Well, technically not really, but practically for the purpose of
updating the user interface it can be considered immediate.

The callbacks are used in Orca for a very similar thing -- the cursor is
moved along the screen according to speech progress.  The movement is,
however, currently only implemented sentence by sentence, so I can't say
if it's going to work word by word.  Anyway, I beleive it should.

Best regards, Tomas.
