I completely agree with you that it's much better than Sphinx/Pocketsphinx. It's even much better than Microsoft's built in speech recognizer that's been around since XP. But it is still very bad compared to the recognition available via Google's voice API and that was the point. Also, I was trying to explain that given the types of models used today for recognition, inherently models trained and hosted somewhere are going to be bigger and more accurate than ones deployed on the field.
