Abstract(in English) This paper describes a new interface for a barge-in free spoken dialogue system combined an adaptive sound field control and a microphone array. It is essential for an acoustic echo canceller to estimate transfer functions and update the adaptive filter coefficient, especially in the case of the change of transfer functions due to the various interferences. In addition, the estimation process of transfer functions prevents a user from uttering freely and simultaneously during the response of a dialogue system. In order to actualize the robustness against the change of transfer functions, the barge-in free spoken dialogue system which using sound field control and a microphone array has been proposed. However, this method cannot follow the 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 reduction accuracy of response sound is improved in comparison with the MOMNI method.
