要約(英語): For realizing useful speech interface, pre-processing such as speech enhancement and sound source localization must be finished in real-time. In the research into sound source localization, various methods with microphone-array have already been developed, and these methods localize a sound source based on spatial scanning by fixed resolution in each frequency. Therefore, elapsed time is increased, and real-time processing is difficult with higher spatial resolution. To overcome this problem, we proposed the localization method based on multi-resolution scanning in spatial and frequency domains. The results of evaluation experiments indicated that the proposed method could realize a real-time processing without degrading the localization accuracy.
