Adaptive real-time estimation of speech LPC coefficients by LMS algorithm

本文提出了一种应用LMS自适应算法对语音LPC参数进行实时提取的方法,分析了这种算法在语音环境下的收敛性及实现实时处理的条件。本文还对残差序列的实时提取进行了讨论。文中对于有关的理论进行了计算机模拟验证,并对比传统的经典方法得出了比较理想的实验结果。

In this paper, we propose a method to extract speech LPC coefficient by using LMS adaptive algorithm, and have analyzed the convergence of this algorithm used to speech signal and conditions of real-time processing. Method of extracting the real-time residual sequence has also been studied. The operation of this method has been modelled by the computer and the experimental results have been proved to be better than the typical autocorrelation method.
