摘要
本文根据汉语语音信号的特征,采用双通道输入的方法将采集的语音信号输入IBM-PC微机的内存中,与单通道输入方式相比,提高了高频语音信号的信噪比,增加了语音信号的动态范围,为语音分析提供了较好的预处理.
According to the traits of Chinese speech signals, this paper introduces a twochannel method for inputting speech signals into the memory of IBM-PC microcomputer. Compared with the widely used single-channel input method, the new method increases the signal-noise ratio of speech signals at high frequency and extends the effective range of speech signals.The interface circuit supplies a better preprocessing for speech analysis.
