A woman from Georgia has answered the question on everyone's mind.

Her name is Susan Bennett and she is the voice of Siri on the iPhone. Millions of American's use her every single day. Whether it be to get the weather, find a restaurant or ask some kind of absurd math question.

Apple won't confirm or deny if Bennett is the voice however, Bennett has been working with voice professionals who have confirmed her claim.

With the drop of the new iOS 7 Bennett is slowly being replaced by other voices as users can choose from various accents and voices for their iPhone's 'Siri'
