✨ A studio that contains f0 curve editor, speaker mix timeline editor and other features (The purpose of the Onnx model) : MoeVoiceStudio(Comming soon)
✨ 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
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.
This project is an open source, offline project, and all members of SvcDevelopTeam and all developers and maintainers of this project (hereinafter referred to as contributors) have no control over this project. The contributor of this project has never provided any organization or individual with any form of assistance, including but not limited to data set extraction, data set processing, computing support, training support, infering, etc. Contributors to the project do not and cannot know what users are using the project for. Therefore, all AI models and synthesized audio based on the training of this project have nothing to do with the contributors of this project. All problems arising therefrom shall be borne by the user.
This project is run completely offline and cannot collect any user information or obtain user input data. Therefore, contributors to this project are not aware of all user input and models and therefore are not responsible for any user input.
This project is only a framework project, which does not have the function of speech synthesis itself, and all the functions require the user to train the model themselves. Meanwhile, there is no model attached to this project, and any secondary distributed project has nothing to do with the contributors of this project
Warning: Please solve the authorization problem of the dataset on your own. You shall be solely responsible for any problems caused by the use of non-authorized datasets for training and all consequences thereof.The repository and its maintainer, svc develop team, have nothing to do with the consequences!
- This project is established for academic exchange purposes only and is intended for communication and learning purposes. It is not intended for production environments.
- Any videos based on sovits that are published on video platforms must clearly indicate in the description that they are used for voice changing and specify the input source of the voice or audio, for example, using videos or audios published by others and separating the vocals as input source for conversion, which must provide clear original video or music links. If your own voice or other synthesized voices from other commercial vocal synthesis software are used as the input source for conversion, you must also explain it in the description.
- You shall be solely responsible for any infringement problems caused by the input source. When using other commercial vocal synthesis software as input source, please ensure that you comply with the terms of use of the software. Note that many vocal synthesis engines clearly state in their terms of use that they cannot be used for input source conversion.

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.
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.
- Feature input is changed to Content Vec Transformer output of 12 layer, the branch is not compatible with 4.0 model
- Update the shallow diffusion, you can use the shallow diffusion model to improve the sound quality
- You can support the 4.0 model by modifying the config.json of the 4.0 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"
}
After conducting tests, we believe that the project runs stably on Python 3.8.9.

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.
python resample.py2. Automatically split the dataset into training and validation sets, and generate configuration files.
python preprocess_flist_config.py --speech_encoder vec768l12speech_encoder has three choices
vec768l12
vec256l9
hubertsoft
If the speech_encoder argument is omitted, the default value is vec768l12
python preprocess_hubert_f0.py --f0_predictor diof0_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
If you want shallow diffusion (optional), you need to add the --use_diff parameter, for example
python preprocess_hubert_f0.py --f0_predictor dio --use_diffAfter completing the above steps, the dataset directory will contain the preprocessed data, and the dataset_raw folder can be deleted.
-
keep_ckpts: Keep the lastkeep_ckptsmodels during training. Set to0will 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.
If the shallow diffusion function is needed, the diffusion model needs to be trained. The diffusion model training method is as follows:
python train_diff.py -c configs/diffusion.yamlpython train.py -c configs/config.json -m 44kAfter the model training, the model file is saved in the directory logs/44k, and the diffusion model is stored under logs/44k/diffusion
# 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.-shd|--shallow_diffusion：Whether to use shallow diffusion, which can solve some electrical sound problems after use. This option is turned off by default. When this option is enabled, NSF_HIFIGAN intensifier will be disabled
Shallow diffusion setting
-dm|--diffusion_model_path：Diffusion model path-dc|--diffusion_config_path：Diffusion model profile path-ks|--k_step：The larger the number of diffusion steps, the closer it is to the result of the diffusion model. The default is 100-od|---only_diffusion：Only diffusion mode, which does not load the sovits model to the diffusion model inference
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.)
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_f0to true in inference_main.
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. - The clustering model can currently be trained using the gpu by executing
python cluster/train_cluster.py --gpu
- Inference process:
- Specify
cluster_model_pathininference_main.py. - Specify
cluster_infer_ratioininference_main.py, where0means not using clustering at all,1means only using clustering, and usually0.5is sufficient.
- Specify
[23/03/16] No longer need to download hubert manually
[23/04/14] Support NSF_HIFIGAN enhancer
Use onnx_export.py
- Create a folder named
checkpointsand open it - Create a folder in the
checkpointsfolder 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 theaziplayerfolder you just created - Modify
"NyaruTaffy"inpath = "NyaruTaffy"in onnx_export.py to your project name,path = "aziplayer"（onnx_export_speaker_mix makes you can mix speaker's voice） - Run onnx_export.py
- Wait for it to finish running. A
model.onnxwill be generated in your project folder, which is the exported model.
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.)
For some reason the author deleted the original repository. Because of the negligence of the organization members, the contributor list was cleared because all files were directly reuploaded to this repository at the beginning of the reconstruction of this repository. Now add a previous contributor list to README.md.
Some members have not listed according to their personal wishes.
