Did I mention Kickstarter? I just can't recall that o_O... then again I can't remember what I did this morning. The Dragon SDK is like $5k to get on board and I'm not sure what the distributed libraries will cost per user. There would be added cost, I'm sure. I actually have a pending message in with the Dragon people (Nuance)... I am small potatoes and they've got bigger ones I'm sure (probably for the best). It would be nice to find out the details at least.
Pfeil is right, though. Phrase recognition with a trained speech engine doesn't leave much to gain by going to Dragon. Otherwise, an alternate speech engine would already be in place. Dictation is another story, though. My untrained iPhone (Dragon, right?) seems to work just as well as my trained Windows engine. They each seem to make their own mistakes, but the iPhone seems to handle contextual stuff a little better (to test I just hold my iPhone up in front my face at the same time I'm talking into my headset).
I am looking at alternatives, but I keep in mind that dictation is not the primary feature that users of VoiceAttack are looking for. Like Slan said, I have to weigh supporting the wants and needs of the majority of VA users versus creating a feature there may be little interest in. It wouldn't be a complete hassle to drop in a new engine, however, I'm sure there is (just as there is with the Windows engine) eight billion anomalies to sort out... and that could take a lot of time (and the pulling-out of a lot of hair).
