Re: pulseaudio

["T. V. Raman" <raman@xxxxxxxxxxx>]

The reason they "talk over each other" is that orca does not shut
up when used with a self-voicing application. This had been one
of my first asks of all screenreader developers when those
efforts started with the work on ATK in early 2000 --- sadly it's
been mostly ignored.

You can tell orca to mostly shut up by creating an Emacs.py
script for orca that passes on all events. However orca *will*
speak when you type characters etc --- which makes the whole
thing completely unusable -- not just slightly.
At this point there is nothing that can be done from the
emacspeak side to alleviate this -- other than recommending that
if using both emacspeak and orca, then you either run emacspeak
at the console --- or you kill orca when you start emacspeak.

Note that running emacspeak at the console loses little, since
with Emacs 23 (CVS) you can now open a frame on the running emacs
from the X side --- launch emacsclient at a terminal under X, and
it'll open a frame on the emacs you started on the console.
