vctk_bsrnn_small_causal

ESPnet2 ENH model

wyz/vctk_bsrnn_small_causal

This model was trained by wyz based on the universal_se_v1 recipe in espnet. More information can be found at https://github.com/Emrys365/se-scaling.

Demo: How to use in ESPnet2

Follow the ESPnet installation instructions if you haven't done that already.

To use the model in the Python interface, you could use the following code:

import soundfile as sf
from espnet2.bin.enh_inference import SeparateSpeech

# For model downloading + loading
model = SeparateSpeech.from_pretrained(
    model_tag="wyz/vctk_bsrnn_small_causal",
    normalize_output_wav=True,
    device="cuda",
)
# For loading a downloaded model
# model = SeparateSpeech(
#     train_config="exp_vctk/enh_train_enh_bsrnn_small_raw/config.yaml",
#     model_file="exp_vctk/enh_train_enh_bsrnn_small_raw/xxxx.pth",
#     normalize_output_wav=True,
#     device="cuda",
# )

audio, fs = sf.read("/path/to/noisy/utt1.flac")
enhanced = model(audio[None, :], fs=fs)[0]
