Siri
Siri is the intelligent assistant that enables Apple iPhone, iPad and iPod Touch devices to understand natural language voice commands. Talk to Siri as you would to a friend and it can help you get things done — like sending messages, placing calls, and making dinner reservations. You can ask Siri to show you the Orion constellation or to flip a coin. Siri works hands-free, so you can ask it to show you the best route home and what your ETA is while driving. It works with HomeKit to let your voice be the remote control for connected products in your home.
