Technically you should be able to run your own back-end, but I ended up giving up on this endeavor when I tried a few months ago. It should be doable if you give it a few good days, but it wasn't very well documented at least when I tried, and there's a lot of different parts you have to get working. After you get it to work, I'm not sure if your server would have a worse data set for speech recognition etc, maybe, maybe not. I'm guessing it should be all right because they are using a Mozilla free data set (which you contribute to by default I think, if you use their server).
