tfgridnet_urgent25

ESPnet2 ENH model

kohei0209/tfgridnet_urgent25

This model was trained by Kohei Saijo using the urgent25 recipe based on espnet.

Note that the recipe has not merged to the ESPnet main branch yet and the code is in the fork repository.

This model is provided as a pre-trained baseline model for the URGENT 2025 Challenge.

Demo: How to use in ESPnet2

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

<!-- ```bash cd espnet pip install -e . cd egs2/urgent25/enh1 ./run.sh --skip_data_prep false --skip_train true --is_tse_task true --download_model kohei0209/tfgridnet_urgent25 ``` To use the model in the Python interface, you could use the following code: > Please make sure you are using the latest ESPnet by installing from the source: > ``` > python -m pip install git+https://github.com/espnet/espnet > ``` -->

import soundfile as sf
from espnet2.bin.enh_inference import SeparateSpeech
# For model downloading + loading
model = SeparateSpeech.from_pretrained(
    model_tag="kohei0209/tfgridnet_urgent25",
    normalize_output_wav=True,
    device="cuda",
)
# For loading a downloaded model
# model = SeparateSpeech(
#     train_config="exp/xxx/config.yaml",
#     model_file="exp/xx/valid.loss.best.pth",
#     normalize_output_wav=True,
#     device="cuda",
