@spacepup Which one? The formant synthesizer one, or the BestSpeech decompilation project since I'm actually working on both right now.
As far as the formant synthesizer goes, it started out as a freelance project meant to be coded in Rust. In recent months, I've been thinking about getting it over to C as well.
My client has been kinda on and off lately. If things don't pan out with him, I'm going full on in on the C version since per contract I can't just put out the Rust code. That way people can easily create SAPI adapters for it when it's all complete.
@spacepup @BorrisInABox Indeed. I came up with an efficient method of generating Fujisaki like pitch contours.
In fact, I shared the python prototype of the pitch model with Tamas a while back.
