Apple introduced Audio Intelligence features on the Apple Watch Ultra 4 and Apple Watch Series 12, including Live Rewind, Siri Recap, and Sound Recognition. These features are designed to help users stay present and engaged throughout the day, with on-device processing for certain functions.
Live Rewind lets users review the previous moments of a conversation, up to 15 seconds, by double-pressing the Digital Crown and viewing a text snippet of the dialogue. Siri can be asked about the transcript or the content can be saved for later review.
Siri Recap offers high-level summaries of conversations after they occur, generating a title and key points in the new Siri app when enabled. A related Sound Recognition feature can alert users who are deaf or hard of hearing to important sounds such as sirens, alarms, doorbells, or a baby crying.
- Live Rewind: previous 15 seconds of a conversation
- Siri Recap: automatic summaries of conversations
- Sound Recognition: on-device alerts for important sounds
- Shazam integration: instant music title and artist display
