What if the user is deaf and blind? they are denied access?

Kevin:
For deaf-blind users there are refresh-able braille displays to read
the computer screen. These braille displays are driven by JAWS and
other screen readers (each requiring braille displays drivers).
The braille displaying devices do text-to-braille translations; the
speech synthesizers do text-to-speech translations; while the screen
readers' job is to convert what they 'see' or read on the screen into
text or meaningful output to the HID for the human user.
While this may sound simple, there are other problems, namely
refresh-able braille displays cost a minimum of $1500 US and,
unfortunately, braille is not universal among all of the adult blind
population (which would also include deaf-blind users and adult onset
deaf-blind users).
As for my example (as shown below), the "Speak Key" submit button
works for the blind testers who have tested this for me. While they
have no problem with the way I've done it, none are deaf.

It would be nice if I could get a good female voice, preferably
Asian, who would submit her speech for free distribution. All she
need do is to speak the numbers "one" though "ten" and "repeat" with
pauses between words.
Why Asian? As it turns out a female Asian voice works extremely well
for English speech recognition. I am sure that other languages have
their preferences.
Cheers,
