| Abstract(in English) | Based on the sparsity of sounds, this paper proposes a frame-wise DOA (direction of arrival) estimation of a target sound source in the direction of the range of ± 30° from the front of two microphones: First, the mixtures observed at the microphones are transformed at each frame to complex spectra by short-time discrete Fourier transform. Then, based on their phase difference, local DOAs are calculated for obtaining a distribution of these DOAs at each frame. Next, the distribution is evaluated by a sparsity measure and, the frame with the evaluate value over a certain threshold is judged as a single-source frame. Finally, for the distribution, its peak is searched and the angle taking the peak value is adopted as the DOA estimate. Several experiments were carried out to verify our proposed DOA estimation. It has been found that the proposed estimation is valid for the true DOA being -30° to 30° under the condition where SNR≧ 20[dB] and RT_<60>≦= 200[msec]. |
