“Siri grew out of a huge project inside the Pentagon’s Defense Advanced Research Projects Agency (Darpa), those people who previously gave you the internet and, more recently, a scheme to encourage people to develop driverless cars. Siri’s parent project, called Calo (Cognitive Assistant that Learns and Organizes) had $200m of funding and was the US’s largest-ever artificial intelligence project. In 2007 it was spun out into a separate business; Apple quietly acquired it in 2010, and incorporated it into its new phone. CALO was an artificial intelligence project funded by the Defense Advanced Research Projects Agency (DARPA) under its Personalized Assistant that Learns (PAL) program. Its five-year contract brought together 300+ researchers from 25 of the top university and commercial research institutions…”
No wonder Siri is so impressive, it had DARPA resources behind it. Siri seems to be revolutionizing the AI scene, causing the public at large to want this type of intelligent listening from all their devices, and hackers re-purposing it to control their lights, thermostats, security systems, etc.
I also did not realize that the iPhone is not doing the heavy lifting - it sends out the voice command to a bank of huge servers which process the information and send back the relevant data.
“When you ask or instruct Siri to do something, it first sends a little audio file of what you said over the air to some Apple servers, which use a voice recognition system from a company called Nuance to turn the speech – in a number of languages and dialects – into text. A huge set of Siri servers then processes that to try to work out what your words actually mean. That’s the crucial NLU part, which nobody else yet does on a phone.”
I wonder if Apple, or this Nuance company keep all of those voice files. Voice files are certainly able to be matched to an individual. If all those voice files are kept in a database, some privacy concerns will probably emerge sooner or later… perhaps after the database is hacked.
