SI-SNR Estimator introduced for the REAL-M dataset

This repository provides the Separator models to be able to train a blind SI-SNR estimator with the recipe provided in the SpeechBrain repository to complement the REAL-M real-life speech separation dataset.

The SI-SNR estimator is trained with a recordings from the WHAMR! and LibriMix datasets. We used a mixture of 9 separators to create the training data on the fly.

This model is released together with the REAL-M dataset for source separation on in-the-wild speech mixtures.

The REAL-M dataset can downloaded from this link. The paper for the REAL-M dataset can be found on this arxiv link.

Install SpeechBrain

First of all, currently you need to install SpeechBrain:

pip install speechbrain

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.


The model was trained with SpeechBrain (fc2eabb7).

To train it from scratch follows these steps:

  1. Clone SpeechBrain:

git clone https://github.com/speechbrain/speechbrain/
  1. Install it:

cd speechbrain

pip install -r requirements.txt

pip install -e .
  1. Run Training:

cd recipes/REAL-M/sisnr-estimation

python train.py hparams/pool_sisnrestimator.yaml --data_folder /yourLibri2Mixpath --base_folder_dm /yourLibriSpeechpath --rir_path /yourpathforwhamrRIRs --dynamic_mixing True --use_whamr_train True --whamr_data_folder /yourpath/whamr --base_folder_dm_whamr /yourpath/wsj0-processed/si_tr_s

You can find our training results (models, logs, etc) here.


The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
