Google has now expanded their pilot phone search to include Mumbai and Bangalore. If you're hungry for some pizza, call 1-800-41-999-999 and say "pizza" . You should also state your location. You will then be presented with a list of pizza places in your area.

We are continuously working towards improving our speech recognition technology but it is still not perfect and it may not recognize you at times. We will transfer your call to an operator after 2 recognition failures who can assist you with your query.
Let's hope Google's voice recognition service does a better job of recognizing accents than it did here.
