| Abstract(in English) | In this paper, we study on a multiple sound source localization method using two microphones. In speech signals, there are several time-frequency regions denominated by the single source energy because of the speech sparseness and frequency energy localization characteristic even if multiple sound sources exist simultaneously. In such regions, we can carry out the sound source localization using two microphones. In the method, we prevent a accuracy degradation by the PAST-IPLS. In addition, we adjust a forgetting factor value used in the PAST depending on a variation of evaluation function value. Several experimental results in actual room environments are shown to present the effectiveness of proposed method. |
