[citation][nom]house70[/nom]Prolly 1000 little Chinese typing furiously answers so Siri can take credit for it's "intelligence". LOL.Look, speech recognition has been around since Dragon Naturally Speaking, if not even before that. Nothing new here. Any so-called intelligent servers (it's not your phone) that process the requests are based on recognizing key words, like "weather" for instance, and delivering the answer most likely to match (based on your location and some other key words in that phrase). That's why straight questions give you straight answers about 90% of the time, while tricky questions (and the remainder 10%) get some ridiculous answers instead. Of course, all this chat between your phone and the servers, not to mention location services and other involved, tax your data plan and your battery time. Recently Apple said it solved the battery bug present in latest iOS, but in reality it did not, at least not until some of these services are stopped; combine that with the more powerful hardware compared to prior iPhones (that will require more juice, too), and you get back to thermodynamics' law: can't create energy out of nothing.[/citation]
Given that the IA of it all happens on the server, I have my doubts about how much it actually taxes your system. They could even have the voice recognition happen on the device, then have it figure out the correct response on the server.
I'm not really sure how much it taxes your data plan (I don't have Siri to test).
