Didn't mozilla also have a related speech to text software that got canned/moved to a different company? Or was that different?
Seems more likely that Mozilla would have shut down both projects, but NVIDIA funding saved the more important one.
EDIT: Nvm, there seems to be a new project called Sayboard that does everything on your phone:
https://github.com/ElishaAz/Sayboard
(though switching from Swiftkey is a bit annoying)
