Hi, I've been trying to get Emacspeak working on my mobile phone, which is running LineageOS 17.1 (based on Android 10). So far, I've tried a couple of things, but neither has quite worked. First, I tried installing Emacspeak on debian-buster from proot-distro in Termux. Unfortunately, it's silent, and running espeak on its own results in a long list of errors, starting with > ALSA lib confmisc.c:767:(parse_card) cannot find card '0' so I guess Termux's proot-distro isn't giving Debian access to the audio. For another attempt, I tried building Emacspeak directly in Termux. This required building TclX, too, which seemed to work, but when I tried running `./servers/espeak` it gave these errors > couldn't load file > "/data/data/com.termux/files/usr/lib/tclx8.4/libtclx8.4.so": dlopen > failed: cannot locate symbol "rresvport" referenced by > "/data/data/com.termux/files/usr/lib/tclx8.4/libtclx8.4.so"... > while executing > "load /data/data/com.termux/files/usr/lib/tclx8.4/libtclx8.4.so Tclx" > ("package ifneeded Tclx 8.4" script) > invoked from within > "package require Tclx" > (file "./servers/espeak" line 37) so I guess TclX relies on rresvport, whatever that is, and Termux doesn't provide it. Does anyone have any clues about how I might be able to get Emacspeak running on my phone? Thanks, Tim <>< _______________________________________________ Emacspeak mailing list -- emacspeak(a)emacspeak.org To unsubscribe send an email to emacspeak-leave(a)emacspeak.org

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.

I'm using Espeak. I tend to avoid non‒open source software, and Espeak was 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!

After a long pause, I finally got back to this, and with the help of the log-espeak speech server, I found the solution to the silent lines in tables was as simple as: sudo apt install alsa-utils That solution also means I don't have to change emacspeak-auditory-icon-function from its default value. Now that I have a fully usable (if somewhat convoluted) way to run Emacspeak on Android, I've drafted an org file (see attached) that I hope will be useful for others. Because I arrived at my configuration via a lot of experimentation, I'm not completely certain that I've described everything necessary in the org file, so I'd appreciate someone starting from scratch (preferably without either Termux or UserLAnd already installed), and testing whether my instructions are sufficient to get Emacspeak working on their Android device.

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.
