I never understood the need for server-side speech recognition. Did an internship in 2013 for speech recognition on a BeagleBoard with Julius (https://github.com/julius-speech/julius), the thing worked with ninety-ish % accuracy (japanese language) and delay comparable to what my tablet gives - but locally.
I always figured doing it server-side was just to capture the users' data,either because the company wants a big training set, or for more nefarious purposes like tagged advertising.
