Apple Siri is a digital voice assistant developed by Apple Inc., first introduced with the iPhone 4S in October 2011. The name "Siri" is derived from the Norwegian name Sigrid, meaning "beautiful woman who leads you to victory". Originally, Siri was a spin-off from the Stanford Research Institute's Artificial Intelligence Center and was part of the US Defense Advanced Research Projects Agency's (DARPA) funded CALO project
