Apple's new Apple Watch Series 12 and Ultra 4 introduce Audio Intelligence, a set of AI-powered audio features including sound recognition, automatic song identification via Shazam, live speech recall (15-sec transcript), and conversation summarization. While useful for accessibility and productivity, the feature raises privacy concerns—Apple clarified that most features require user opt-in, data is encrypted on-device or via iCloud, and transcripts auto-delete within 30 seconds to 7 days. Currently limited to English language support.
