帧间自适应的压缩感知谱减去噪方法
Speech denoising method based on adaptive inter-frame compressed sensing of spectrum subtraction
摘要
Abstract
Since the noisy speech denoising based on compressed sensing theory has low signal-to-noise ratio,and the spectrum subtraction used to denoise the noisy speech still has poor speech signal,a speech denoising method based on adap-tive inter-frame compressed sensing of spectrum subtraction is put forward. The traditional compressed sensing theory can't realize the adaptive inter-frame denoising effect while reconstructing the speech signal,so an improved algorithm is proposed,and ap-plied to the denoising process of the spectrum subtraction. The experimental results show that,in comparison with the classical spectrum subtraction,the proposed algorithm used to denoise the noisy speech can improve the denoising effect of the noisy speech,and effectively eliminate the background noise and music noise that the spectrum subtraction can't do.关键词
