Siri

Siri is the voice-input, voice-response artificial intelligence personal assistant software originally developed by SRI International for iOS devices in the mid-2000s and later for macOS computers. Siri was acquired by Apple Inc. in April 2010 under the direction of Steve Jobs, former CEO and co-founder of Apple.
