/DNS-Challenge

This repo contains the scripts, models and required files for the Interspeech 2020 Deep Noise Suppression (DNS) Challenge. We are open sourcing clean speech and noise files as well. Participants of this challenge will use the scripts from this repo to create data to train their noise suppressors. They will compare their method with our baseline noise suppressor and report the results.

Deep Noise Suppression (DNS) Challenge - Interspeech 2020

This repository contains the datasets and scripts required for the DNS challenge. For more details about the challenge, please visit https://dns-challenge.azurewebsites.net/ and refer to our paper.

Repo details:

  • The datasets directory contains the clean speech and noise clips.
  • The NSNet-baseline directory contains the inference scripts and the ONNX model for the baseline Speech Enhancer called Noise Suppression Net (NSNet)
  • noisyspeech_synthesizer_singleprocess.py - is used to synthesize noisy-clean speech pairs for training purposes.
  • noisyspeech_synthesizer.cfg - is the configuration file used to synthesize the data. Users are required to accurately specify different parameters.
  • audiolib.py - contains modules required to synthesize datasets
  • utils.py - contains some utility functions required to synthesize the data
  • unit_tests_synthesizer.py - contains the unit tests to ensure sanity of the data

Prerequisites

  • Python 3.0 and above
  • Soundfile (pip install pysoundfile), librosa

Usage:

  • Clone the repository.
  • Install Git Large File Storage for faster download of the datasets. Run git lfs install followed by git lfs track "*.wav" and git add .gitattributes
  • Edit noisyspeech_synthesizer.cfg to include the paths to clean speech and noise directories. Also, specify the paths to the destination directories and store logs.
  • Run python noisyspeech_synthesizer_singleprocess.py to synthesize the data.
