This is what I suspected, and this is far from optimum. We *might* be able
to address this with CSS3 Speech, and pause-after
(http://www.w3.org/TR/css3-speech/#pause-props), although we need the SR's
to wake up and smell the coffee here and start doing something with audio
CSS.

Well, ya, that's where I am heading. The question is, would @role be the
right mechanism to do this by? I believe so, but am looking for
confirmation (and if yes, suggest adding it to the list for ARIA.next)

I agree however that this scheme requires a fair number of players to
coordinate to get it right. As Steve Faulkner noted to Silvia Pfeiffer
earlier today, right now it's the browsers that are flattening out the
aria-describedby text, which would break the possibility of this solution
from being viable (in terms of solving i18n issues or for linking to a
longer textual description), so we need to educate the browsers to not do
that. Then we need to help AT understand what we are seeking to do and get
them on board, and finally we need to teach page authors how to do this
correctly. So, ya, a big job, but one worth going after IMHO.
