Abstract
An abnormal sound identification device includes an arithmetic device and an output device. The arithmetic device is configured to identify frequency-time data recorded in a vehicle, specify a first time range and a second time range in the frequency-time data, input the frequency-time data to the trained model to cause the trained model to identify an abnormal sound generated in the first time range as a first abnormal sound based on the input frequency-time data and cause the trained model to identify an abnormal sound generated in the second time range as a second abnormal sound, and cause the output device to output a kind of the first abnormal sound with the kind not matching a kind of the second abnormal sound among the first abnormal sounds.
