SoftVC VITS Singing Voice Conversion
In the field of Singing Voice Conversion, there is not only one project, SoVitsSvc, but also many other projects, which will not be listed here. The project was officially discontinued for maintenance and Archived. However, there are still other enthusiasts who have created their own branches and continue to maintain the SoVitsSvc project (still unrelated to SvcDevelopTeam and the repository maintainers) and have made some big changes to it for you to find out for yourself.
✨ A fork with a greatly improved interface: 34j/so-vits-svc-fork
✨ A client supports real-time conversion: w-okada/voice-changer
This project is fundamentally different from Vits. Vits is TTS and this project is SVC. TTS cannot be carried out in this project, and Vits cannot carry out SVC, and the two project models are not universal
Announcement
The project was developed to allow the developers' favorite anime characters to sing, Anything involving real people is a departure from the intent of the developer.

🆕 Update!
Updated the 4.0-v2 model, the entire process is the same as 4.0. Compared to 4.0, there is some improvement in certain scenarios, but there are also some cases where it has regressed. Please refer to the 4.0-v2 branch for more information.
📝 4.0 Feature list of branches
Branch | Feature | whether compatible with the main branch model |
---|---|---|
4.0 | main branch | - |
4.0v2 | The VISinger2 model is used | incompatibility |
4.0-Vec768-Layer12 | The feature input is the Layer 12 Transformer output of the Content Vec | Compatible after the configuration file is modified |
📝 Model Introduction
The singing voice conversion model uses SoftVC content encoder to extract source audio speech features, then the vectors are directly fed into VITS instead of converting to a text based intermediate; thus the pitch and intonations are conserved. Additionally, the vocoder is changed to NSF HiFiGAN to solve the problem of sound interruption.
🆕 4.0-Vec768-Layer12 Version Update Content
- Feature input is changed to Content Vec Transformer output of 12 layer, the branch is not compatible with 4.0 model
🆕 Questions about compatibility with the main branch model
- You can support the main branch model by modifying the config.json of the main branch model, adding the speech_encoder field to the Model field of config.json, see below for details
"model": {
.........
"ssl_dim": 768,
"n_speakers": 200,
"speech_encoder":"vec256l9"
}

🛠️ Preprocessing
0. Slice audio
Slice to 5s - 15s
, a bit longer is no problem. Too long may lead to torch.cuda.OutOfMemoryError
during training or even pre-processing.
By using audio-slicer-GUI or audio-slicer-CLI
In general, only the Minimum Interval
needs to be adjusted. For statement audio it usually remains default. For singing audio it can be adjusted to 100
or even 50
.
After slicing, delete audio that is too long and too short.
1. Resample to 44100Hz and mono
python resample.py
2. Automatically split the dataset into training and validation sets, and generate configuration files.
python preprocess_flist_config.py --speech_encoder vec768l12
speech_encoder has three choices
vec768l12
vec256l9
hubertsoft
If the speech_encoder argument is omitted, the default value is vec768l12
3. Generate hubert and f0
python preprocess_hubert_f0.py --f0_predictor dio
f0_predictor has four options
crepe
dio
pm
harvest
If the training set is too noisy, use crepe to handle f0
If the f0_predictor parameter is omitted, the default value is dio
After completing the above steps, the dataset directory will contain the preprocessed data, and the dataset_raw folder can be deleted.
You can modify some parameters in the generated config.json
-
keep_ckpts
: Keep the lastkeep_ckpts
models during training. Set to0
will keep them all. Default is3
. -
all_in_mem
: Load all dataset to RAM. It can be enabled when the disk IO of some platforms is too low and the system memory is much larger than your dataset.
🏋️♀️ Training
python train.py -c configs/config.json -m 44k
🤖 Inference
# Example
python inference_main.py -m "logs/44k/G_30400.pth" -c "configs/config.json" -n "君の知らない物語-src.wav" -t 0 -s "nen"
Required parameters:
-m
|--model_path
: path to the model.-c
|--config_path
: path to the configuration file.-n
|--clean_names
: a list of wav file names located in the raw folder.-t
|--trans
: pitch adjustment, supports positive and negative (semitone) values.-s
|--spk_list
: target speaker name for synthesis.-cl
|--clip
: voice forced slicing, set to 0 to turn off(default), duration in seconds.
Optional parameters: see the next section
-lg
|--linear_gradient
: The cross fade length of two audio slices in seconds. If there is a discontinuous voice after forced slicing, you can adjust this value. Otherwise, it is recommended to use the default value of 0.-f0p
|--f0_predictor
: Select F0 predictor, can select crepe,pm,dio,harvest, default pm(note: crepe is original F0 meaning pooling)-a
|--auto_predict_f0
: automatic pitch prediction for voice conversion, do not enable this when converting songs as it can cause serious pitch issues.-cm
|--cluster_model_path
: path to the clustering model, fill in any value if clustering is not trained.-cr
|--cluster_infer_ratio
: proportion of the clustering solution, range 0-1, fill in 0 if the clustering model is not trained.-eh
|--enhance
: Whether to use NSF_HIFIGAN enhancer, this option has certain effect on sound quality enhancement for some models with few training sets, but has negative effect on well-trained models, so it is turned off by default.
🤔 Optional Settings
If the results from the previous section are satisfactory, or if you didn't understand what is being discussed in the following section, you can skip it, and it won't affect the model usage. (These optional settings have a relatively small impact, and they may have some effect on certain specific data, but in most cases, the difference may not be noticeable.)
Automatic f0 prediction
During the 4.0 model training, an f0 predictor is also trained, which can be used for automatic pitch prediction during voice conversion. However, if the effect is not good, manual pitch prediction can be used instead. But please do not enable this feature when converting singing voice as it may cause serious pitch shifting!
- Set
auto_predict_f0
to true in inference_main.
Cluster-based timbre leakage control
Introduction: The clustering scheme can reduce timbre leakage and make the trained model sound more like the target's timbre (although this effect is not very obvious), but using clustering alone will lower the model's clarity (the model may sound unclear). Therefore, this model adopts a fusion method to linearly control the proportion of clustering and non-clustering schemes. In other words, you can manually adjust the ratio between "sounding like the target's timbre" and "being clear and articulate" to find a suitable trade-off point.
The existing steps before clustering do not need to be changed. All you need to do is to train an additional clustering model, which has a relatively low training cost.
- Training process:
- Train on a machine with good CPU performance. According to my experience, it takes about 4 minutes to train each speaker on a Tencent Cloud machine with 6-core CPU.
- Execute
python cluster/train_cluster.py
. The output model will be saved inlogs/44k/kmeans_10000.pt
.
- Inference process:
- Specify
cluster_model_path
ininference_main.py
. - Specify
cluster_infer_ratio
ininference_main.py
, where0
means not using clustering at all,1
means only using clustering, and usually0.5
is sufficient.
- Specify
sovits4_for_colab.ipynb
[23/03/16] No longer need to download hubert manually
[23/04/14] Support NSF_HIFIGAN enhancer
📤 Exporting to Onnx
Use onnx_export.py
- Create a folder named
checkpoints
and open it - Create a folder in the
checkpoints
folder as your project folder, naming it after your project, for exampleaziplayer
- Rename your model as
model.pth
, the configuration file asconfig.json
, and place them in theaziplayer
folder you just created - Modify
"NyaruTaffy"
inpath = "NyaruTaffy"
in onnx_export.py to your project name,path = "aziplayer"
- Run onnx_export.py
- Wait for it to finish running. A
model.onnx
will be generated in your project folder, which is the exported model.
UI support for Onnx models
Note: For Hubert Onnx models, please use the models provided by MoeSS. Currently, they cannot be exported on their own (Hubert in fairseq has many unsupported operators and things involving constants that can cause errors or result in problems with the input/output shape and results when exported.)
CppDataProcess are some functions to preprocess data used in MoeSS
