Usage

The directiory for experiment is located in exp.

0. Install Rye

Please follow the installation instructions here.

After that, set up the project by running the following command:

$ rye sync

1. Preprocessing (00_preprocess)

  1. Split dat to train/valid
  2. Extract F0 with Harvest

Default config is located in src/vocoders/bin/conf/path/dummy.yaml, so if you run with original dataset, please change the path config file.
Current system supports single-speaker or universal vocoder, and it is assumed that the audio files to be used are placed in the wav_dir.
Additionally, the audio files are expected to be 1 channel, 16-bit, 24kHz in default settings.
If you wanna train your own dataset, change the parameters of src/vocoders/bin/conf/mel/default.yaml to your settings.

Then run the preprocess script

$ cd /path/to/vocoders/exp/00_preprocess

$ ./run.sh

2. Training

Move to the 01_traindirectory in prepared experiment directories(e.g. exp/01_hifigan) and execute the following command.

# e.g. : `01_hifigan`
$ cd /path/to/vocoders/exp/01_hifigan/01_train

$ ./run.sh

3. Synthesis

Move to the 02_syn directory and execute the following command.
The default checkpoint file is set as 01_train/out/ckpt/last.ckpt.
In the process, validation data is synthesized and evaluated.

# e.g. : `01_hifigan`
$ cd /path/to/vocoders/exp/01_hifigan/02_syn

$ ./run.sh
