I have been hacking on a home automation controller (that isn't particularly well written, to be honest) for a number of years, and voice is one area I do not want to have to figure out how to write myself. I am a bit concerned about having to heavily integrate with a model that requires I explicitly build sentence patterns in their software, because it'd lock me in pretty heavily to that solution.

(My wife has been using Dragon for dictation heavily lately, so that's a use-case that is intriguing to me as well, especially if today's announcement means the death of the Dragon product line in the near future.)
