| Abstract(in English) | In this contribution, we propose a DOA (Direction Of Arrival) estimation method of speech signal whose angular resolution is almost uniform with respect to DOA. Our previous DOA estimation method [1] achieves high precision with only two microphones, however its resolution degrades as the propagating direction apart from the array broadside and it cannot discriminate whether the speaker is located in front or behind. In the proposed method, the microphones are located at vertices of equilateral-triangle, and the integration of the array data given by three pairs of microphones is applied. The efficiency of the proposed method is shown both from the simulation and experimental results. |
