| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We study sound source localization in near field. In the research into sound source localization, 2D-MUSIC has already been developed. However, problematically its performance degrades in diffused noisy environments. The localization method based on CSP in near field has already been developed too. However, the accuracy of licalization depends on the one of estimation for time delay between paired microphone. To overcome these problems, we have proposed 2D-CSP with multiple channel microphones for robustly localization. We carried out the evaluation experiments in a conference room. From experimental results, we confirmed that the proposed method can more robustly localize a sound source than conventional methods. | |
