My brltty 6.0 doesn't have the double speech problem but other speech related problems which I hope to get a workarround with a new brltty version. Unfortunately we use Ubuntu 20.04 LTS at work and I couldn't find a ppa with newer Version of brltty so I have to build it myself.

Re: [BRLTTY] Problems when using brltty in the terminal
Hi, I would be intersting to test our accessibility stuff with pipewire which will replace pulseaudio. @Christian: If you don't need pulseaudio switch back to alsa and use libao output driver. Running pulseaudio through dmix has some disadvantages if you want to use usb headsets. Dmix will break Autoswitching of audio output. HTH.

Are the changes in /etc/pulseaudio/default.pa the only necessary changes I have to perform on a standard Debian system, or are there other things I have to do? If yes, I’ll try it on a fresh Debian Bullsey installation. I am curious if the setup is working and if latency is really that big that it might be a problem.

Just let me know if there is is something ready to test and where to get it ;-). Thank you all for your great support and ideas to help me with the setup I have on mind and I’d like to test to have a good working environment for hopefully the next years.

If yes, I’ll try it on a fresh Debian Bullsey installation. I am curious if the setup is working and if latency is really that big that it might be a problem. It's hard for me to answer, as I don't have a Debian installed. If memory serves, you'd have to check the alsa configuration as some settings rely on pulseaudio, which should be avoided. I could install Debian in a VM to check but that won't be soon, as I am pretty busy right now. Meanwhile you could install Slint (in a VM?) and check if the latency is acceptable.

Is what's wanted, when not on a terminal window, > that Orca renders the speech but brltty renders the braille? No. The problem is with non-terminal windows. Brltty's speech driver is still getting content from the atspi2 driver, even if with SCQ_POOR level, and speaks it, in parallel of Orca doing its own speak. The simplest would be to just add an option to make the atspi2 screen driver not always return content, event at poor level, if it's not of the desired type. Another, more complex way would be to add an option to make brltty's speech only emit messages when the screen driver reports having good quality. Another, yet more complex way would be to add to speech dispatcher a notion of overriding priority. Samuel ___ This message was sent via the BRLTTY mailing list.

[quoted lines by Christian Schoepplein on 2021/05/09 at 22:04 +0200] >It would be really cool if you have another idea that could help. The AtSpi2 screen driver used to have a focus parameter which could contrain it to terminal windows. We dropped that parameter when brlapi priorities were introduced because that let tee AtSpi2 screen driver drop its content quality when not on a terminal window, thus giving brlapi preference to Orca. We didn't consider the possibility that Orca wouldn't be using that brltty's brlapi interface.
