Google Voice Local Search is Google’s experimental service to make local-business search accessible over the phone.
To try this service, just dial 
1-800-GOOG-411
(1-800-466-4411) from any phone.
Using this service, you can:
- search for a local business by name or category.
You can say "Giovanni's Pizzeria" or just "pizza". - get connected to the business, free of charge.
- get the details by SMS if you’re using a mobile phone.
Just say "text message".
