Singing-Voice-Conversion-with-conditional-VAW-GAN

This is the implementation of the paper "VAW-GAN for Singing Voice Conversion with Non-parallel Training Data". This work is submitted to APSIPA 2020.

This work is about ...

In this work, we propose a singing voice conversion framework that is based on VAW-GAN [1]. We train an encoder to disentangle singer identity and singing prosody (F0 contour) from phonetic content. By conditioning on singer identity and F0, the decoder generates output spectral features with unseen target singer identity, and improves the F0 rendering. Our proposed method can significantly reduce the spectrum distortion and improve the converted singing quality. For more details, please refer to our paper.

Getting Started

Prerequisites

• Ubuntu 16.04
• Python 3.6
  • Tensorflow-gpu 1.5.0
  • PyWorld
  • librosa
  • soundfile
  • numpy 1.14.0
  • sklearn
  • glob
  • scipy

Database

In this work, we use NUS Sung and Spoken Lyrics Corpus (NUS-48E corpus) [2], which consists of the sung and spoken lyrics of 48 English songs by 12 professional singers. We choose two male singers and one female singers for all the experiments. For each singer, 6 songs are used for training and evaluation.

Please make sure your singing data is saved in the following structure and change the path in .json file:
"./data_multi/wav/training_set/SOURCE_SINGERID/xxxx.wav"
"./data_multi/wav/evaluation_set/TARGET_SINGERID/xxxx.wav"

Usage

1. Activate your virtual enviroment.

source activate [your env]

2. Extract features from raw audio.

$ python analyzer.py 

3. Analyze features.

$ python build.py 

4. Train the network.

$ python main-vawgan.py 

5. Conversion.

$ python convert-vawgan.py --src 'SOURCE_SINGER_ID' --trg 'TARGET_SINGER_ID' --checkpoint './logdir/train/PLEASE_SPECIFY_YOUR_CHECKPOINT/model.ckpt-46860'
