My Voice Assistant Preview Edition seems to be working intermittently. The actual assistant is fine, I can type what is the weather to it in the text chat but when it comes to the home assistant preview edition it seems there are some errors when piper processes the text to speech voice. (I’m running on a pi4).
As far as i can see, whisper, open wake word seem fine so piper may be the issue. I know python as a language but not knowing piper i can’t debug myself and was hoping someone else could help me as my setup is as basic as it comes.
Here is the main error log, piper log and whisper log.
