I can at least confirm this.  I don't know of any workarouns, and have
just learned to ignore the extra speech.  I believe the problem is with
the way zsh uses the terminal: it would seem to redraw something so that
speakup thinks the screen has been updated.
I don't know this for certain, but it seems logical to me.
Incidentally, could this be the problem with vim as well?
Best,
Zack.
