Abstract: An anomaly detection apparatus comprises a pattern storage part, first long time-span feature extraction part, a pattern feature calculation part, and a score calculation part. The pattern storage part stores a signal pattern model trained based on an acoustic signal for training in a first time-span and a feature for training being calculated from signal for training in a second time-span that is longer than first time-span. The first long time-span feature extraction part extracts a long time-span feature for detection associated with the feature for training from a signal being a detection target. The pattern feature calculation part calculates a signal pattern feature related to a signal being a detection target based on the signal being a detection target, the feature for detection, and the signal pattern model. The score calculation part calculates score to detect anomaly in the signal being detection target.
