摘要
Abstract
The trade-off among amount of noise reduction, the level of musical residual noise and the speech distortion in high noise environment has to be solved. This study focuses on noise estimation to boost the performance of speech enhancement algorithms by combining statistical estimators of the spectral magnitude of the speech and noise. The noise spectral magnitude estimator is derived from the speech magnitude estimator, with which a modified a priori SNR estimation is given. The simulated experiments indicate that significant improvement could be achieved. For the speech enhancement, the algorithm obtains an ob-vious improvement in reducing speech distortion, with little musical noise retained.关键词
