Google has released a voice search experimental feature in Google Maps for mobile. The new experimental feature is only available in the US and is only available on 3 BlackBerry Pearl models (8110, 8120, and 8130). The technology ties together features of Goog-411 into Google Maps for mobile.

Using voice search is as simple as 1, 2, 3:

   1. Press "0" to center the map view around your location
   2. Press the left-side key and hold it while you say the name or type of business you're looking for (for example, "pizza")
   3. When you're done speaking, release the left-side key, and our voice recognition technology will figure out your request and find the business you've been looking for, no typing needed.
