We recently had the chance to try out Say Who by Excuse Me Services Inc. Say Who is a free voice dialing application that allows you to quickly and accurately dial names or numbers without even looking at your iPhone.

Just launch the application and hold the button as you either speak a contact’s name, or speak the number you wish to dial. Depending on whether or not you have auto-dial on or off the application will automatically dial the number after a few seconds. After displaying the number that Say Who believes you are attempting to signal it gives you a few other close options to in case it heard you wrong.

We tested that application in the field to see how it would perform in day-to-day life. No matter how much background noise there was, Say Who nearly always accurately heard our voice commands. that voice dialer even resumes after the current signal ends.  Say Who is perfect for use while driving. We recommend that application by any played voice dialing application.
