I did the voice training twice and it made a big difference.
I also found that it recognizes some words better than other. You can just watch the VA screen to see how well it recognizes particular words. I gave up on F1-F12 and used function one - function twelve. Works much better for me.
Also "back slash" is iffy. I just say "comms menu". I should make a video.
Voicing was never an issue, not at all. It worked great in that regard. VA was always causing some conflict or another... it's been so long I can't really remember exactly what it was. One day though, I just said F'it and deleted it. Figured eventually someone would come up with a more seamless product. Looks like they have.
Could be I'm just getting old and don't have the inclination to mess with stuff to get it working. Same story with me & VR. I have a G2 that spent maybe a month not sitting on it's wall mount... there's a nice coat of dust on it now. It was just one thing after another. I should've waited ~another~ 10yrs.
