Speech enhancement performance significantly degrades when the analog-to-digital converters of the different microphones sample at different sampling rates. In this paper, Speech enhancement method is proposed using amplitude-spectrum beamformer for an asynchronous distributed microphone array. This proposing method is based on the speech sparseness on the amplitude-spectrum plane. Several experimental results in an actual environment are shown to confirm a performance of the proposed method. |
