Abstract In order to improve the performance of speech communication system in noisy environment, a dual micro-array speech enhancement method based on subband spectrum subtraction and generalized sidelobe canceller is proposed. Based on dual micro-array structure and the subband structure analysis, this method suppresses the noise in the low frequency band by the spectrum subtraction method which may employ variable over-subtraction factor in it and suppresses the non-coherent noise part in the high frequency band by modifying cross power spectrum subtraction method, respectively. Then generalized sidelobe canceller and voice activity detector are combined with the method mentioned above to further suppress the influence of strong coherent noise further. The experimental results show that the proposed method can suppress the influence of noise and improve the intelligibility of speech more effectively.
