A Dual-Microphone Speech Enhancement Algorithm Based on the Coherence Function

  title={A Dual-Microphone Speech Enhancement Algorithm Based on the Coherence Function},
  author={Nima Yousefian and Philipos C. Loizou},
  journal={IEEE Transactions on Audio, Speech, and Language Processing},
A novel dual-microphone speech enhancement technique is proposed in the present paper. The technique utilizes the coherence between the target and noise signals as a criterion for noise reduction and can be generally applied to arrays with closely spaced microphones, where noise captured by the sensors is highly correlated. The proposed algorithm is simple to implement and requires no estimation of noise statistics. In addition, it offers the capability of coping with multiple interfering… CONTINUE READING
