I think you have it exactly backwards - the iPhone 4S/Siri speech-to-text/natural language processing are done in the CLOUD. The text-to-speech is done on the phone itself. My (non-Siri of course) iPhone 4's Voice Command stuff is COMPLETELY on the phone itself, and would do TtS of my contact list and Artist names, etc.

The article says, "The iPhone 4S really sends raw audio data". At least for Siri, TtS occurs on the cloud - not sure where the text processing > API occurs though.
