Transformer for Singing Voice Conversion
This is an implementation of vanilla transformer encoder/conformer as acoustic model for singing voice conversion.
There are four stages in total:
- Data preparation
- Features extraction
- Training
- Inference/conversion
NOTE: You need to run every command of this recipe in the
Amphion
root path:
cd Amphion
1. Data Preparation
Dataset Download
By default, we utilize the five datasets for training: M4Singer, Opencpop, OpenSinger, SVCC, and VCTK. How to download them is detailed here.
Configuration
Specify the dataset paths in exp_config.json
. Note that you can change the dataset
list to use your preferred datasets.
"dataset": [
"m4singer",
"opencpop",
"opensinger",
"svcc",
"vctk"
],
"dataset_path": {
// TODO: Fill in your dataset path
"m4singer": "[M4Singer dataset path]",
"opencpop": "[Opencpop dataset path]",
"opensinger": "[OpenSinger dataset path]",
"svcc": "[SVCC dataset path]",
"vctk": "[VCTK dataset path]"
},
2. Features Extraction
Content-based Pretrained Models Download
By default, we utilize the Whisper and ContentVec to extract content features. How to download them is detailed here.
Configuration
Specify the dataset path and the output path for saving the processed data and the training model in exp_config.json
:
// TODO: Fill in the output log path. The default value is "Amphion/ckpts/svc"
"log_dir": "ckpts/svc",
"preprocess": {
// TODO: Fill in the output data path. The default value is "Amphion/data"
"processed_dir": "data",
...
},
Run
Run the run.sh
as the preproces stage (set --stage 1
).
sh egs/svc/TransformerSVC/run.sh --stage 1
NOTE: The
CUDA_VISIBLE_DEVICES
is set as"0"
in default. You can change it when runningrun.sh
by specifying such as--gpu "1"
.
3. Training
Configuration
Specify the detailed configuration for transformer block in exp_config.json
. For key type
, conformer
and transformer
are supported:
"model": {
...
"transformer":{
// 'conformer' or 'transformer'
"type": "conformer",
"input_dim": 384,
"output_dim": 100,
"n_heads": 2,
"n_layers": 6,
"filter_channels":512,
"dropout":0.1,
}
}
We provide the default hyparameters in the exp_config.json
. They can work on single NVIDIA-24g GPU. You can adjust them based on you GPU machines.
"train": {
"batch_size": 32,
...
"adamw": {
"lr": 2.0e-4
},
...
}
Run
Run the run.sh
as the training stage (set --stage 2
). Specify a experimental name to run the following command. The tensorboard logs and checkpoints will be saved in Amphion/ckpts/svc/[YourExptName]
.
sh egs/svc/TransformerSVC/run.sh --stage 2 --name [YourExptName]
NOTE: The
CUDA_VISIBLE_DEVICES
is set as"0"
in default. You can change it when runningrun.sh
by specifying such as--gpu "0,1,2,3"
.
4. Inference/Conversion
Pretrained Vocoder Download
We fine-tune the official BigVGAN pretrained model with over 120 hours singing voice data. The benifits of fine-tuning has been investigated in our paper (see this demo page). The final pretrained singing voice vocoder is released here (called Amphion Singing BigVGAN
).
Run
For inference/conversion, you need to specify the following configurations when running run.sh
:
Parameters | Description | Example |
---|---|---|
--infer_expt_dir |
The experimental directory which contains checkpoint |
Amphion/ckpts/svc/[YourExptName] |
--infer_output_dir |
The output directory to save inferred audios. | Amphion/ckpts/svc/[YourExptName]/result |
--infer_source_file or --infer_source_audio_dir |
The inference source (can be a json file or a dir). | The infer_source_file could be Amphion/data/[YourDataset]/test.json , and the infer_source_audio_dir is a folder which includes several audio files (*.wav, *.mp3 or *.flac). |
--infer_target_speaker |
The target speaker you want to convert into. You can refer to Amphion/ckpts/svc/[YourExptName]/singers.json to choose a trained speaker. |
For opencpop dataset, the speaker name would be opencpop_female1 . |
--infer_key_shift |
How many semitones you want to transpose. | "autoshfit" (by default), 3 , -3 , etc. |
For example, if you want to make opencpop_female1
sing the songs in the [Your Audios Folder]
, just run:
cd Amphion
sh egs/svc/TransformerSVC/run.sh --stage 3 --gpu "0" \
--infer_expt_dir Amphion/ckpts/svc/[YourExptName] \
--infer_output_dir Amphion/ckpts/svc/[YourExptName]/result \
--infer_source_audio_dir [Your Audios Folder] \
--infer_target_speaker "opencpop_female1" \
--infer_key_shift "autoshift"
