Linked Contact / Voice Dialing

[Space Cowboy]

I've read a couple of threads about people having a similar problem I'm having with voice dialing. Based on what others have said, you need to have a linked contact with GMail for voice dialing to work. However, I'm still having the same problem that others are having which is when you press the mic, and say "Dial Tom", it only opens a web page search instead of actually dialing the number. What am I missing?
