**Response to @Suhail:**
As soon as they encode intonation and remove the need to be on beat perfectly, it'll open a wide range of content that can be made by anyone. Choose lyrics, badly sing, get vocal
The main tell for AI vocals (I've been watching closely) is generally the voice lacks a breathiness.
