Has anyone had any trouble using voice recognition with some background noise. Nothing crazy like someone talking right next to ur face while trying to talk to your phone - more like the sound of driving down the freeway at 70 mph. I seem to have to talk much louder to get it to pick up anything when there is more noise. When I'm at home, it works just fine in my house, picking up the emphasis in my voice. I'm assuming there is a noise cancellation thing going on that makes it harder to pick up my voice.
