Adding a human interpreter to an ongoing FaceTime video call

Hello,

In this press release from last month:

https://www.apple.com/newsroom/2026/05/apple-unveils-new-accessibility-features-and-updates-with-apple-intelligence/

It indicates the following: "For sign language interpretation app developers, a new API supports users in adding a human interpreter to an ongoing FaceTime video call."

I have looked over the WWDC26 sessions but have not been able to find any information on this new API. Can you point me in the right direction?

Thank you!
