N2 - The weighted-prediction-error (WPE) method, which uses variance-normalized multichannel delayed linear prediction to suppress the late reverberation component, is one of the most effective algorithms for speech dereverberation. The prediction-error filter in WPE, however, has to be long enough to estimate accurately the late reverberation component, which results in a high computational complexity. To deal with this issue, this paper proposes to use Kronecker product to decompose the high-dimensional multichannel linear prediction-error filter into three groups of low-dimensional filters. This scheme not only leads to effective dereverberation performance, but also reduces the computational load, which is very conducive to real-time speech systems.
