Maybe this will be different, and that'd be neat. Though I just think more expressions of code is neat. I also know the accessibility you're talkin about isn't for blindness.
That being said I can talk about code decently well, but if you've never heard code come out of text-to-speech, well, it's painful.
I bring up the text-to-speech because if speech is input, it would make sense for speech to also be the output. Selfishly, getting a lot of developers to spend time coding through voice might end up with some novel and well thought out solutions.
