| contents | In this paper, we propose a speech enhancement method us ing dual-path Multi-Channel Linear Prediction (MCLP) filters
and multi-norm beamforming. Specifically, the MCLP part in
the proposed method is designed with dual-path filters in both
time and frequency dimensions. For the beamforming part, we
minimize the power of the microphone array output as well as
the l1 norm of the denoised signals while preserving source sig nals from the target directions. An efficient method to select the
prediction orders in the dual-path filters is also proposed, which
is robust for signals with different reverberation time (T60) val ues and can be applied to other MCLP-based methods. Eval uations demonstrate that our proposed method outperforms the
baseline methods for speech enhancement, particularly in high
reverberation scenarios. |
