改进相位谱补偿的语音增强算法
Speech enhancement using improved phase spectrum compensation
摘要
Abstract
The typical phase spectrum compensation method has the negative enhancement performance in a low SNR,so the improved phase spectrum compensation method is proposed for this problem.First,the algorithm compensates the speech spectrum through the phase compensation function obtained by calculating the signal to noise ratio of each frame;second,by the new speech presence probability algorithm to estimate the noise power spectral density;finally,we apply the new phase spectrum and the estimated noise in the wiener filter.Simulation results show that the improved algorithm proposed in this paper can effectively improve the ability of voice systems to remove noise especially in a low SNR.关键词
