1）选择一个语音信号作为分析对象，或录制一段语音信号； 2）对语音信号进行采样，画出采样前后语音信号的时域波形和频谱图； 3）利用MATLAB中的随机函数产生噪声加入到语音信号中，使语音信号被污染，然后进行频谱分析； 4）设计用于处理该语音信号的数字滤波器，给出滤波器的性能指标，画出滤波器的频率响应； 5）对被噪声污染的语音信号进行滤波，画出滤波前后信号的时域波形和频谱，并对滤波前后的信号进行比较和分析； 6）回放各步骤的语音信号，给出相应处理程序及运行结果分析。(1) Select a voice signal as an analysis object, or record a voice signal 2) sampling the voice signal, draw the waveform and frequency spectrum of the time domain before and after sampling the speech signal 3) using the random function in MATLAB generated noise was added to the speech signal, the speech signal to be contaminated, and then spectrum analysis 4) for processing the speech signal, the digital filter design, given the performance of the filter to draw the filter' s frequency response 5) on the noise pollution of the speech signal is filtered, time-domain waveform and spectrum draw before and after filtering the signal before and after filtering, and the signal for comparison and analysis 6) playback of the speech signal for each step, given the results of the corresponding processing procedures and run analysis.)
