AI researchers from more than 60 institutions worked on the project entitled CALO. CALO is designed to help ease the bureaucratic burden of the military. A consumer spinoff, Siri, is coming to the iPhone later this year. It responds to conversational voice commands to take over multi-step tasks like choosing and booking restaurants or cabs."
