+# Multi-band MelGAN trained on Baker (Ch)
+This repository provides a pretrained [Multi-band MelGAN](https://arxiv.org/abs/2005.05106) trained on Baker dataset (ch). For a detail of the model, we encourage you to read more about
+[TensorFlowTTS](https://github.com/TensorSpeech/TensorFlowTTS). 
+
+
+## Install TensorFlowTTS
+First of all, please install TensorFlowTTS with the following command:
+```
+pip install TensorFlowTTS
+```
+
+### Converting your Text to Wav
+```python
+import soundfile as sf
+import numpy as np
+
+import tensorflow as tf
+
+from tensorflow_tts.inference import AutoProcessor
+from tensorflow_tts.inference import TFAutoModel
+
+processor = AutoProcessor.from_pretrained("tensorspeech/tts-tacotron2-baker-ch")
+tacotron2 = TFAutoModel.from_pretrained("tensorspeech/tts-tacotron2-baker-ch")
+mb_melgan = TFAutoModel.from_pretrained("tensorspeech/tts-mb_melgan-baker-ch")
+
+text = "这是一个开源的端到端中文语音合成系统"
+
+input_ids = processor.text_to_sequence(text)
+
+# tacotron2 inference (text-to-mel)
+decoder_output, mel_outputs, stop_token_prediction, alignment_history = tacotron2.inference(
+    input_ids=tf.expand_dims(tf.convert_to_tensor(input_ids, dtype=tf.int32), 0),
+    input_lengths=tf.convert_to_tensor([len(input_ids)], tf.int32),
+    speaker_ids=tf.convert_to_tensor([0], dtype=tf.int32),
+)
+
+# melgan inference (mel-to-wav)
+audio = mb_melgan.inference(mel_outputs)[0, :, 0]
+
+# save to file
+sf.write('./audio.wav', audio, 22050, "PCM_16")
