Last time I was successful in making Orca work, it used its own speech output separate from BRLTTY's with ALSA or PulseAudio doing the audio multiplexing/mixing. I try to stay in the text console as much as possible though, so I'm not a good reference about Orca usage. Nicolas___ This message was sent via the BRLTTY mailing list.

Re: [BRLTTY] Making brltty speak
Many thanks for your clarifications, Nicolas. I do believe that what you are describing is the best way to go, i.e. having a good integration between speech and braille. Is it pulseaudio that you use to output speech? Does it run as root on your system? If so, does speech-dispatcher run as root as well, assuming that's what you are using to deal with speech? Do you also have applications running as your own user and connecting to speech-dispatcher, like orca? Best wishes, Sébastien. ___ This message was sent via the BRLTTY mailing list.

Speech is controlled by brltty. The integration of both is much better this way. I can move the braille window around and have its content spoken automatically. I can control speech with the braille terminal's keys, I can have the whole screen read out loud with the braille window following along, etc. Nicolas___ This message was sent via the BRLTTY mailing list.

Re: [BRLTTY] Making brltty speak
Hi Nicolas and many thanks for your testimonial! IS it brltty that you use to control the speech synthesis system, or do you use two different screen readers, one for speech and brltty for braille?

I've been using braille and speech simultaneously since the day I couldn't use a screen monitor any longer. Speech output is much faster than one can read braille, and braille is unbeatable when text layout and special characters are in play. So using both in parallel is the ultimate productivity setup as far as I'm concerned. Nicolas___ This message was sent via the BRLTTY mailing list.

Well as far as I understand it, it still uses Pulse Audio in a way because, at the moment, speech-dispatcher does not implement a pipewire output method so one has to install pipewire-pulse (on Debian) so that pipewire emulates a pulseaudio interface speech-dispatcher can connect to. Or am I missing something? > One of the many advantages of using a braille display is that it allows you > to interact with your system without working audio. I know that, of course.

Whatever you do, switching *away* from PulseAudio is likely the right solution.

Hello Halim and many thanks to all for your help. It seems the cleanest solution is to switch from PulseAudo to PipeWire so I'll have to continue experimenting with that.

Many thanks for your response Halim. I would really like to be able not to use pulse audio, but unfortunately I am using GUI so I am not sure this is really an option.

Re: [BRLTTY] Making brltty speak
Hi again, if you're using a desktop as well you can reconfigure pulseaudio to store it's socket in /tmp. That way you can access one running pulseaudio from diferent user accounts. Another dirty hack is to set dmix for pulseaudio. That way it can not block the audio device and speechd can use alsa at the same time with pulseaudio. To get this working edit /etc/pulse/default.pa and search the line #load-module module-alsa-sink uncomment that line by remove the # and change it to load-module module-alsa-sink device=dmix a 3rd method: set a symlink so that user root can use speech-dispatcher of the desktop user. 1. logon as root 2. ln -sf /run/user/1000/speech-dispatcher/speechd.sock ~/.cache/speech-dispatcher/speechd.sock In Ubuntu 20.04 LTS> I use the last described setup.

Hi Sébastien, if you want to use only plain consoles set audiooutputmethod in speechd.conf to EG. libao and uninstall pulseaudio. BR. Halim ___ This message was sent via the BRLTTY mailing list.

[BRLTTY] Making brltty speak
Dear all, I'd like to try using brltty with speech-dispatcher. Currently, it seems my system is configured to have each user run its own speech-dispatcher that uses a per-user instance of pulse-audio for output. Given that brltty runs as root, is it required that speech-dispatcher and pulseaudio also run as root? If somebody has hints about how to set this up on Debian I'd be interested.
