Abstract
This paper proposes a method for separating the mixture of moving sound sources. When sources move, mixing matrix varies and its variation is dependent on the delay from a source to microphones. When the variation of the deley is large, it is hard to solve blind separation of moving sources. Therefore, in order to eliminate the delay between microphones, directional microphones are used and they are placed at the same point toward different directions. As a result of experiments in the real environment, the proposed method could lessen the drop of the performance which was caused by the movement of sources.
