内容記述 | We present a multichannel speech enhancement method based on MAP speech spectral magnitude estimation using a generalized gamma model of speech prior distribution, where the model parameters are adapted from actual noisy speech in a frame-by-frame manner. The utilization of a more general prior distribution with its online adaptive estimation is shown to be effective for speeech spectral estimation in noisy environments. We tested the proposed algorithm in an in-car speech database and this significantly improved the speech recognition performance, particularly under nonstationary noise conditions such as music, air-conditioner and open window. | |||||
