Apple’s latest watchOS beta includes its new always-on Audio Intelligence features

Apple has released a new watchOS 27.3 developer beta with two new features: Siri Recap, which generates summaries of conversations using 'ambient listening', and Live Rewind, which transcribes the last 15 seconds of audio detected by the watch's mic. The update also includes a redesigned Health app with new features like an Insights tab and personalized recommendations. Apple has also expanded the language support for the Health app to include 10 languages. Apple has released a privacy overview (PDF) detailing how it protects users' audio data when using Siri's ambient listening feature.
