aloha!

one area where speech-characteristic changes and aural icons is needed
is in conjunction with ARIA 1.0 markup -- for example, to indicate the
presence of a "describedby" value for an image or to aurally demarcate
the text which is referenced by the "describedby" property if the user
has her speech engine set to "read describedby text inline" as opposed
to using the cue-before and cue-after mechanism to "indicate presence
of describedby text" or "indicate presence of describedby text and
speak aria-labelledby/label"

in addition, ARIA-demarcated states -- such as "checked" and "unchecked"
-- could be communicated non-verbosely to a user using the aural cueing
model contained in css3-speech...

the use of css3-speech in conjunction with ARIA should probably be
addressed not in the css3-speech recommendation itself, but in one of
the ARIA support documents, such as the WAI-ARIA Authoring Practices
Guide:

* http://www.w3.org/WAI/PF/aria-practices (latest editor's draft)
* http://www.w3.org/TR/wai-aria-practices

also, WCAG should contain a section on the use of css3-speech to
control/guide spoken output -- i would be more than willing to assist
in the drafting of any such text, gregory.
