Samples | Paper | Pretrained Models

0. Setup Conda Environment

conda env create -f environment.yaml
conda activate betavae-vc-env

1. Data preprocessing

• Download corpus

1. English: VCTK
2. Mandarin: AISHELL3

• Modify the paths specified in configs/haparams.py: corpus_dir for both VCTK and AiShell3, dataset_dir for extracted features and TFRecord files.
• Prepare the dataset for training:

python preprocess.py

2. Training

CUDA_VISIBLE_DEVICES=0 TF_FORCE_GPU_ALLOW_GROWTH=true python train.py --out_dir ./outputs --data_dir /path/to/save/features/tfrecords

3. Inference

# inference from mels
# test-mels.txt contains list of paths for mel-spectrograms with *.npy format, one path per line
CUDA_VISIBLE_DEVICES=0 TF_FORCE_GPU_ALLOW_GROWTH=true python inference-from-mel.py --ckpt_path ./outputs/models/ckpt-500 --test_dir outputs/tests --src_mels test-mels.txt --ref_mels test-mels.txt

# inference from wavs
# test-wavs.txt contains list of paths for speech with *.wav format, one path per line
CUDA_VISIBLE_DEVICES=0 TF_FORCE_GPU_ALLOW_GROWTH=true python inference-from-wav.py --ckpt_path ./outputs/models/ckpt-500 --test_dir outputs/tests --src_wavs test-wavs.txt --ref_wavs test-wavs.txt

4. Latent extraction

CUDA_VISIBLE_DEVICES=0 TF_FORCE_GPU_ALLOW_GROWTH=true python feature_extraction.py --data_dir /path/to/save/features/tfrecords --save_dir ./outputs/features --ckpt_path ./outputs/models/ckpt-300

5. EER computation based on the extracted latents

# compute EER using content embeddings
python tests/compute_eer.py --data_dir ./outputs/features/EN --mode content
# compute EER using speaker embeddings
python tests/compute_eer.py --data_dir ./outputs/features/EN --mode spk
