iPhone 4S : What is Siri?
Siri on the iPhone 4S is the intelligent personal assistant that helps you get things done just by asking. It allows you to use your voice to send messages, schedule meetings, place phone calls, and more.
But Siri isn’t like traditional voice recognition software that requires you to remember keywords and speak specific commands. Siri understands your natural speech, and it asks you questions if it needs more information to complete a task.
Siri uses the processing power of the dual-core A5 chip in iPhone 4S, and it uses 3G and Wi-Fi networks to communicate rapidly with Apple’s data centers. So it can quickly understand what you say and what you’re asking for, then quickly return a response.
Siri is currently in beta and Apple will continue to improve it over time.
