I would love to know the details here. What I'm suspecting is that Google has figured out a way to combine both client- and server-side processing for both maximal responsiveness and accuracy. Maybe there's even some Google Instant magic going on, so it'll basically predict what you are going to say and pre-fetch something based on that. I don't know much about voice recognition, but I guess it would speed up the client-side algorithm if it has knowledge that your next word is probably going to be either banana or apple.
