apple's latest watchos 27.3 developer beta introduces audio intelligence features, including siri recap and live rewind. siri recap uses ambient listening to generate summaries of conversations, which can be reviewed later in the siri app. live rewind provides text transcripts of the last 15 seconds of audio detected by the watch's mic, allowing users to recall missed information. apple has also released an audio intelligence privacy overview, detailing measures to protect users' privacy, such as handling raw audio within dedicated hardware and end-to-end encryption for saved summaries and text snippets. these features are available for apple watch users who opt into the beta program.
