On November 3, 2026, the Audio Intelligence feature Apple introduced for Apple Watch entered developer testing with iOS 27.3. According to a TechCrunch AI report, the feature includes four optional functions: Sound Recognition, Song Recognition, Live Rewind, and Siri Recaps. Live Rewind lets users double-click the Digital Crown to review the text of the last 15 seconds of conversation, and unsaved segments are automatically deleted after 30 seconds; Siri Recaps generates only key-point summaries, does not save the original audio and does not produce verbatim transcripts, and unsaved summaries are deleted within 7 days. Audio is processed in the watch's Secure Enclave, converted into condensed text via iPhone, and then handed to Private Cloud Compute to generate summaries; it is available for Apple Watch Series 12 and Apple Watch Ultra 4. The next day, 9to5Mac reported that Apple released the first beta of watchOS 27.3 to developers, bringing Siri Recap and Live Rewind to the same two watches, and stated that the two features do not create or store audio recordings, that summaries and segments are end-to-end encrypted, and that audio is isolated and processed with the help of the Secure Exclave in the S11 chip. The feature is currently still in developer testing.

Apple watchOS 27.3 Developer Beta Launches Audio Intelligence Always-On Listening Feature
Apple has introduced the Audio Intelligence feature in the watchOS 27.3 developer beta, allowing Siri to access the Apple Watch microphone. The new Siri Recap generates conversation summaries through ambient listening, while Live Rewind generates a text transcript of the last 15 seconds of audio captured by the watch microphone. Apple also released a privacy statement, saying that raw audio is processed within dedicated hardware and is not saved as files, and that neither the operating system, apps, nor Apple can access it; summaries or transcript segments that users choose to save are synced across devices in the Siri app via end-to-end encryption. The iOS 27.3 developer beta also opened testing of a redesigned Health app, adding an Insights tab and personalized For You recommendations, and expanded language support to include Simplified Chinese, Traditional Chinese, French, Japanese, Korean, and others.
