Vlingo Corporation has announced the release of its new vlingo application for the iPhone. The new voice-powered app enables users to initiate calls, search via Yahoo! or Google, look up locations and search Google Maps, and send Facebook and Twitter status updates, all without typing. Unlike Google’s slightly-controversial implementation of voice search, which used unpublished APIs to automatically prompt for voice search, vlingo uses an on-screen button, which is held down while speaking. A demo video of the application is available online. Vlingo for the iPhone is available now as a free download from the App Store.
