After seeing the success of the Chinese special version, we also trained the Japanese special version. Update log: 1.Delete Chinese and English support. 2.Merge Pull Request(#312 ), which fixed an error existed in previous Japanese g2p. (Thanks @litagin02 ) 3.We increased Japanese training data several times. Now up to ~800h single language. 4.Thrown away DurationDiscriminator, which often lead to training unstable. 5.Changed the emotion VectorQuantize, try to have a larger codebook_size but smaller codebook_dim to help increase the usage of codebook. By the hand, We also fix the loss_commit,add it to backward. The base model could be found at huggingface. Bert-VITS2 development team yours truly
