- 建立一个简单的语音信号加噪去噪系统。先录入语音，进行频谱分析，再分别对加噪语音信号和去噪之后的信号进行频谱分析。(A simple speech signal denoising system is proposed. First input the speech, carry on the frequency spectrum analysis, and then carry on the frequency spectrum analysis to the noisy speech sign
语音信号处理
- 对一段语音信号进行读入，并加入高斯白噪声，输出原始信号和噪声信号的频谱，进行分析比较，最后去掉噪声，再对频谱进行分析。(Read a section of the voice signal, and add the Gaussian white noise, the output of the original signal and noise signal spectrum, the analysis and comparison, and finally remove the noise,
对语音进行加噪、去噪、变速等处理
- 基于matlab对语音信号进行加入随机噪声、去噪滤波、变声变速等处理，并显示出相关波形和频谱图。(Based on matlab, the speech signal is processed by adding random noise, denoising and filtering, changing sound and speed, and the relevant waveforms and spectrum diagrams are displayed.)
