/Well, maybe I've just seen it by the big number of pulls here in this repo, so maybe I'll ask and even tell about this news:
Is this Piper TTS repo stop developing due to the new Piper1-GPL repo that uses eSpeakNG as it's phonemizer? As I remember, the official, main PiperTTS repo is using a MIT license. I believe this is the branch that maybe new phonemizers will get supported. Then the newest GPL branch? fork? that uses eSpeakNG as it's phonemizer and even? text. Maybe the Sonata devs had seen the changes? I'll tell them.
Edit. Sent a messaje to the Sonata dev. Hope I get some answers or that I had understood.
