Powered by the S11 chip, Audio Intelligence includes Live Rewind, Siri Recap, Sound Recognition, and Shazam Music Recognition. Sound Recognition and Shazam are already on the watch, but Live Rewind and Siri Recap are now available in the beta. Live Rewind can show you a transcript of the last 15 seconds of a conversation.
