This would be an awesome voice control addon for XMBC/media play services from a Pi!
Like, Siri has to be online cause everything is processed on Apple's servers because there are so many things Siri could do. But if all I want is to be able to say "play <NameOfMovie/TVShow>", I would love it if that could be done offline. Even if I had to train the system myself.
Say I have 30 TV Shows in the library, I could see myself train the system the names of all of them if that meant I am able to actually start them via voice.
