Voice Search on my VGN worked flawlessly in ICS. In JB, half the time it pauses with "Initializing" for 5+ seconds when I launch it, which pretty much defeats the purpose. You end up talking to yourself. It's bad enough when your kids ignore you - now the phone, too. 
I thought this might be tied to the "Improve Speech Recognition" option, but have unchecked it and the problem continues. Anyone else having this issue?? Suggestions?
