Abstract
This paper considers a moving sound source tracking problem and show that the direction of the moving sound source can be sequentially estimated by our frame-wise DOA (Direction of Arrival) estimation approach, which has been originally developed for a fixed sound source by using only mixed signals observed at a pair of microphones. From several simulation results, it has been confirmed that our approach can successfully track the moving sound source in a real time manner under the environments where the signal-tonoise ratio is more than 20dB and the reverberation time is within 200msec.
