dc.description.abstract This paper describes a new interface for a barge-in free spoken dialogue system combining an adaptive sound field control and a microphone array. In order to actualize robustness against the change of transfer functions due to the various interferences, the barge-in free spoken dialogue system which uses sound field control and a microphone array has been proposed by one of the authors. However, this method cannot follow the large change of transfer functions. To solve the problem, we introduce a new adaptive sound field control that follows the change of transfer functions. The experimental results reveal that the proposed method can improve the reduction accuracy of response sound in comparison with the conventional acoustic echo canceller as well as the previously proposed method which simply uses fixed sound field control system. en
