摘要
An adaptive estimation method and device for a post-reverberation power spectrum in a reverberation speech signal. The adaptive estimation method for a post-reverberation power spectrum in a reverberated speech signal comprises: obtaining an estimation for a subband adaptive power spectrum of a reverberation speech signal picked up by a microphone (51); acquiring a delayed linear prediction (DLP) coefficient vector for estimating a post-reverberation subband adaptive power spectrum in the reverberation speech signal (52); and according to the subband adaptive power spectrum estimation of the reverberation speech signal and the DLP coefficient vector, obtaining a post-reverberation subband adaptive power spectrum estimation (53).
