Google Voice Local Search has emerged from the Google Labs to provide free directory assistance. A call to 1-800-GOOG-411 connects you to a pleasant automated operator who asks for your city and state. From there, you can narrow your search by business or category. When Google finds your business, it offers to either connect you for free, or text the details to your phone. The service does not currently support ads.
