Microphone array speech enhancement based on a generalized post-filter and a novel perceptual filter

摘要：

The theoretic foundation of traditional microphone array post-filters is the assumption that the noise between sensors is uncorrelated.However,this assumption is inaccurate in real environments since the correlated noise exists.In this paper,a generalized microphone array post-filter is proposed to deal with both the correlated and uncorrelated noise in environments and a novel perceptual filter is proposed to reduce the musical residual noise introduced by the post-filter.Experiments show that the proposed technique produces impressive results in terms of quality measures of the enhanced speech.
