I installed it a couple of hours ago and tested it out about a dozen or so times and it's worked perfectly on almost all of them. Some things can obviously be spoken clearly and it nails those every time. Other things I knew it would have a problem with, and it required some correction. For example, there is a restaurant near me called Akasha Restaurant. So, speaking as clearly as possible, I said "Akasha Restaurant in Culver City California." It came back with "A caution restaurant in culver city california." So, while not perfect, I'm actually very impressed with this program. I think it's a keeper.
