摘要
语音信号的线性预测分析是语音信号处理中的重要部分,线性预测系数提取的速度和精确程度直接影响后续的处理工作.现提出一种基于BP神经网络的线性预测系数的求解方法.实验表明,该方法能以较少的训练次数得到较高的计算精度.
The LPC analysis is an important part of speech signal process. The speed and precision of the LPC coefficients calculation can influence the later processing. In this paper, a method of the calculation of LPC coefficients is proposed by use of BP neural network. Experimental results show that this method effectively improves the calculation precision with less training time.
