Learning to sign is a great start. For the moments that have to be right (a medical appointment, a parent-teacher meeting, a legal conversation) Ava connects you with a credentialed ASL interpreter over video in the Ava app, on demand or scheduled ahead. Available 24/7, with live captions included.
