Abstract (in Japanese) (See Japanese page) 
(in English) It has recently been shown that the maximum likelihood estimation
approach with a time-varying source model is very effective in
achieving speech dereverberation based only on a short observation. In
addition, STFT domain processing has been shown to be promising for
implementing this dereverberation approach in a computationally
efficient way. This paper presents a way of further improving the STFT
domain speech dereverberation in terms of both computational cost and
accuracy. One important issue here is how to calculate time-domain
convolution with a long filter precisely using STFT. We introduce an
STFT domain filtering method with crossband effect compensation for
this purpose. Experimental results show that the proposed method
allows us to implement the dereverberation algorithm in the STFT domain
more precisely with less computational cost than the existing method.
