If you haven't checked out 1-800-GOOG-411 yet, you should.  It is 100% voice recognition driven directory assistance (wow that was a mouthful).  You call up, it asks for the location.  It will then respond back with how it heard the location and you can confirm.  It will then ask for either a category or business name.  Once you state it, it will begin to respond with search results.  When you hear a result that you like, you tell it the number and it will connect you. 

The best part of all is that the service is completely free!  No more $1.00 411 calls!  Check it out next time you get ready to dial 411.
