People who are hard of hearing have difficulty hearing life sounds necessary to live indoors. Therefore, various products are available to support them. Nevertheless, these devices are insufficient in terms of convenience and cost. For those reasons, we propose a system that identifies sounds related to daily life activities. We have developed the system as a software application for use with a mobile terminal such as a smartphone. We conducted an evaluative experiment to verify its identification performance. Results confirmed that it can identify life sounds of ten types with high accuracy: over 90%. As described herein, we also present results of the performance evaluation experiment of the developed system. Additionally, we discuss challenges for development of the current system from a practical perspective.
