In Google Voice Assistant on ICS I could, for example, say "Call the closest Dominos" or "Call CompUSA West Palm" and Google Voice Assistant would start to dial the correct business almost immediately.
Since I've upgraded to JB, Google Now only seems to search my contacts and sometimes brings up map locations of businesses I wish to call. This is extremely disappointing and would really like to know if anyone else is having this issue and if it can be resolved.
