However, there is something new from human ware called "braille
connect" which has onboard and independant processing capability.
There are screen readers for braille only and when we started out in
dos, how I loved the Navigator with it's braille only screen reader.
That was a telesensory product that I'm sure most of us are old
enough to rememberr.

in Braille or speech. This is partially why I encourage the
accessibility of captioning for example even htough screen reader users
are not primary users. But if you want to deliver captioning content to
Braille without using a screen reader, you'll have to develop a lot more
sophistication into the Braille display's software. We're not there
right now."
Let me echo this.
Making information accessible to a Braille display is most often a
function of the screen reader, and could conceivably be added as part of
operating system speech output mechanisms like Narrator. the Braille
display units however, currently would not have any independent capacity
to "synchronize" information, for example in a captioning situation.
Personally I'd consider recommending that we make a requirement for AT
screen reading software that independent usage voice or Braille is
available, to allow people to effectively operate the system using only
a Braille display, or only the voice, or both as they prefer. Having
nospeech is nice now and then, but my experience "lately" is that it is
not as well implemented mostly as it could be.
