Re: [orca-list] beginning work on an NVDA like controller

Hello,

I too have not read back over the entirety of this thread but, it seems
to me that what is required does not necessarily need to involve Orca at
all.

It would be very easy to write a shared library which can be linked into
any application and which provides the same kind of functions as the
aforementioned 'NVDA Controller Client'.

The NVDA CC provides basically three functions:

* Is NVDA running?
* Speak string
* Braille string

A shared library that directly links to eSpeak and which will do the
following is easy:

* Speak, potentially interpreting embedded SSML

Not sure if the same level of API access exists in brltty.

Because of the ability of eSpeak to handle SSML it would be possible,
for example, to get applications that are calling it to speak in a
different voice to the one currently selected in Orca.  So, for example,
a MUDD client could speak in one voice while Orca is speaking in the other.

While this is a trivial job, like the NVDA Controller-Client,
applications which use it will have to specifically be written or
altered to use it.

I have briefly looked at the at-spi code and it is a forest.  Hard to
get a handle on, but it's my guess that calling it to get it to speak
(via Orca) probably isn't that hard.

An easier way of going back over previous utterances in a MUDD client
might be to open it in a shell inside Emacspeak(?)  Question mark
because neither have I used shells inside Emacspeak very much, and my
dalliance with MUDD didn't last 24 hours before my attention span
exploded :)

hi
Nods, what storm said. I originally came up with this idea because of
the tintin sound pack for alter aeon, but it might be useful for otehr
apps too. It's not a substitute for proper accessibility, but let me
try and elaborate a bit. I read lots of books, and when I'm in firefox
reading a book and a tell on alter aeon comes in, I get a sound
letting me know it. I then have to alt tab back to alteraeon window,
which isn't hard. But due to alt tab issues in mate this is sometimes
slow, but it always works. I press the key combination to replay back
the last tell to me. WHich, because of terminal emulator issues in
orca it's not always read. If this were implemented, orca would just
interrupt itself with the tell, email, whatever, and then continue
reading. Saves me time and, tbh, is just plain convenient.
Thanks

You'd have to build a Say function into the Orca code and a display
function for the braille that allows you to pass arguments to it
then.  You would then need to find a way to get at the notification
text.  Something like:

while MessageText = true { Say (MessageTextContents); Display
(MessageTextContents); }

The hardest part will be filling the MessageText and
MessageTextContents variables.  This is where an api would come in
handy or you can OCR the text on the screen I guess and then have
the OCR engine return the results.  Probably want a container for
them like a vector so you can hold multiple values in some sort of
a history.  Probably want some sort of timer for how long the
message appears on the braille display function too.   Again, this
is pure conjecture on my part.  Just doing some brainstorming.
You'll probably get suggestions a thousand times better from more
accomplished and experienced coders than your humble servant.

Hth, Alex M

Re: [orca-list] beginning work on an NVDA like controller

Hi, The reasons for being able to send stuff through orca itself is
that people have their speech set the way the like it, and
presenting info this way would use those settings. usually if you
send stuff through spd itself, you get that slow laggy speech
that's also probably in a different accent or language than they
may want. Also, some people may be using braille instead of speech,
and orca could present the info in their chosen medium, where as
spd is limited to speech only. finally, this seems to be a standard
feature in pretty much every other screen reader ever made. I would
personally like a command line flag to do the same thing, instead
of an api, so that scripts could easily present things with Orca as
well, e.g: orca --present-text "hello world" would cause Orca to
say "hello world". On Thu, Dec 11, 2014 at 12:31:20PM -0600, Alex

Hmmh, how about a system call to spd-say to make some text be
spoken.  You would be bypassing Orca altogether and using
Speech-dispatcher.  I don't know Python but, here is some
pseudocode for what I mean:

String notification; Function TalkToMe (Notification) {
System(spd-say 'notification'); }

Admittedly, it's influenced by my smattering of c++ but,
hopefully, you get the picture. Hope this makes sense, Alex M

Afaik this functionality allowed other apps to use orca for speech
output.


Actually that code was not implemented, let alone being called.
So even if it were not removed, other apps could not use Orca for
speech output.

Having said that, Orca is a screen reader; not an app that others
can use to make their app speak whatever they want. So if the
functionality being proposed is screen-reader functionality, it
should be included in Orca. If the functionality is not
screen-reader functionality, then Orca should not be used to
provide it. If the latter is the case, and the problem is just
wanting consistent voice settings, Orca can expose those speech
settings.

Hope this helps. --joanie
