Interface for Barge-in Free Spoken Dialogue System Based on Sound Field Reproduction and Microphone Array
A barge-in free spoken dialogue interface using sound field control and microphone array is proposed. In the conventional spoken dialogue system using an acoustic echo canceller, it is indispensable to estimate a room transfer function, especially when the transfer function is changed by various interferences. However, the estimation is difficult when the user and the system speak simultaneousl...
متن کاملInterface for Barge-in Free Spoken Dialogue System Combining Adaptive Sound Field Control and Microphone Array
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...

متن کاملBARGE−IN FREE SPOKEN DIALOGUE INTERFACE USING NULLSPACE−BASED SOUND FIELD CONTROL AND BEAMFORMING (ThuAmPO4)
This paper describes a new small−scale interface for a barge−in free spoken dialogue system combining a multichannel sound field control and a microphone array, in which the response sound from the system can be canceled out at the microphone points. The conventional method inhibits the user from moving because the system forces the user to stay in the fixed position where the response sound is...
متن کاملDoctoral Dissertation Barge-in Robust Spoken Dialogue Interface Using Multichannel Sound Field Control and Array Signal Processing
A spoken dialogue system is demanded as a user-friendly human-machine interface that does not require any special skills in its manipulation. Speech has advantageous features: they are hands-free and eyes-free, i.e., one can use speech while doing other tasks. For effective utilization of the features, it is desirable that the system can be used even when the user stands away from the microphon...
