[Emacspeak] Re: Introducing myself and a request

That's interesting, as Voxin works fine with Fedora, which natively uses Pipewire, not Pulse, but does have translation layers for packages that use Pulse and ALSA.

Hi Francisco,

today I setup a virtual host running arcoLinux. I installed pipewire and found that for some reason, the espeak
server will not work with pipewire. I have no idea why it won't work - possibly espeak-ng needs to be built with
native pipewire support or perhaps some other translation layer needs to be installed. Problem is, I don't know enough
about pipewire to diagnose the issue.

At this point, I would say your out of luck with respect to using Emacspeak and pipewire.

In case it is of interest to others, here is what I found.

• You can build the tclespeak.so library fine.
  
• when you run servers/espeak, you here espeak say "Espeak 1.50"
  
• At the % prompt, if you do q {Hello World} <ret> d <ret> the server just
  hangs. No speech and the prompt does not return.
  
• If you then attempt to run Emacs with Emacspeak, all appears to work, but after the initial "Esepak 1.50" announcement, you get no speech and no errors. Auditory icons with sox worked fine.
  

I was running espeak and pipewire fro the official arch repositories. I've not yet tried using the packages from community/aur, which may be later and which may work better. My suspicion is that espeak needs to be built with native pipewire support (previously, I found you could build espeak with specific support for pulse, port audio or alsa. Not sure if it yet has pipewire as another supported sound library.

Tim

Hello there,

Thanks again for the answer, I got a step further!

Now, when I start emacs, both from gui and terminal espeak speaks it's version, and what sounds like eloquence announces in my left ear, this is emacspeak!

However, when I try to navigate with arrows, tab, or anything else, nothing works. espeak doesn't talk, no sound icons can be heard either.

Any idea why?

Thanks again, and thanks for the tip about replying to all, I read it, and I forgot about it.

Best regards.

Francisco.

OK. You will want to go through the Emacs tutorial at some point. As
emacs is an old editor, some of the terms used can be a little confusing
at first. This is partly due to the age of the editor and partly due to
certain terminology being hijacked and changed. For example, what other
systems call a window, emacs calls a frame and what emacs calls a window
is more similar to what other systems call a pane or tab or even buffer.
So a frame can have multiple windows and these windows will contain
buffers. You will also hear about key bindings (similar to shortcuts)
and many other unusual terms (like yank for copy). Thing is, persevere
and you will get there. You will find the key bindings (shortcuts) to be
a little strange, but avoid the temptation to change them initially.
There is actually a lot of logic and consistency in them once you get to
know them. One thing great is that you can do everything just using the
keyboard - much faster than using a mouse.

OK. Emacs can run either in GUI mode (with its own frames (windows) or
it can run inside a terminal emulator. I prefer to use it as a GUI.

OK, you will probably want to run Emacs in GUI mode. If you run int in
gnome terminal, you may run into conflicts between Emacspeak and Orca.
If you run it in GUI mode, you can have both Emacspeak and Orca running
at the same time.

Emacspeak is one of those few programs which are far better run directly
from the git repository. I would uninstall any Emacspeak package you
have installed with yay or pacman. Instead, do the following

Check out the Emacspeak git repository into a directory in your home
directory e.g.

git clone https://github.com/tvraman/emacspeak .


Then change into the native-espeak directory with

cd emacspeak/servers/native-espeak

and run make to build the espeak shared library used by Emacspeak. You
will need the tcl and espeak development files. I'm not sure what the
convention is under Arch, but under Debian/Ubuntu, these are usually
called something like libespeak-dev and tcl8.6-dev or similar. If the
make runs without errors, you then need to verify the server works by
changing into the servers directory and running the command ./espeak.
You should here the espak server speak the version and then be left at a
tcl promp e.g. a %. You can then enter

q {Hello World} <enter>
d <enter>

and you should here the server speak "hello world". If this all works,
then you need to change into the root of the emacspeak repository and
run the following commands

make clean
make config
make

This will configure and build the emacspeak sources.

Then delete the .emacs file you created and create a directory within
your home directory called .emacs.d e.g.

mkdir ~/.emacs.d

then use a text editor of choice and create a file within that directory
called init.el I use vi for little tasks like this. The vi editor is a
handy editor to be familiar with because you will always find it
installed on a Linux system. However, it has an unusual modal editing
mode which can be confusing at first. Any text editor will work. Some
people like nano e.g.

vi ~/.emacs.d/init.el

In that file, add the following lines

(add-to-list 'load-path (expand-file-name "~/emacspeak/lisp"))
(setenv "DTK_PROGRAM" "espeak")
(setenv "EMACSPEAK_DIR" (expand-file-name "~/emacspeak")
(load-file (expand-file-name "~/emacspeak/lisp/emacspeak-setup.el"))

Save the file and then you should hear Emacspeak speaking when you start
emacs. There is a lot more you can configure and you will want to add
lots more to your init.el file, but to start with, this should be
sufficient.
