American School for the Deaf

Like ASL?

Yes, American Sign Language, which was developed in the early 19th century at the American School for the Deaf, is a fully realized linguistic code.

Similarly, LSQ, or Langues des Signes Québécois, serves as a distinct code for Francophone Deaf communities.

Think about live television, too, like a news broadcast or a sports game where you see real-time closed captioning scrolling across the bottom of the screen.
