An Atlanta woman has come forward to CNN as the U.S. voice of Siri, the built-in “personal assistant” first introduced in the iPhone 4S. Susan Bennett says she first discovered that her voice was being used on Apple’s smartphones when a friend emailed her and asked if it was her voice on the iPhone commercial. She headed to the Apple website to discover that she had unknowingly provided the voice for the system with samples she recorded in July of 2005, a full six years before the phone’s launch.

Bennett says she had no idea that the voice samples would be used by Apple and that her work also appears on many GPS units and other devices, including the first ATM.

Previously, an Australian morning show interviewed the voice actress who provided the voice for Siri in that country. The interview can be seen below.
