Basically, you dial 1-800-GOOG-411 (1-800-466-4411) from a phone (I suspect a pay phone works also) and tell it what you want.
I tried it out by calling myself in my office.
- Dialed number
- GOOG 411, experimental
- What city or state?
- What business name or category
- Listed business details and said I'll connect you
- The phone number that the Caller ID displayed was 800-466-4411
So I suspect kids can use this to dial the local bar and play prank calls. Here are some ideas on prank calls Bart Simpson used. :) I would think Google has thought of this, so I am not too worried. Heck, they have tons of web spam filters, so applying some of those brains to prank calls, can't be too hard?
In any event, the voice recognition worked very well, even over a speaker phone. It was easy to use and I liked it.
