@[url=https://ani.social/u/TheMightyCat]TheMightyCat[/url] Oh yes, thanks for your interest and a nice comment.

A somewhat simplified explanation of linux accessibility stack from an advanced user (not developer) looks like this:

Standard linux screen reader running alongside graphical desktop environments such as gnome or KDE is called orca. It uses a dependency called at-spi2-core for delivering and interpreting accessibility events from different toolkits such as GTK4, QT6 and similar.

Thus at-spi2-core has clients on both the sides. Orca usually consumes events and GUI toolkits and other standalone apps generate them.

For the full picture there are apps that communicate to at-spi2-core directly to provide its accessibility for example web browsers (Firefox, Chromium and webkit-gtk) and libreoffice are doing this.

The fact screen reader is interpreting accessibility events delivered to it through at-spi2-core is a nice thing and it's a huge part of the puzzle however screen reader has more functionality than dealing with the stream of accessibility events.

For example screen reader needs to be able to review the content by words, by lines and provide different navigation actions.

For that it needs to react to user key presses.

On wayland reacting to keypresses without having a control focused is a security risk thus a protocol extension has been developed which allows screen reader to ask at-spi2-core to coordinate grabbing the keys with the compositor. I don't fully understand this part so it may be a very rough explanation. However it's key point to understand that for touch screen operated device it's not enough to read what has happened in response to some touch screen gestures. We need an ability to review the screen content before executing actions. On different platforms such as android, IOS or Windows it's implemented in a way so touch interaction model works a bit differently when screen reader is running. This is not yet implemented for linux no matter which form factor.

Technically speaking if I would have an USB keyboard connected to the phone I would certainly be able to use parts of its graphical interface but that would not be practical enough.

Please excuse me for commenting on your announcement thread even adding such a long attempt at explaining my situation. I do really appreciate all the work and advancements you are releasing to the public.

It's just that I am partially saddened by the fact I can't experience this linux mobile movement on my own.

It's a pity screen reader accessibility is not yet a thing on mobile linux at least I can't find someone making great progress with that.

@[url=https://toot.cafe/users/matt]Matt Campbell[/url] It's still trained using the same stack like piper and runs through onnx runtime but @[url=https://grapheneos.social/users/GrapheneOS]GrapheneOS[/url] people have forked matcha TTS and even managed to write their own phonemizer for english so it no longer needs espeak. They are hoping to improve the performance of their speech services android app using it. I think it's worth looking into and taking some good use of.

@[url=https://grapheneos.social/users/GrapheneOS]GrapheneOS[/url] I'm looking if I might be able to add support for different languages in the future. I see you've written a phonemizer doing the g2p as a part of the app. However training is done on a computer running your improved matcha TTS. While training what phonemizer were you using? Matcha's fork of Misaki or something else? I will be looking more into it, I'm also too excited about it right now.

@[url=https://fosstodon.org/users/treefit]treefit[/url] Hmm, I can't get it to work no matter what I'm trying.
When I have started my $XDG_DATA_HOME environment variable was not set meaning it should fall back to the default ~/.local/share as per the XDG spec.
I have added it into my /etc/profile.d/0000-xdgdirs.sh file, rebooted, rebuilt delta-tauri with its dependencies but I'm still getting the same error.
Printing $XDG_DATA_HOME now gives me /home/myusername/.local/share, the directory does exist with 0755 permissions and it contains nested directories created by other apps on my system.
Is there a way to find out what the file path and the file name of the resulting log file should be?

Dear @[url=https://fosstodon.org/users/treefit]treefit[/url]
I am trying to build #[url=https://fedi.ml/search?tag=deltatauri]deltatauri[/url] on ArchLinux and I have issues running the resulting binary.
Upon launch it prints:
[code]
Failed to setup app: error encountered during setup hook: current logfile does not exist

[/code]
I am removing all the targets except of deb, then building like normal and moving files into place.
[code]
sed -i 's/"targets"\: "all"/"targets"\: ["deb"]/' packages/target-tauri/src-tauri/tauri.conf.json5
pnpm install
cd packages/target-tauri

[/code]
Can you please think of where I am failing likelly? I can run binaries built elsewhere so I guess webkit-gtk and other dependencies are installed.

Yesterday I was running newton all day long. And all these tests were made with it. Today I am back to stable versions so far as I had to deal with inaccessible website about a hour ago.

I don't want to sound rude in any way but if I was able to do a little recap I can point out these issues related to newton prototype:<li>I am afraid there might be some invisible content present when using flat review.</li><li>Expanded or collapsed state is not passed through to orca (tested with fractal room list)</li><li>When running GTK4 from the accesskit branch, there are issues selecting GTK2 and electron based apps in the alt+tab window chooser.</li>

These are the things I am aware of.
If you need me to test something more thoroughly, please do let me know and I will try to do my best.

Hmmm, so it's even more complicated than I was imagining. I think what is done within the nautilus files view is not entirely right either. At the other hand projects with good a11y reputation such as thunderbird are doing it too. Thunderbird has aria-label on its message list items too. When looking at nautilus window with flat review or object navigation all the textual information is there. If using it the way it has been designed just using standard navigation keys such as arrow keys it's looking very poor.

Thank you again, I've great news this time as well. After updating the newton_atspi_compat package the flat review with newton is working fine. With nautilus it started to work immediatelly when I've restarted orca with the updated newton_atspi_compat package in place. With fractal it started to work after restarting fractal.

Also I must say I have found my-self reporting a strange thing yesterday. I have mentioned I have tried gedit as a part of this testing however now I have realized gedit is a GTK3 app not GTK4.
When looking at gedit main window I can use orca's flat review to explore its toolbar including moving the mouse pointer and synthesizing mouse clicks. When doing the same thing with GTK4 apps such as nautilus or fractal the flat review is working great but emulating the mouse is not.

Excuse me for this mistake. I got it wrong.

And just now I have noticed another thing. I wanted to verify the mouse emulation features by running gtk-demo app which is GTK3 app too. I have tried to run gtk-demo from the gnome-terminal. As it has started I have noticed orca briefly reporting GTK demo however I can't focus its window. When holding down the alt key and pressing the tab key to cycle through the open windows, I can hear GTK Demo is part of the window switcher but when releasing both the keys that window is never brought to the foreground. When expanding activities from the gnome top pannel I can't locate GTK demo either. The very same thing has happened to me with an electron based app called losslesscut but originally I have assumed that was a momentarily thing related to electron but now when seeing it for the second time with a different toolkit I am wondering if this might be related to the mutter changes.

I am sorry for mentioning too many things. For some of these I am really unsure so if it's not relevant please ignore those parts.

I apologize for the delay.

Good news first:<li>text review and text selection for GTK labels is now working on both atspi and accesskit respectivelly. Huge thanks!</li><li>Restarting orca while GTK4 app such as nautilus, gnome-calculator or fractal is in the foreground is now safe. I see no more exceptions when releasing keygrabs on exit.</li><li>This is true from the moment I have started testing this yesterday I have just forgotten to mention it. When key echo is enabled in orca with newton it correctly handles accented non ascii characters while typing. I have tested web content in firefox and chromium, gnome-terminal, libreoffice, gedit, nautilus and fractal.</li>

And now the rest:<li>After todays orca update flat review now just displays window title for me for example name of the folder that is opened in nautilus. I think I have updated everything correctly but I can double check it later today.</li><li>Reporting expanded / collapsed state is really an accesskit integration issue I am afraid as switching to atspi on the same GTK4 version I am getting these reported fine.</li><li>Before starting this yesterday I was using GTK4 4.14.4 as packaged in archlinux. That version has some positive and some negative changes as well than the version you have started with while integrating accesskit. For example the thing with conversation history in fractal I have mentioned in my previous report is broken with GTK4 4.14.4 as packaged in arch linux but it's working fine with both atspi and accesskit when using your branch. Thus I think it's not related to your work. At the other hand in fractal there is a message composer which has some buttons that inwoke a popup menu such as more options. When that menu is dismissed fractal freezes with atspi and accesskit when using GTK4 built from your branch and with the arch linux packaged GTK4 version it's working fine.</li>
