Apple has begun beta testing its Audio Intelligence features on Apple Watch Series 12 and Ultra 4 through the watchOS 27.3 developer update. Live Rewind lets users double-press the Digital Crown for a text transcript of the last 15 seconds of nearby conversation, while Siri Recap generates optional summaries that auto-delete after seven days unless saved. Both features process audio on-device in the Secure Exclave with no permanent recordings stored. The rollout comes after the features were announced at September's Surprise and Shine event and expands Apple Intelligence deeper into wearable experiences.
