The fact that Apple didn't announce anything using Nuance or Siri technology at yesterday's WWDC keynote is simply because Siri integration wasn't finished in time, according to a source quoted by Robert Scoble. Apple was forecast to use the combination of Nuance and Siri's tech to provide more complex voice functions in iOS 5, such as searching for reservations at a nearby restaurant. iOS devices currently support just a limited number of commands, related to phone calls and music playback.
