Because that processing happens on the watch, the sound alerts can work even when an iPhone is not nearby. The feature is intended in part to help people who may otherwise miss important environmental sounds, including users with hearing loss.
Live Rewind takes the idea further by allowing users to retrieve something they just heard. Double-tapping the Digital Crown can generate a transcript of the previous 15 seconds of speech.
That transcript can then be used with Siri or saved in the Siri app for later reference. Apple has suggested the feature could help when someone misses part of a conversation or wants to remember information that was just shared.
Siri Recap is designed for longer interactions. The optional feature uses ambient audio processing to create high-level notes from conversations, then uses Apple Intelligence to generate a title, summary and key points.
Apple says Siri Recap can be enabled only during selected periods rather than running continuously. Users can also turn it off entirely.
The new capabilities raise privacy questions because they allow an Apple Watch to process conversations taking place around the wearer. Apple says the system does not create or retain audio recordings, and the raw audio cannot be accessed by Apple.
Live Rewind transcripts and Siri Recap content saved in the Siri app are also protected with end-to-end encryption. Apple says the system does not identify or assign speech to individual speakers.
Live Rewind also provides visible and audible cues when it is activated. According to Apple, the watch displays a full-screen microphone animation and plays a chime when the feature is used. The distinction between the three features is significant. Sound detection is focused on environmental awareness, while Live Rewind gives users a short retrospective transcript and Siri Recap produces broader AI-generated notes from conversations.
Siri Recap remains optional and can be scheduled for particular times of day. That gives users control over when ambient listening is active rather than making it a permanent default.
Live Rewind and Siri Recap depend on Siri AI, which Apple says will become available in beta later this year starting in English. Additional languages are expected afterward.
