谐波重构先验信噪比估计算法
A priori SNR estimator based on harmonic regeneration
摘要
Abstract
A priori SNR estimator of single-channel speech enhancement can effectively remove the noise when the SNR is high,but the speech distortion is more serious when the SNR is low.In this paper,a priori SNR estimator using harmonic regeneration is proposed.In the algorithm,the power spectrum reprocessing(including weighting and square)can be used to process speech signals,which can enhance the periodicity of the speech signal;and then the harmonic regeneration is carried out,thus the harmonic component is enhanced.Experimental results show that the proposed algorithm can effec-tively enhance the harmonic component of the speech signal in low SNR,improve the performance of this algorithm and reduce speech distortion than a priori SNR estimator of speech enhancement.关键词
