SRI International
In December 2007, SRI launched a spin-off company, Siri Inc., which Apple acquired in April 2010. In October 2011, Apple announced the Siri personal assistant as an integrated feature of the Apple iPhone 4S. Siri's technology was born from SRI's work on the DARPA-funded CALO project, described by SRI as the largest artificial intelligence project ever launched. Siri was co-founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (vice president, engineering), and Tom Gruber (CTO/vice president, design), together with Norman Winarsky (vice president of SRI Ventures). Investors included Menlo Ventures and Morgenthaler Ventures.
AirPods
In addition to playing music and relaying phone calls, AirPods have support for Apple's digital assistant, Siri, and a physical user interface which can detect taps and in-ear placement. AirPods include the proprietary Apple W1 SoC, whose additional connectivity functions require devices running iOS 10, macOS Sierra, watchOS 3, or later. They automatically sync through Apple's iCloud service allowing users to switch audio sources to other supported devices connected by the same Apple ID. They can also function as standard Bluetooth headphones when connected to any device that supports Bluetooth 4.0 or higher, including Android devices.
