During the iPhone Duo launch event, Apple unveiled several new Siri AI Audio Intelligence features, including Siri Recap, Live Rewind, Sound Recognition, and Music Recognition. A document released by Apple outlines how these features will maintain user privacy by ensuring that raw audio is processed in a secure environment and is not accessible to the operating system or Apple itself.
The new features rely on the Secure Exclave within the S11 chip found in the latest Apple Watch models. This hardware compartment processes audio data without saving it, allowing users to control when these features are active and ensuring that any transferred data remains encrypted.
