Unbeknownst to many people, the voice of Siri isn’t a computer-generated  simulation of a human voice. Susan Bennett is the voice behind Siri, a professional voice actor who has taken the role as her own ever since the program was first introduced with the iPhone 4s in Oct. of 2011. The project of becoming Siri was the largest that Bennett had ever attempted, starting way back in 2005, when the idea of Siri was just a distant idea to the masses.Bennett had to perform four hours of recordings every day until 2008, for a total of over 100,000 hours. ScanSoft, the company heading the project, tossed any word they could think of at Bennett, since Siri, as a program, is designed to posses as full of a vocabulary as possible .

Even though the Apple corporation cannot officially confirm that Bennett is Siri, and Bennett’s lawyer is restricted from sharing contracts and deals with Apple, audio forensic detective Ed Primeau was able to confirm Bennett as the voice of Siri. Performing back-to-back comparisons of Siri and Bennett’s voice, he was able to confirm that Bennett as the voice of Siri.

However, with the introduction of iOS7, which introduces a new Siri, Bennett can now come out as the original Siri, even though her time as the iPhone assistant is coming to a close.
