Search Contacts with all Voice Search Commands? Is there any way to integrate voice search's navigate to/directions to/map of commands with your contact list? If I want to go to Bob Jones's house, I don't want to go to Bob Jones Co.
Have you tried navigate to bob jones home?

You can use the label on the address when using the voice command. The above command is different than navigate to bob jones work.

Update: One thing to remember: Your contacts need to be accessible to the Google Servers. In other words, you need to be syncing to your Google account. The actual voice-to-text work is done on Google's servers, not on your phone. (Try using voice search while in Airline mode.) See this Google Support thread.

And, of course, your Contacts need to be in your "Searchable items". (I get there by hitting the search button, then the blue 'g' to the left, then the settings icon.)
