VITS with CSMSC
This example contains code used to train a VITS model with Chinese Standard Mandarin Speech Copus.
Dataset
Download and Extract
Download CSMSC from it's Official Website.
Get MFA Result and Extract
We use MFA to get phonemes for VITS, the durations of MFA are not needed here. You can download from here baker_alignment_tone.tar.gz, or train your MFA model reference to mfa example of our repo.
Get Started
Assume the path to the dataset is ~/datasets/BZNSYP
.
Assume the path to the MFA result of CSMSC is ./baker_alignment_tone
.
Run the command below to
- source path.
- preprocess the dataset.
- train the model.
- synthesize wavs.
- synthesize waveform from
metadata.jsonl
. - synthesize waveform from a text file.
- synthesize waveform from
./run.sh
You can choose a range of stages you want to run, or set stage
equal to stop-stage
to use only one stage, for example, running the following command will only preprocess the dataset.
./run.sh --stage 0 --stop-stage 0
Data Preprocessing
./local/preprocess.sh ${conf_path}
When it is done. A dump
folder is created in the current directory. The structure of the dump folder is listed below.
dump
├── dev
│ ├── norm
│ └── raw
├── phone_id_map.txt
├── speaker_id_map.txt
├── test
│ ├── norm
│ └── raw
└── train
├── feats_stats.npy
├── norm
└── raw
The dataset is split into 3 parts, namely train
, dev
, and test
, each of which contains a norm
and raw
subfolder. The raw folder contains wave and linear spectrogram of each utterance, while the norm folder contains normalized ones. The statistics used to normalize features are computed from the training set, which is located in dump/train/feats_stats.npy
.
Also, there is a metadata.jsonl
in each subfolder. It is a table-like file that contains phones, text_lengths, feats, feats_lengths, the path of linear spectrogram features, the path of raw waves, speaker, and the id of each utterance.
Model Training
CUDA_VISIBLE_DEVICES=${gpus} ./local/train.sh ${conf_path} ${train_output_path}
./local/train.sh
calls ${BIN_DIR}/train.py
.
Here's the complete help message.

Pretrained Model
The pretrained model can be downloaded here:
- vits_csmsc_ckpt_1.1.0.zip (add_blank=true)
VITS checkpoint contains files listed below.
vits_csmsc_ckpt_1.1.0
├── default.yaml # default config used to train vitx
├── phone_id_map.txt # phone vocabulary file when training vits
└── snapshot_iter_350000.pdz # model parameters and optimizer states
ps: This ckpt is not good enough, a better result is training
You can use the following scripts to synthesize for ${BIN_DIR}/../sentences.txt
using pretrained VITS.
