A Novel Speech Enhancement System Based on the Coherence-Based Algorithm and the Differential Beamforming

2018 IEICE transactions on information and systems  
This letter proposes a novel speech enhancement system based on the 'L' shaped triple-microphone. The modified coherence-based algorithm and the first-order differential beamforming are combined to filter the spatial distributed noise. The experimental results reveal that the proposed algorithm achieves significant performance in spatial filtering under different noise scenarios. key words: speech enhancement, coherence-based algorithm, differential beamforming, spatial filtering
