本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)
