Siri: A Cloud Based Digital Assistant for the iPhone

"Siri is a new generation virtual, digital assistant that is meant to act just like a human assistant. It understands what you say, accomplishes tasks for you and gets better at understanding what you want as you spend more time with it.

Initially available as an iPhone application, Siri can make reservations at restaurants, find movie times, provide weather forecasts and accomplish other relatively simple tasks. Siri uses speech recognition software, so you have the option to speak or type commands."
