Abstract: In this paper, the authors proposed an efficiency estimation coherence noise method for distributed microphones. It utilizes an estimation of speech presence probability for calculating coherence noise, and signal-to-noise ration. Based-Wiener filter a gain function, which derived from the achieved signal-to-noise ratio, has proven the effectiveness of suppressing background noise while save the target speech. The proposed algorithm is useful for two-channel speech enhancement systems with microphone constellations where the microphones are placed separately, and can be combined with coherence based two-microphone noise reduction systems.
