Writing documentation for piper TTS intigration

[danielw97]

Hi everyone,
I see from looking at the git log, that there was support for piper tts added in 2023 by @mush42 and if I'm reading things right finalized in commit e66a61d
However, I can't find any documentation or discussions around this at all.
Is the process of updating the documentation on the roadmap, or is the feature itself still in progress?
If it is complete, I would be willing to help write some English documentation assuming this isn't in progress already.
I'm currently looking into the code to test the feature out, but have used piper in other projects so am already familiar with the platform.
Hth a bit,

Daniel
