I have a Droid RAZR Maxx that links to my Google Contacts. I would like to add several hundred business contacts that I do not want the Voice Dialer to see. I call them rarely and don't want to slow down the voice dialer by making it search through them. I'm also concerned the dialer will be less accurate with so many contacts. Is there a way to specify Google Contact Groups that are not searched by the dialer? Or, are there separate contact apps that don't interface with the voice dialer that I can use to manage these business contacts?
