That's an interesting use case that we could potentially explore down the line, thanks for sharing!

Right now, we're focusing on non-native English speakers, as it's a problem that we personally understand best -- as well as a very large market.

I just want to note that for many deaf people (including practically all people that were born deaf) sign language is their first language, and thus, technically, English isn't their native language.

edit: I'm also curious to know more about what kinds of analysis/algorithms you do to detect the accent, if you can share a little bit. Can your app distinguish between different American accents? Or could it hear the user talking in African-American English and assume it is "incorrect"?
