Yahoo! has teamed up with Vlingo (not to be confused with Vringo) to offer speech recognition in their mobile web search app. If you’re in the US on a Pearl, Curve, or 8800-series BlackBerry you can snag it here. It worked pretty well in my brief test, getting most of what I said right even when I sort of mumbled, although it seemed to have a little trouble with background noise. There are plans to make it work on more devices and in more countries too, so hopefully more people will be able to get their hands on it soon.
