American sign language (ASL) is a visual language using hand gestures, facial expressions, and body movements, primarily used by the Deaf community in North America.

Developed by NVIDIA and the American Society for Deaf Children, a new AI-driven website known as Signs invites people to learn how to sign.

You don’t need to spend any money to start learning American Sign Language (ASL) with these resources.

NPR's Ailsa Chang speaks with Amanda Morris about how sign language evolves over time, the subject of her recent piece in The New York Times.
