| Abstract(in English) | We propose an "unusual sound detection system" which can automatically detect unusual sounds and send hazardous situations to guards, monitoring sound environments with microphone arrays which have a lot of microphones. The objective of the system is to automatically detect unusual sounds and their directions, based on usual measurement results. If the detected unusual sound is regarded as abnormal information, our proposed system provides security and safety by sending the information to guards who watching public spaces. Differently from the conventional systems, the attractive property of the system is that the unusual sound and its direction can be detected without defining them in advance. Therefore we do not have such troublesomeness of the conventional methods that the features of the predefined unusual sounds must be modeled and training data corresponding to them must be collected. Moreover, unlike conventional systems using video cameras, our system is not limited by video camera angles. Experimental results show the validity of the proposed system. |
