摘要
利用函数逼近原理和主成份分析方法，提出了一种可用于解决语音信号时间规正和简化神经网络结构的语音信号主分量特征．该特征的提取过程模拟了人耳听觉系统的信息感知过程．
Using function approximation technology and principal component analysis method, this paper presents a principal component feature to solve the time alignment problem and to simplify the structure of neural network. Its extraction simulates the processing of speech information in human auditory system. The experimental results show that the principal component feature based recognition system outperforms the standard CDHMM and GMDS method in many aspects.
