Abstract (in Japanese) (See Japanese page) 
(in English) We propose an abnormal sound detection system for surveillance microphone. The system uses models for normal sounds produced actually in surveillance place and detects sounds not learned as abnormal sounds. Therefore, the system doesn't limit detection targets to particular events and can cope with any abnormal events. The detection performance of the proposed system was examined for actual environmental sounds. The performance was improved by a multi-stage GMM that models normal sounds that rarely occur. Furthermore, we examined incorporating a dynamic variation of acoustic features by segment features.
