Siri –The Intelligent Personal Assistant.

• Siri is an intelligent personal assistant and knowledge navigator which works as an application for Apple's iOS.
•  Talk to Siri as a friend and it can help you get things done – like sending messages, placing calls and reserving a table and so on.
• Siri is a virtual assistant with a voice-controlled natural language interface that uses sequential inference and contextual awareness to help perform personal tasks for iOS users. And, like most of the other keytechnological features in Apple‘s iOS products, SIRI has its roots in federal funding and research. 
•  SIRI is an artificial intelligence program consisting of machine learning, natural language processing and a Web search algorithm (Roush 2010). Spun out of the DARPA-funded CALO project, Siri was initially developed by Dag Kittlaus and his team of SRI International as an iPhone app.
• Apple bought Siri in 2010. Siri is currently run by Bill Stasior, vice president, Siri, and the technology is integrated into the iPhone, iPod touch, and iPad, and into Apple's new HomeKit home automation framework.
