Apple Watch Series 12 and Ultra 4 add AI listening features with on-device privacy safeguards
Apple's new Watch Series 12 and Ultra 4 include four opt-in 'audio intelligence' tools—sound and music recognition, conversation recap, and a 'Live Rewind' feature that transcribes the last 15 seconds of ambient speech. Apple says these features rely on the microphone but don't record or store raw audio, processing most data locally via a new secure chip component called the Secure Exclave, with any cloud processing handled through Apple's Private Cloud Compute system.
