If you run emacs in the terminal, you might need to pass
the argument -nw to it, to make sure it starts up in text-mode.
Emacspeak should work fine in a text-mode emacs session,
at least that is how I was using it several years ago.

If you have a patched screen and run emacs -nw inside of it, BRLTTY
should be able to see the screen content and present it to the user.

P.S.: I'd be interested where setting up Emacspeak for Mac is
documented?
I might want to do that on my Mac as well.
