Abstract :
In this paper, a novel speech enhancement algorithm is proposed. The algorithm controls the amount of noise reduction according to information about speech absence or presence. Compared to conventional linearly constraint minimum variance beamforming, the proposed noise reduction achieved remarkable improvement in speech recognition rates.
