Apple rolled out Audio Intelligence features into testing with the first developer beta versions of iOS 27.3 and watchOS 27.3 on Tuesday, bringing four new AI features that allow Apple Watch Series 12 wearers to detect important sounds, identify songs, catch up on conversations, and take notes. Sound and song detection are designed to detect important sounds like an alarm or doorbell or identify a song using Shazam's technology, while Live Rewind lets users go back to see what was said in the past 15 seconds and Siri Recaps summarize audio throughout the day, saving notes of important things that were said. Apple has taken care to ensure privacy by processing audio and running AI models on-device when possible, and by not identifying speakers, storing raw audio files, and redacting private information like government ID numbers or personal account information. After a day with Siri Recaps, the author sees how its value may outweigh any creepiness factor, and in a real-world scenario at a car repair shop and rental counter, the feature captured key details about time frames, prices, and policies that were delivered verbally too fast to write down.
