YAML Metadata Error: "language" with value "chinese" is not valid. It must be an ISO 639-1, 639-2 or 639-3 code (two/three letters), or a special value like "code", "multilingual". If you want to use BCP-47 identifiers, you can specify them in language_bcp47.

FastSpeech2 trained on Baker (Chinese)

This repository provides a pretrained FastSpeech2 trained on Baker dataset (Ch). For a detail of the model, we encourage you to read more about TensorFlowTTS.

Install TensorFlowTTS

First of all, please install TensorFlowTTS with the following command:
