The free download (for PC only) lets users record their own voice directions and load them onto compatible Garmin nüvi devices (Here's the list; all but the nüvi 300 and 600 series are supported.) Garmin says the process of recording directions and loading onto a device takes roughly 30 minutes.
Voice commands can be recorded for any of Garmin's standard instructions, such as "Enter Roundabout" and "Make a U-turn." Users can also share customized voices with each other, which I bet would make for some great pranks -- "Turn left! No, wait, turn right! Actually, you'd better just turn around. I'm lost. Sigh."
While Garmin's Voice Studio sounds like fun, I have trouble seeing it as anything more than a gimmick. As far as gimmicks go, it's a good one, though.
