Website: https://aka.ms/dns-challenge Git Repo: https://github.com/microsoft/DNS-Challenge Challenge Paper:

1. Along with noise suppression, it includes de-reverberation and suppression of interfering talkers for headset and speakerphone scenarios.
2. The challenge has two tracks: (i) Headset (wired/wireless headphone, earbuds such as airpods etc.) speech enhancement; (ii) Non-headset (speakerphone, built-in mic in laptop/desktop/mobile phone/other meeting devices etc.) speech enhancement.
3. This challenge adopts the ITU-T P.835 subjective test framework to measure speech quality (SIG), background noise quality (BAK), and overall audio quality (OVRL). We modified the ITU-T P.835 to make it reliable for test clips with interfering (undesired neighboring) talkers. Along with P.835 scores, Word Accuracy (WAcc) is used to measure the performance of models.
4. Please NOTE that the intellectual property (IP) is not transferred to the challenge organizers, i.e., if code is shared/submitted, the participants remain the owners of their code (when the code is made publicly available, an appropriate license should be added).
5. There are new requirements for model related latency. Please check all requirements listed at https://www.microsoft.com/en-us/research/academic-program/deep-noise-suppression-challenge-icassp-2023/

This challenge adopted pretrained ECAPA-TDNN model available in SpeechBrain as baseline speaker embeddings models, available at https://huggingface.co/speechbrain/spkrec-ecapa-voxceleb. Participants can use any other publically available speaker embeddings model or develop their own speaker embedding extractor. Participants are encourage to explore RawNet3 models available at https://github.com/jungjee/RawNet

Previous DNS Challenge used RawNet2 speaker embeddings. So far, impact of different speaker embeddings for personalized speech enhancements is not studied in sufficient depth.

pip install speechbrain

#Compute Speaker Embeddings for your wav file with below command:

import torchaudio from speechbrain.pretrained import EncoderClassifier classifier = EncoderClassifier.from_hparams(source="speechbrain/spkrec-ecapa-voxceleb") signal, fs =torchaudio.load('tests/samples/ASR/spk1_snt1.wav') embeddings = classifier.encode_batch(signal)

This repository contains the datasets and scripts required for 5th DNS Challenge at ICASSP 2023, aka DNS Challenge 5, or simply DNS5. For more details about the challenge, please see our website and paper. For more details on the testing framework, please visit P.835.

• The datasets_fullband folder is a placeholder for the datasets. That is, our data downloader script by default will place the downloaded audio data there. After the download, it will contain clean speech, noise, and room impulse responses required for creating the training data.

• The Baseline directory contains the enhanced clips from dev testset for both tracks.

• download-dns-challenge-5-headset-training.sh - this is the script to download the data for headset (Track 1). By default, the data will be placed into the ./datasets_fullband/ folder. Please take a look at the script and uncomment the perferred download method._ Unmodified, the script performs a dry run and retrieves only the HTTP headers for each archive.

• download-dns-challenge-5-speakerphone-training.sh - this is the script to download the data for speakerphone (Track 2).

• 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 and provide the right paths to the datasets required to synthesize noisy speech.

• 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.

• requirements.txt - contains all the libraries required for synthesizing the data.

V5_dev_testset: directory containing dev testsets for both tracks. Each testclip has 10s duration and the corresponding enrollment clips with 30s duration.

BLIND testset:

https://github.com/microsoft/DNS-Challenge/tree/master/WAcc

Dev testset: available only for speakerphone track, see v5_dev_testset directory. For headset track, we are providing ASR output and list of prompts read during recording of testclips. Participants can help in correcting ASR output to generate the ground-truth transcripts. Blind testset:

The default directory structure and the sizes of the datasets of the 5th DNS Challenge are:

datasets_fullband 
+-- dev_testset 
+-- impulse_responses 5.9G
+-- noise_fullband 58G
\-- clean_fullband 827G
    +-- emotional_speech 2.4G
    +-- french_speech 62G
    +-- german_speech 319G
    +-- italian_speech 42G
    +-- read_speech 299G
    +-- russian_speech 12G
    +-- spanish_speech 65G
    +-- vctk_wav48_silence_trimmed 27G
    \-- VocalSet_48kHz_mono 974M

In all, you will need about 1TB to store the unpacked data. Archived, the same data takes about 550GB total.

A CSV file containing file sizes and SHA1 checksums for audio clips in both Real-time and Personalized DNS datasets is available at: dns5-datasets-files-sha1.csv.bz2. The archive is 41.3MB in size and can be read in Python like this:

import pandas as pd

sha1sums = pd.read_csv("dns5-datasets-files-sha1.csv.bz2", names=["size", "sha1", "path"])

• Python 3.6 and above
• Python libraries: soundfile, librosa

NOTE: git LFS is no longer required for DNS Challenge. Please use the download-dns-challenge-5*.sh scripts in this repo to download the data.

1. Install Python libraries

pip3 install soundfile librosa

2. Clone the repository.

git clone https://github.com/microsoft/DNS-Challenge

3. Edit noisyspeech_synthesizer.cfg to specify the required parameters described in the file and include the paths to clean speech, noise and impulse response related csv files. Also, specify the paths to the destination directories and store the logs.

4. Create dataset

python3 noisyspeech_synthesizer_singleprocess.py
