This project differs fundamentally from VITS, as it focuses on Singing Voice Conversion (SVC) rather than Text-to-Speech (TTS). In this project, TTS functionality is not supported, and VITS is incapable of performing SVC tasks. It's important to note that the models used in these two projects are not interchangeable or universally applicable.
The purpose of this project was to enable developers to have their beloved anime characters perform singing tasks. The developers' intention was to focus solely on fictional characters and avoid any involvement of real individuals, anything related to real individuals deviates from the developer's original intention.
This project is an open-source, offline endeavor, and all members of SvcDevelopTeam, as well as other developers and maintainers involved (hereinafter referred to as contributors), have no control over the project. The contributors have never provided any form of assistance to any organization or individual, including but not limited to dataset extraction, dataset processing, computing support, training support, inference, and so on. The contributors do not and cannot be aware of the purposes for which users utilize the project. Therefore, any AI models and synthesized audio produced through the training of this project are unrelated to the contributors. Any issues or consequences arising from their use are the sole responsibility of the user.
This project is run completely offline and does not collect any user information or gather 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 serves as a framework only and does not possess speech synthesis functionality by itself. All functionalities require users to train the models independently. Furthermore, this project does not come bundled with any models, and any secondary distributed projects are independent of the contributors of this project.
Warning: Please ensure that you address any authorization issues related to the dataset on your own. You bear full responsibility for any problems arising from the usage of non-authorized datasets for training, as well as any resulting consequences. The repository and its maintainer, svc develop team, disclaim any association with or liability for the consequences.
- This project is exclusively established for academic purposes, aiming to facilitate communication and learning. It is not intended for deployment in production environments.
- Any sovits-based video posted to a video platform must clearly specify in the introduction the input source vocals and audio used for the voice changer conversion, e.g., if you use someone else's video/audio and convert it by separating the vocals as the input source, you must give a clear link to the original video or music; if you use your own vocals or a voice synthesized by another voice synthesis engine as the input source, you must also state this in your introduction.
- You are solely responsible for any infringement issues caused by the input source and all consequences. When using other commercial vocal synthesis software as an input source, please ensure that you comply with the regulations of that software, noting that the regulations of many vocal synthesis engines explicitly state that they cannot be used to convert input sources!
- Engaging in illegal activities, as well as religious and political activities, is strictly prohibited when using this project. The project developers vehemently oppose the aforementioned activities. If you disagree with this provision, the usage of the project is prohibited.
- If you continue to use the program, you will be deemed to have agreed to the terms and conditions set forth in README and README has discouraged you and is not responsible for any subsequent problems.
- If you intend to employ this project for any other purposes, kindly contact and inform the maintainers of this repository in advance.
The singing voice conversion model uses SoftVC content encoder to extract speech features from the source audio. These feature vectors are directly fed into VITS without the need for conversion to a text-based intermediate representation. As a result, the pitch and intonations of the original audio are preserved. Meanwhile, the vocoder was replaced with NSF HiFiGAN to solve the problem of sound interruption.
- Feature input is changed to the 12th Layer of Content Vec Transformer output, And compatible with 4.0 branches.
- Update the shallow diffusion, you can use the shallow diffusion model to improve the sound quality.
- Added Whisper-PPG encoder support
- Added static/dynamic sound fusion
- Added loudness embedding
- Added Functionality of feature retrieval from RVC
- To support the 4.0 model and incorporate the speech encoder, you can make modifications to the
config.jsonfile. Add thespeech_encoderfield to the "model" section as shown below:
"model": {
.........
"ssl_dim": 256,
"n_speakers": 200,
"speech_encoder":"vec256l9"
}
Based on our testing, we have determined that the project runs stable on Python 3.8.9.

Simply place the dataset in the dataset_raw directory with the following file structure:
dataset_raw
├───speaker0
│ ├───xxx1-xxx1.wav
│ ├───...
│ └───Lxx-0xx8.wav
└───speaker1
├───xx2-0xxx2.wav
├───...
└───xxx7-xxx007.wav
There are no specific restrictions on the format of the name for each audio file (naming conventions such as 000001.wav to 999999.wav are also valid), but the file type must be `WAV``.
You can customize the speaker's name as showed below:

└───25788785-20221210-200143-856_01_(Vocals)_0_0.wav
To avoid video memory overflow during training or pre-processing, it is recommended to limit the length of audio clips. Cutting the audio to a length of "5s - 15s" is more recommended. Slightly longer times are acceptable, however, excessively long clips may cause problems such as torch.cuda.OutOfMemoryError.
To facilitate the slicing process, you can use audio-slicer-GUI or audio-slicer-CLI
In general, only the Minimum Interval needs to be adjusted. For spoken audio, the default value usually suffices, while for singing audio, it can be adjusted to around 100 or even 50, depending on the specific requirements.
After slicing, it is recommended to remove any audio clips that are excessively long or too short.
If you are using whisper-ppg encoder for training, the audio clips must shorter than 30s.
python resample.pyAlthough this project has resample.py scripts for resampling, mono and loudness matching, the default loudness matching is to match to 0db. This can cause damage to the sound quality. While python's loudness matching package pyloudnorm does not limit the level, this can lead to sonic boom. Therefore, it is recommended to consider using professional sound processing software, such as adobe audition for loudness matching. If you are already using other software for loudness matching, add the parameter -skip_loudnorm to the run command:
python resample.py --skip_loudnorm2. Automatically split the dataset into training and validation sets, and generate configuration files.
python preprocess_flist_config.py --speech_encoder vec768l12speech_encoder has the following options
vec768l12
vec256l9
hubertsoft
whisper-ppg
cnhubertlarge
dphubert
whisper-ppg-large
wavlmbase+
If the speech_encoder argument is omitted, the default value is vec768l12
Use loudness embedding
Add --vol_aug if you want to enable loudness embedding:
python preprocess_flist_config.py --speech_encoder vec768l12 --vol_augAfter enabling loudness embedding, the trained model will match the loudness of the input source; otherwise, it will match the loudness of the training set.
-
keep_ckpts: Keep the the the number of previous models during training. Set to0to keep them all. Default is3. -

python preprocess_hubert_f0.py --f0_predictor diof0_predictor has the following options
crepe
dio
pm
harvest
rmvpe
fcpe
If the training set is too noisy,it is recommended to use crepe to handle f0
If the f0_predictor parameter is omitted, the default value is rmvpe
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_diffSpeed Up preprocess
If your dataset is pretty large,you can increase the param --num_processes like that:
python preprocess_hubert_f0.py --f0_predictor dio --num_processes 8All the worker will be assigned to different GPU if you have more than one GPUs.
After completing the above steps, the dataset directory will contain the preprocessed data, and the dataset_raw folder can be deleted.
python train.py -c configs/config.json -m 44kHere is a method that allows you to pause training and save the model at any time. Simply create a stop.txt file in the running directory, and the training will stop and save the model after the next step.
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.yamlDuring training, the model files will be saved to logs/44k, and the diffusion model will be saved to 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 therawfolder.-t|--trans: pitch shift, supports positive and negative (semitone) values.-s|--spk_list: Select the speaker ID to use for conversion.-cl|--clip: Forced audio clipping, set to 0 to disable(default), setting it to a non-zero value (duration in seconds) to enable.
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 a F0 predictor, options arecrepe,pm,dio,harvest,rmvpe,fcpe, default value ispm(note: f0 mean pooling will be enable when usingcrepe)-a|--auto_predict_f0: automatic pitch prediction, do not enable this when converting singing voices as it can cause serious pitch issues.-cm|--cluster_model_path: Cluster model or feature retrieval index path, if left blank, it will be automatically set as the default path of these models. If there is no training cluster or feature retrieval, fill in at will.-cr|--cluster_infer_ratio: The proportion of clustering scheme or feature retrieval ranges from 0 to 1. If there is no training clustering model or feature retrieval, the default is 0.-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 disabled by default.-shd|--shallow_diffusion: Whether to use shallow diffusion, which can solve some electrical sound problems after use. This option is disabled by default. When this option is enabled, NSF_HIFIGAN enhancer will be disabled-usm|--use_spk_mix: whether to use dynamic voice fusion-lea|--loudness_envelope_adjustment：The adjustment of the input source's loudness envelope in relation to the fusion ratio of the output loudness envelope. The closer to 1, the more the output loudness envelope is used-fr|--feature_retrieval：Whether to use feature retrieval If clustering model is used, it will be disabled, andcmandcrparameters will become the index path and mixing ratio of feature retrieval
Shallow diffusion settings:
-dm|--diffusion_model_path: Diffusion model path-dc|--diffusion_config_path: Diffusion config file path-ks|--k_step: The larger the number of k_steps, the closer it is to the result of the diffusion model. The default is 100-od|--only_diffusion: Whether to use Only diffusion mode, which does not load the sovits model to only use diffusion model inference-se|--second_encoding：which involves applying an additional encoding to the original audio before shallow diffusion. This option can yield varying results - sometimes positive and sometimes negative.
If inferencing using whisper-ppg speech encoder, you need to set --clip to 25 and -lg to 1. Otherwise it will fail to infer properly.
If you are satisfied with the previous results, or if you do not feel you understand what follows, you can skip it and it will have no effect on the use of the model. The impact of these optional settings mentioned is relatively small, and while they may have some impact on specific datasets, in most cases the difference may not be significant.
During the training of the 4.0 model, an f0 predictor is also trained, which enables automatic pitch prediction during voice conversion. However, if the results are not satisfactory, manual pitch prediction can be used instead. Please note that when converting singing voices, it is advised not to enable this feature as it may cause significant pitch shifting.

Introduction: The clustering scheme implemented in this model aims to reduce timbre leakage and enhance the similarity of the trained model to the target's timbre, although the effect may not be very pronounced. However, relying solely on clustering can reduce the model's clarity and make it sound less distinct. Therefore, a fusion method is adopted in this model to control the balance between the clustering and non-clustering approaches. This allows manual adjustment of the trade-off between "sounding like the target's timbre" and "have clear enunciation" to find an optimal balance.
No changes are required in the existing steps. Simply train an additional clustering model, which incurs relatively low training costs.
- Training process:
- Train on a machine with good CPU performance. According to extant 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. If not specified, the default islogs/44k/kmeans_10000.pt. - Specify
cluster_infer_ratioininference_main.py, where0means not using clustering at all,1means only using clustering, and usually0.5is sufficient.
- Specify
Introduction: As with the clustering scheme, the timbre leakage can be reduced, the enunciation is slightly better than clustering, but it will reduce the inference speed. By employing the fusion method, it becomes possible to linearly control the balance between feature retrieval and non-feature retrieval, allowing for fine-tuning of the desired proportion.
- Training process: First, it needs to be executed after generating hubert and f0:
python train_index.py -c configs/config.jsonThe output of the model will be in logs/44k/feature_and_index.pkl
- Inference process:
- The
--feature_retrievalneeds to be formulated first, and the clustering mode automatically switches to the feature retrieval mode. - Specify
cluster_model_pathininference_main.py. If not specified, the default islogs/44k/feature_and_index.pkl. - Specify
cluster_infer_ratioininference_main.py, where0means not using feature retrieval at all,1means only using feature retrieval, and usually0.5is sufficient.
- The
The generated model contains data that is needed for further training. If you confirm that the model is final and not be used in further training, it is safe to remove these data to get smaller file size (about 1/3).
# Example
python compress_model.py -c="configs/config.json" -i="logs/44k/G_30400.pth" -o="logs/44k/release.pth"Refer to webUI.py file for stable Timbre mixing of the gadget/lab feature.
Introduction: This function can combine multiple models into one model (convex combination or linear combination of multiple model parameters) to create mixed voice that do not exist in reality
Note:
- This feature is only supported for single-speaker models
- If you force a multi-speaker model, it is critical to make sure there are the same number of speakers in each model. This will ensure that sounds with the same SpeakerID can be mixed correctly.
- Ensure that the
modelfields in config.json of all models to be mixed are the same - The mixed model can use any config.json file from the models being synthesized. However, the clustering model will not be functional after mixed.
- When batch uploading models, it is best to put the models into a folder and upload them together after selecting them
- It is suggested to adjust the mixing ratio between 0 and 100, or to other numbers, but unknown effects will occur in the linear combination mode
- After mixing, the file named output.pth will be saved in the root directory of the project
- Convex combination mode will perform Softmax to add the mix ratio to 1, while linear combination mode will not
Refer to the spkmix.py file for an introduction to dynamic timbre mixing
Character mix track writing rules:
Role ID: [[Start time 1, end time 1, start value 1, start value 1], [Start time 2, end time 2, start value 2]]
The start time must be the same as the end time of the previous one. The first start time must be 0, and the last end time must be 1 (time ranges from 0 to 1).
All roles must be filled in. For unused roles, fill [[0., 1., 0., 0.]]
The fusion value can be filled in arbitrarily, and the linear change from the start value to the end value within the specified period of time. The
internal linear combination will be automatically guaranteed to be 1 (convex combination condition), so it can be used safely
Use the --use_spk_mix parameter when reasoning to enable dynamic timbre mixing
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.)
