But again, why does this require speech? There's sign language. There's braille. Are neither of these languages?

What I'm trying to say is that this isn't really a simple question. We've clearly thrown out the dictionary definition of a language, but these restrictions seem arbitrarily created to disclude programming languages but the way they're done also disclude things we do consider languages. Verbal communication seems like a strange restriction.
