  # Multi-band MelGAN trained on Synpaflex (Fr)
  This repository provides a pretrained [Multi-band MelGAN](https://arxiv.org/abs/2005.05106) trained on Synpaflex dataset (French). 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-synpaflex-fr")
  tacotron2 = TFAutoModel.from_pretrained("tensorspeech/tts-tacotron2-synpaflex-fr")
  mb_melgan = TFAutoModel.from_pretrained("tensorspeech/tts-mb_melgan-synpaflex-fr")
  
  text = "Oh, je voudrais tant que tu te souviennes Des jours heureux quand nous étions amis"
  
  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")
  ```
