Pied wipes speech dispatcher config

[C-Loftus]

Thank you for your work on this repo. I was hoping to use it with the Orca screen reader but unfortunately in my testing I am finding that upon installing a voice it wipes the speech dispatcher config located at ~/.config/speech-dispatcher. This is a problem for non-visual users since speech dispatcher is tricky to configure and when the config is wiped, all the synthesizers need to be reconfigured. Very often a user will want to switch between synthesizers quickly and just having one like piper installed at a time makes this a longer process to switch.

I tried to solve this myself but couldn't figure it out given some local issues building flatpak and my unfamiliarity with dart. Any tips would be much appreciated. I presume this is a simple fix just with path issues and would help a lot of visually impaired folks!

This is the cause of #25 , and prevents users from using other voices with other client apps using speech dispatcher

The screenshot below shows the config folder before running pied. Note how there are many modules and a full speechd.conf file with many options inside

However after running pied and selecting a voice from the GUI all of these modules are wiped. Its possible that this is the result of a files being moved or something analogous. Also once the config is applied the speechd.conf file becomes just the pied template and no longer contains any of the global settings the user had before

I saw that there is an existing discussion about a way to revert the install by moving the config back, but ideally, unless I'm missing something, can't you just append to the speech dispatcher config and not mutate / move anything else?

(I don't see a reason for overwriting everything, if pied wants to update piper.conf, it can limit itself to that. Actually, the tendency is to just not have to modify a .conf file, and just auto-detect everything and let users choose the voice inside e.g. the orca configuration panel)

I think to make pied work one needs both a piper.conf and some custom configs in speechd.conf. It for sure needs to add 'AddModule "piper-tts-generic" "sd_generic" "piper.conf"' to speechd.conf. Perhaps a default that could be explored could be creating a piper.conf (and retaining other voice configs). In regards to speechd.conf I'm not sure how non-intrusively one can change the config, it might be simplest to just backup the file and replace it with the default pied config. The pied config does include 'Include "clients/*.conf"' which seems to point that it could work with prior voice configs.

No.

Since a long time already speech-dispatcher just loads by default all modules it sees, so that users don't have to modify a file to be able to use a module that they have just installed. All an installer should need to do is to just install piper.conf and send SIGHUP to make speech-dispatcher look again and load the new module.

It seems like you know a lot more about speech dispatcher than I do. Do you mind if I ask a few questions about the config. I am working on mapping out a less destructive backup solution for pied (probably just backing up piper.conf if it exists and my current idea was to also just backup speechd.conf but are you saying that is not necessary?). What about the "DefaultModule" option in speechd.conf Does it make sense for pied to set that to piper (for me it did as I wanted to use piper voices). I am a bit cautious about speechd.conf configs. Would it be reasonable for pied to backup speechd.conf to something like speechd.conf.bak and then search if DefaultModule is set, change it to pied, and then nothing else is necessary?

If the change is really non-intrusive, it's not really necessary.

Yes, it does make sense, that don't prevent other modules from appearing in orca etc.
