Pretrained Models Dependency

The instructions about how to download them is displayed as follows.

Amphion Singing BigVGAN

We fine-tune the official BigVGAN pretrained model with over 120 hours singing voice data. The fine-tuned checkpoint can be downloaded here. You need to download the 400000.pt and args.json files into Amphion/pretrained/bigvgan:

Amphion
 ┣ pretrained
 ┃ ┣ bivgan
 ┃ ┃ ┣ 400000.pt
 ┃ ┃ ┣ args.json

Amphion Speech HiFi-GAN

We trained our HiFi-GAN pretrained model with 685 hours speech data. Which can be downloaded here. You need to download the whole folder of hifigan_speech into Amphion/pretrained/hifigan.

 ┃ ┣ hifigan
 ┃ ┃ ┣ hifigan_speech
 ┃ ┃ ┃ ┣ log
 ┃ ┃ ┃ ┣ result
 ┃ ┃ ┃ ┣ checkpoint
 ┃ ┃ ┃ ┣ args.json

ContentVec

You can download the pretrained ContentVec model here. Note that we use the ContentVec_legacy-500 classes checkpoint. Assume that you download the checkpoint_best_legacy_500.pt into the Amphion/pretrained/contentvec.

 ┃ ┣ contentvec
 ┃ ┃ ┣ checkpoint_best_legacy_500.pt

WeNet

You can download the pretrained WeNet model here. Take the wenetspeech pretrained checkpoint as an example, assume you download the wenetspeech_u2pp_conformer_exp.tar into the Amphion/pretrained/wenet. Unzip it and modify its configuration file as follows:

cd Amphion/pretrained/wenet

### Unzip the expt dir
tar -xvf wenetspeech_u2pp_conformer_exp.tar.gz

### Specify the updated path in train.yaml
cd 20220506_u2pp_conformer_exp
vim train.yaml
# TODO: Change the value of "cmvn_file" (Line 2) to the absolute path of the `global_cmvn` file. (Eg: [YourPath]/Amphion/pretrained/wenet/20220506_u2pp_conformer_exp/global_cmvn)

The final file struture tree is like:

Amphion
 ┣ pretrained
 ┃ ┣ wenet
 ┃ ┃ ┣ 20220506_u2pp_conformer_exp
 ┃ ┃ ┃ ┣ final.pt
 ┃ ┃ ┃ ┣ global_cmvn
 ┃ ┃ ┃ ┣ train.yaml
 ┃ ┃ ┃ ┣ units.txt

Whisper

The official pretrained whisper checkpoints can be available here. In Amphion, we use the medium whisper model by default. You can download it as follows:

cd Amphion/pretrained
mkdir whisper
cd whisper

wget https://openaipublic.azureedge.net/main/whisper/models/345ae4da62f9b3d59415adc60127b97c714f32e89e936602e85993674d08dcb1/medium.pt

The final file structure tree is like:

Amphion
 ┣ pretrained
 ┃ ┣ whisper
 ┃ ┃ ┣ medium.pt

RawNet3

The official pretrained RawNet3 checkpoints can be available here. You need to download the model.pt file and put it in the folder.

The final file structure tree is like:

Amphion
 ┣ pretrained
 ┃ ┣ rawnet3
 ┃ ┃ ┣ model.pt
