[P] Best voice cloning TTS process for realism?

Hello, I am trying to clone my voice as realistically as possible into a TTS model. I am currently looking at using Fastpitch in combination with ChatGLM+lora, as this seems to generally result in realistic results. However, the data preparation and training process for this is fairly tedious and takes a long time. Is there a better method that can achieve a similar level of realism? Thanks!
