Can Google Voice Search be configured to confirm name before calling? When making a call using Google Voice Search, I would like my phone to ask for name confirmation.  So, if I say, "call Gina...", I want it to ask me if I meant "call Tina" before dialing.  (suddenly, I feel like I'm in an old Sprint commercial...)

I would like it to confirm ONLY when using voice dialing and would strongly prefer audio prompt.
Have you tried 3rd-party solutions?  Call Confirm app on the Market seems to do exactly what you need.  I just installed it and can confirm that it works in conjunction with other apps (Voice Search, Google Voice, etc.)
