this is not kindle or fire related but screenreader related if you run nvda.
today, listened to the latest podcast for eyes on success which
featured this program.
in the works is a patch for jaws and window eyes.
but, i ran this add on on my lowly winbook 7" tablet running windows 8.1.
not perfect, but, amazed nevertheless!
on my tablet the "bridge" works with nvda and microsoft speech recognition.
the "bridge" gives you responsive feedback of everything spoken and written.
i tried gmail, notepad and facebook. worked in all.
might want to give it a try. link below.
