Multichannel Two-Stage Beamforming with Unconstrained Beamformer and Distortion Reduction

This paper proposes a novel multichannel speech enhancement technique for reverberant rooms that is effective when noise sources are spatially stationary, such as a projector fan noise, an air-conditioner noise, and unwanted speech sources at the back of microphones. Speech enhancement performance o...
