Multi-band MelGAN trained on LJSpeech (En)

This repository provides a pretrained Multi-band MelGAN trained on LJSpeech dataset (Eng). 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:

pip install TensorFlowTTS
