aloha, ian!
i agree with your proposal, save for your caveat:
quote
IMPORTANT: I propose that we delete "and other articulation
characteristics" from checkpoint 4.11 since that makes it
much harder to specify minimal requirements.
unquote
it wouldn't be much harder to specify minimal requirements for "other
articulation characteristics" if you simply applied the same implementation
example to that phrase that you used for volume -- the aural media rules of
CSS2... the minimal requirements for "other articulation characteristics"
should be those listed as "speech characteristics" [1] in chapter 19 of the
CSS2 recommendation that aren't already highlighted by separate UAAG
checkpoints -- namely:
voice-family;
stress;
and richness
the minimal requirements should also list equivalents for CSS2's
"speak-properties" [2]:
speak-punctuation and speak-number
and for CSS2's "speaking-properties" [3]
normal, none, and spell-out
as well as the "pause" properties [4]
pause-before and pause-after
all of which are elemental aspects of a speech synthesis engine... cueing
is pretty damn important, as well, but i think that i'd settle for the
above as "minimal", although i'd prefer a self-voicing UA to also implement
some sort of cue-before and cue-after configuration option, as well as a
play-during configuration and control
