摘要
针对基本谱减算法中关于噪声是零均值的高斯分布的假设,提出了一种改进谱减算法,从而打破了这个假设。实验表明这种改进谱减算法有效地提高了增强效果,更好地抑制了音乐噪声。
In this paper,a new spectral subtraction method is presented,which breaks the assumption that the noise is Gaussian distribution with mean 0 in the original spectral subtraction method.Experimental results show that this proposed method effectively improves the speech quality and reduces the musical noise.
