Voice Dialing is one of the more useful features missing from the iPhone. Users therefore have been turning to the App Store for a voice dialing app that is both reasonably priced and accurate at the same time.Â Perhaps one of the most popular ones at the moment is Say Who, a free app that works reasonably well. The simple interface works well especially when you are trying to make a call while driving. Once the app starts, you can press down anywhere on the screen and say your contact’s name. Say Who will accept first and/or last names, nicknames as well as digits of the contact. When a contact is found, the default setting of AutoDial will automatically connect you to the first of the results found in about 3 seconds. Turning AutoDial off will allow you to choose which of the returned contacts you want to dial.
