Google recently launched voice-enabled search, but they're hardly the only players in the game and certainly not pioneers. One of the companies making headway is Vlingo, who recently released a free voice-enabled app for the iPhone that lets users make calls, search the Internet (Yahoo and Google), search maps and update Facebook and Twitter profiles. The app can be found at the App Store.

In late October, Vlingo also announced upgraded features for their voice application for BlackBerry. Using the newer models, users can update Facebook and Twitter, speak text messages, call a phone number, and open any number of BlackBerry applications (address book, browser, calendar, etc.) Check out Vlingo's website for some demonstration videos.
