How AirPods Pro will know when you're trying to silently interact with Siri

In addition to revealing its initial plans for AI and annual updates to iOS, macOS and more at WWDC 2024, Apple also discussed new capabilities coming to the second-gen AirPods Pro. Siri Interactions will allow you to respond to the assistant by nodding your head yes or shaking your head no. Apple also plans to introduce improved Voice Isolation that further reduces background noise when you're on a call. Both of these items are exclusive to the most recent AirPods Pro, because they rely on the company's H2 chip like existing Adaptive Audio, Personalized Volume and Conversation Awareness features. Like those advanced audio tools that are already available on AirPods Pro, Siri Interactions and Voice Isolation use the processing abilities of the H2 chip in tandem with the power of a source device -- an iPhone or MacBook Pro, for example.
