| Abstract(in English) | Studies on the direction of arrival estimation of sound sources using a microphone array have been interested. In real circumstances relative locations between sensors and sources are not always stationary. This study proposes the method to track moving sources based on a recently developed method employing the time-frequency analysis. Specific feature of the moving sources problem is to obtain accurate estimate utilizing the observation within a short time interval, thus stable estimation will be difficult. A particle filter approach with introduced particle groups corresponding individual sources is proposed in this study which enables to track the moving sound source by using short period of time-frequency data. The method alters the number of particle groups dynamically and it can track multiple sources direction simultaneously. Through the conducted experiments, the method was proved to be effective even for real environments. |
