BlackBerry's had rudimentary voice commands for quite some time, like "Call," "Check Signal Strength," and "Check Battery," but nothing that really rivals Microsoft's Speech, Google Voice Actions, or Siri on iOS. RIM appears to be moving in that direction, though, as a recent update for the BlackBerry 10 Dev Alpha demonstrates. CrackBerry tried out the update, and as the publication explains in the video below, you can just hold down the developer handset's Play / Pause button to access a universal search function, get driving directions (served up via Bing Maps), check the weather in the city of your choice, and set calendar appointments using the experimental functionality. Crackberry also claims the voice commands hook into the phone's music player as well.
