Speaker direction tracking using microphones located at the vertices of equilateral-triangle

In this paper, we propose an algorithm of speaker direction tracking using three microphones located at the vertices of an equilateral triangle. The method estimates the speaker direction by integrating the data derived from three different microphone pairs to achieve the omnidirectionality of accuracy. Using the algorithm, we propose a tracking method of speaker direction. At the end of this report, we show some results of simulation and real experiments to verify the effectiveness of the proposed method.
