Siri; your virtual personal assistant
Siri is Apple’s digital personal assistant that is voice-command controlled. The intelligent personal assistant can send messages, dial phone numbers and schedule meetings through voice control. Siri understands the natural speaking voice and will ask questions for clarification if necessary. The new technology takes advantage of the dual-core A5 chip present in the iPhone 4S. WiFi and 3G networks are used to communicate with Apple’s data centers to provide a quick reponse to the user.
