Small keypads are one reason to take advantage of voice commands. Using your mobile on the road is another. Vlingo has a voice-activated service that will help you search, send SMS messages, email, make phone calls or any application with a text field all by speaking into your mobile. The service is optimal for BlackBerrys and supports Yahoo! oneSearch.

Download the application and click the icon on your mobile to get started. After speaking your command, Vlingo will confirm your request before returing results.

Check out the Vlingo website for a video demonstration.
