A Speech denoising method Based on wavelet threshold and improved spectral subtraction

摘要：

　　In the speech de-noising method,wavelet threshold method and the spectral subtraction with simple algorithm and good performance has attracted the attention of many researchers.Based on the traditional spectral subtraction,the author found that the speech signal non-stationary noise cannot be effectively restrained,therefore,the improved algorithm based on wavelet threshold value and improved spectral subtraction is proposed The Experimental results show that this method in low signal-to-noise ratio,can effectively restrain music noise,enhance the signal to noise ratio (SNR) and improve the quality of speech.
