基于MATLAB的语音信号去噪方法应用

以MATLAB为平台,利用滤波器去噪方法对含噪声的语音信号进行去噪处理,并从频域角度利用IIR和FIR两种滤波器去噪方法进行去噪,并对结果进行了对比分析,为加强程序的友好性和可视性,采用GUI编程的方法设计了语音信号去噪系统用户界面。实验结果证明,该方法能够实现对夹杂噪声的语音信号进行有效提取,有助于在噪声下提取微弱信号的研究。...

The noise in speech signal was removed by methods of [IR and FIR in the domain perspective with Matlab. The results of tile denoising by the two methods were compared. To improve the friendliness and visuality, a denoising system user interface was designed by GUI program. It was found that this method effective in extracting speech signal with noise.
