Way to train Voice Dialing?

[Aflaaaak]

I use a Jabra Hands Free doo-hicky in my pickup. It worked fine with my old Samsung Convoy, but no luck with the G4. It pairs fine, connects, and answers calls but gets every dialing from my contacts list command wrong. I tried using Voice Dialing on the phone by itself, and it worked very poorly at getting any commands correct.

My Samsung had a way to "train" the system to my voice, but couldn't find anything similar on the G4. Any suggestions?
