> "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."
Android phones have been doing this long before Siri came out. I am still amazed (and annoyed) at how often people claim Apple to be the first to produce things without even the smallest bit of research to see if it's actually true.
