In December 2011, Vlingo was acquired by Dragon Go's maker, Nuance. Responding to your voice command, Vlingo can compose an email, a text message, a calendar reminder, a Facebook status or a tweet. You can also make calls and get directions. This free app will read your words back to you before your email message, for example, is whisked off. If you're behind the wheel, Vlingo has a hands-free car mode that lets you accomplish tasks with your voice alone -- no need to fumble around to tap your phone's screen. Vlingo also can handle rudimentary searches by voice. For instance, you can say "convention centers near Savannah." However, Vlingo's search results lack the more-unbridled scope of the responses delivered by its cousin, Dragon Go. Vlingo is compatible with iPhone, iPod touch, and iPad running iOS 4.0 or later.
