Further cementing Google Maps Mobile as one of the most useful free mobile applications ever, Google has added Voice search to its repertoire. It’s an experimental feature at this point, so it’s only on select handsets; if you’re using a Blackberry Pearl 8110, 8120, or 8130 – go update!

The new feature seems pretty easy to use: hold the left soft key, say your search, release the left soft key, and off it goes. It utilizes the same speech recognition engine used by 1-800-GOOG-411, which (based off my past experiences with it) is a good thing. Still, typing still works fine, allowing you to fall back on your thumbs be it that your environment just doesn’t mesh well with voice recognition.

While I’d be a bit surprised to see this feature make it into the generalized J2ME version of the application, we’ll probably see it to roll out to other big-name platforms as Google works out the kinks.
