| Abstract: | In this paper, we propose a DOA (Direction Of Arrival) estimation method of speech signal for both azimuth and elevation directions. Our previous DOA estimation method achieves high precision and uniform spatial resolution by integrating the frequency array data[1] generated from microphone pairs in an equilateral-triangular microphone array[2]. In the method presented here, we extend the method using four microphones located at the apices of regular tetrahedron to enable the method to estimate the elevation angle from the array plane as well. Furthermore, we introduce an idea for separate estimation of azimuth and elevation to reduce the computational loads. | ||
