Google Voice Local Search

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.

And it's free. Google doesn’t charge you a thing for the call or for connecting you to the business. Regular phone charges may apply, based on your telephone service provider.

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".
  

Note: Google Voice Local Search is still in its experimental stage. It may not be available at all times and may not work for all users. We’re fine-tuning the service to get better at recognizing your requests. It’s currently only available in English, in the US, for US business listings.
