open-universe: Generative Speech Enhancement with Score-based Diffusion and Adversarial Training

This repository contains the configurations and weights for the UNIVERSE++ and UNIVERSE models implemented in open-universe.

The models were trained on the Voicebank-DEMAND dataset at 16 kHz.

The performance on the test split of Voicebank-DEMAND is given in the following table.

Usage

Start by installing open-universe. We use conda to simplify the installation.

git clone https://github.com/line/open-universe.git
cd open-universe
conda env create -f environment.yaml
conda activate open-universe
python -m pip install .

Then the models can be used as follows.

# UNIVERSE++ (default model)
python -m open_universe.bin.enhance <input/folder> <output/folder> \
  --model line-corporation/open-universe:plusplus

# UNIVERSE
python -m open_universe.bin.enhance <input/folder> <output/folder> \
  --model line-corporation/open-universe:original
