Hello Michael,

It seems there was some work done in this regard to define a tts api
that providers could conform to.  I don't recall if it was dbus based,
but more information can be found here:  There is even a python provider
implemtation but I'm not
sure how fully developed it is.  At the bottom of the api page it says
discussion for the api takes/took place on
accessibility at mailinglist.  That may be a place to
look for more background too.
