Would like to get a consensus from everybody with the g'Zone. Does voice command work?

Mine is totally useless, doesn't recognize anything I say. Was wondering if this is endemic to the type phone or do I just have a bad phone that needs to be replaced?

Part of the reason I got a phone with a speaker phone capability is to be able to use it hands free and without looking at the screen to dial while driving. I've got 51 year old eyes, and the font of the menu screens is so tiny, I can't read anything on the screens when I am driving, so I need to be able to use voice command to at least dial out.
