Thank you for your feedback!!
We're super sorry for the browser version not having screenreader support. It seems to be a very common problem that we weren't able to solve yet. If you have any hints - we would love to get them.
We'll try to export a version for Linux, but we had the impression that Orca doesn't seem to like Godot unfortunately. At least in the test view it simply refused to read anything we added for accessibilty (alternative texts etc.).
With Godot browser version is not yet accessible friendly out of the box. But btzr has been working on an addon for a long time for this: https://github.com/btzr-io/godot-aria
Alternatively, I think the TTS can be used to speak text: https://docs.godotengine.org/en/stable/tutorials/audio/text_to_speech.html#basic...
ORCA works with live regions and buttons, sliders, etc. for me, It reads the accessibility_name or button text. I'm not sure about non-interactive nodes like labels that don't have accessibility mode set. I ended up using a live region to get any screen reader to read out the text I want it to.
