Hi,
The value of emacspeak-auditory-icon-function was emacspeak-serve-auditory-
icon both on my laptop, where it worked, and on my phone, where it didn't.
Changing it to emacspeak-play-auditory-icon gives me all the more complex
auditory icons on my phone, and, curiously, sometimes (but not always)
doubles auditory icons on my laptop.
However, even with the auditory icons working on my phone, I still don't
hear the text of the table of subsections at
https://www.gnu.org/software/emacs/manual/html_node/gnus/Using-IMAP.html
unless I read it character by character. I'm starting to think that this may be because it's a table, rather than because it's got links in it, but I haven't thought of any handy tables without links I can test it on. I also get silence when reading the tabulated lines of an apropos window, which have a function name in the left-hand column and a keyboard shortcut in the right-hand column, but even there, the function names act as links.
So maybe there are two things going on here: emacspeak-serve-auditory-icon
not working in Debian in UserLAnd on Android, and the text of tables not
being read aloud in the same environment. But maybe they have the same
underlying cause? I don't know.
All the best,
Tim

Hi,I now have a bluetooth keyboard for my phone. I've found that I get
much
better audio by running PulseAudio in Termux and sending the audio from
UserLAnd to Termux via PulseAudio's native TCP module. (I tried a fully
within-Termux solution using proot-distro, but there seemed to be a lot
of
leakage of (for example) Termux's own Emacs installation into the PRoot
environment, whether or not its own Emacs was installed; it just got too
confusing.)
Before I carefully document my setup, though, I've discovered another
problem. In fact, I think it's a problem I encountered before, but
misunderstood and mischaracterized. I thought that upgrading to Emacs
27.1
and Emacspeak 54.0 had fixed it, but I think I just misunderstood the
problem.
What I'm observing now (with those versions, and espeak 1.49.2 from
Debian
10's main repository) is that on Android, auditory icons that are simple
tones (like that for a blank line) are working. But icons that are more
complex sounds (like what you hear when moving onto one of the lines in
the
bulleted list of subsections at
https://www.gnu.org/software/emacs/manual/html_node/gnus/Using-IMAP.html
for
example) are silent, and can cause the entire utterance to be
silent. Even
moving forward word by word on one of those lines results in silence,
though
moving forward character by character works fine. (The links to
chapters of
the Emacspeak info manual, as bundled in Emacspeak, rather than as found
on
the web, are audible, even when I try to induce an auditory icon by
pressing
tab to move to the next link, though the auditory icon itself isn't
audible.)
This is the case despite the fact that I can play arbitrary wav files
from
the command line on my phone, and despite the fact that the same
versions of
the same programs work fine on my laptop (which is also running Debian
10).
Does anyone have any clues about what might be going wrong here?
All the best,
Tim

Espeak

conveniently in Debian's main repository, so I chose that one.
I might not get around to fine-tuning my Emacspeak-on-Android setup
unless
and until I get a physical keyboard talking to my phone, so if someone
else
wants to take up the baton in the meantime, I won't object.
Also, I have no experience writing org files, but orgmode.org looks
interesting (similar to MarkDown, but more powerful?), so learning
that
might get added to my Emacs-learning curve at some point!

Very Nice!
I suspect tweaking buffer-size will give you most bang for the buck;
Are
you using Outloud or Espeak?
Once you get this tuned to your liking, I'd request you write it up
as a
simple org file and post it somewhere; I'd also like to include it
in
the emacspeak distribution when the write-up is ready.Hi,
Thank you all for your replies. Inspired partly by them, partly
by an
answer I received on the #termux IRC channel, and partly by my own
stubbornness, I searched for ways to get the audio out of
something
like
UserLAnd or a Termux PRoot environment.
And I succeeded! With auditory icons, and everything!
The trick is to use PulseAudio to stream the audio out of UserLAnd
(or
PRoot). In particular, I installed pulseaudio in UserLAnd's
Debian
environment and added this line to the bottom of
/etc/pulse/default.pa
there:
load-module module-simple-protocol-tcp source=auto_null.monitor
record=true
port=54713 listen=127.0.0.1
(Apologies for any spurious linebreaks added by my email program;
it
should
be a single line.) Then with PulseAudio started, I connected to
the
stream
from SimpleProtocolPlayer NG
https://f-droid.org/packages/fr.jakse.raphael.simpleprotocolplayer
and started Emacspeak in UserLAnd. The sound is a bit choppy, but
it's
a
proof of concept, at least. I haven't yet thoroughly tested
whether
the
audio output would be improved by different settings like:
* a different buffer size in Simple Protocol Player NG,
* a different sample rate,
* streaming the audio to Termux instead of Simple Protocol Player
NG,
* running Emacspeak in Termux's PRoot instead of UserLAnd,
* streaming over a Unix special file instead of TCP,
* and so on.
The main web pages I drew on for my understanding were:
* https://android.stackexchange.com/a/205629
* https://kaytat.com/blog/?page_id=301
* https://github.com/CypherpunkArmory/UserLAnd/issues/371
They often assume a visual desktop, but this isn't necessary; I
can
run
Emacspeak in emacs-nox in UserLAnd, without any visual desktop
installed.
I did notice that it didn't fully work with Debian buster's
emacspeak
package (version 49.0) in Emacs 26.1; the output seemed to be
silent
for
some utterances, perhaps triggered by auditory icons or voice
locking
or
both. But switching to Emacs 27.1 (from buster-backports) and
compiling
Emacspeak 53.0 from source in UserLAnd solved that problem.
Now, to complete the eyes-free experience on my mobile phone, I
need a
physical keyboard I can connect to it, preferably without wires,
so I
don't
tie myself up in cords. But before investing in that, perhaps I
should
figure out whether, in the long run, Emacspeak will make me more
productive
than a visual desktop, rather than less. At the moment, I'm
finding a
fairly steep Emacs-learning curve (mostly keybindings), but I'm
still
hopeful that it will be worth it.
I hope this is helpful and encouraging.
All the best,
Tim

1. Speech Server: Voice changes are hard to implement using the
current
setup, but feasable;
A. Look up Google TTS documentation, provides pitch change as
the
only control from memory.
B. Copy plain-voices.el to android-voices.el, then follow
the
code
and update it to generate the pitch control changes.
C. Finally add the necessary clause in dtk-speak.el to
load
android-voices.el if synthesis engine is Android.
2. Auditory Icons, Again doable, but you'd have to
write
some Java code in the Android speech server to
play
sounds, you'll likely need to package over the
sound
files and copy them to the Android side.
