Abstract (in Japanese) (See Japanese page) 
(in English) We have developed a system of monitoring safety for preschoolers and senior citizens who cannot tell accurately about their own experiences and condition. A wearable device which has the recording capability attached to preschoolers and senior citizens, and their family can check the device wearer’s voice recorded by the device. When the wearer’s voice is recorded, conversation around the wearer might be input unintentionally. The privacy of the person who was inadvertently recorded may be violated. Therefore, this system provides the family with only the wearer’s voices in the recorded data. Previously, there have been studies about recognizing voices, we must record in a particular condition. In this system, it is possible to detect the wearer`s voices without constrained conditions because the wearable device has a differential microphone that can tone down ambient sounds, and the microphone can emphasize the wearer’s voice more than the ambient sounds. Furthermore, it is possible to detect the wearer’s voices in facilities (e.g. nursery school) and send detected voices to their homes by constructing the wearable device that has a microcomputer and a wireless LAN module. In the evaluation experiment, this system can effectively tone down ambient sounds.
