Ok, wrote clean instance of ubuntu mate operating
system .img to the one SDCard for my raspberry pi B+ v.2, plugged in USB
keyboard, as well as a generic, cheap, external USB audio adapter, plugged 3.5mm
audio jack for speakers into it, and powered up the pi using the portable mobile
phone charger.
Heard the speakers initialise after roundabout 30
seconds, and waited a further 30 seconds, and then hit ctrl + S, and orca screen
reader started talking, with no hiccups, stuttering, pauses, etc., so seems like
the pi can make use of the external audio adapter, and thus take the load off
it's internals, etc, and thus work with gnome, orca, and e-speak
combination.
Now, next issue is that all orca seems to be
reporting to me in the GUI/gnome interface, almost all the time, is
"japanese/chinese characters" - that same phrase over and over
again...<smile>
This is either if I hit alt + F1, to try invoke
menu system, f10 for other form of menu, or if I hit alt + F2 to bring up run
dialogue, I can type in text and select it, but, it seems to be telling me
something about tokyo, etc.
In other words, definitely seems like this might be
a usable/viable option, but am guessing that the GUI's character-set/language is
set to something like an odd/asian character-set, and orca is just repeating
characters/encoding to me that it can't pronounce using the default voices,
etc., since if I hit alt key, it reports left alt, etc.
Any thoughts on what I can try changing in
something like the config.txt file, or something else to make sure it's using a
compatible character-set or language, etc., or is there something else I should
try..?
Either way, am just pretty much impressed that the
pi, from initial bootup, immediately started routing audio output via
my external USB audio adapter, and this, again, just shows you that almost
anything is possible/doable, if you try a couple of alternatives - like the pi
itself...LOL!
Stay well
