Nvidia taps AI to teach sign language

How it works: Signs guides ASL learners through the process of forming words, using machine learning and computer vision to assess progress.

• Language learners can access a library of signs that have been validated by people fluent in ASL. An AI tool then analyzes the signs users make and offers feedback.
• Experienced signers can contribute videos, which will be reviewed and added to the tool. Nvidia says its goal is to grow the database to 400,000 video clips representing 1,000 signed words.
• The tool is available starting Thursday.

What they're saying: "Most deaf children are born to hearing parents," Cheri Dowling, executive director of the American Society for Deaf Children, said in a statement.

• "Giving family members accessible tools like Signs to start learning ASL early enables them to open an effective communication channel with children as young as six to eight months old."
