Abstract(in English) Along with the progress of super aged society, the number of elderlies living alone has increased. Therefore, the demand for services to watch the daily life of the elderly is increasing. Instead, video cameras and pendant sensors have problems such as privacy infringement and annoyance to wear things. Therefore, the authors have proposed a watching system that detects abnormal life sounds using a neural network. However, it is extremely difficult to collect all the abnormal life sounds for learning. Therefore, if the input sound has been learned in advance or not, and if an unlearned sound (unlearned sound) is detected, the user is designated as normal and normal. By adding the sound to the learning sound, the learning sound is expanded, and if there is no input that it is normal, a system that judges that it is abnormal is examined. Ten models with different initial weight values were prepared, and the experiment showed that the standard deviation of the output values differed between learned and unlearned. As a result of experiments, the performance improved compared to the conventional method. In this study, we use the public data set ToyADMOS to detect abnormal sounds and unlearned sounds.
