Apple Sound Recognition

Sound Recognition is an accessibility feature on Apple iPhone and iPad, introduced in iOS 14 in 2020, that listens for selected sounds using on-device processing and shows a notification when one is detected. Detectable sounds include fire, smoke and siren alarms, doorbells, door knocks, a baby crying, appliances, car horns and animals, and users can train custom alarm and appliance sounds.
