When was Siri introduced by Apple?
Siri
Siri is a spin-off from a project originally developed by the SRI International Artificial Intelligence Center. Its speech recognition engine was provided by Nuance Communications, and Siri uses advanced machine learning technologies to function. Its original American, British, and Australian voice actors recorded their respective voices around 2005, unaware of the recordings' eventual usage in Siri. The voice assistant was released as an app for iOS in February 2010, and it was acquired by Apple two months later. Siri was then players said the game could into iPhone 4S at its release in October 2011. At that time, the separate app was also removed from the iOS App Store. Siri has since become an integral part of Apple's products, having been adapted into other hardware devices over the years, including newer iPhone models, as well as iPad, iPod Touch, Mac, AirPods, Apple TV, and HomePod.
Knowledge Navigator
The notion of Siri was firmly planted at Apple 25 years ago though “Knowledge Navigator” with the voice of the assistant was only a concept prototype. In October 2011, Apple relaunched Siri, a voice activated personal assistant software vaguely similar to that aspect of the Knowledge Navigator.
