predictive bank number and accelerate the speed of processing. Especially, it can be realized by computers.
