watchOS 27.3 beta adds Apple’s always-on Audio Intelligence features

Apple’s new watchOS 27.3 developer beta introduces Audio Intelligence features that let Siri use the Apple Watch’s microphone while the watch is listening. The rollout includes Siri Recap, which uses ambient listening to create a summary, and Live Rewind, which can produce a text snippet that users may choose to save.

The release also arrives with Apple’s privacy overview for Audio Intelligence. The document addresses how the company says it will protect information collected by an always-listening system. According to Apple, raw audio is processed in dedicated hardware, is not stored as a file, and cannot be accessed by the operating system, apps, or Apple.

Apple further says that a saved Siri Recap summary or Live Rewind text snippet is synchronized between devices with end-to-end encryption in the Siri app when iCloud is used with two-factor authentication and the device has a passcode. The features are currently part of the developer beta.
