Recipe for VoicePrivacy Challenge 2020

Please visit the challenge website for more information about the Challenge.

Install

1. git clone --recurse-submodules https://github.com/Voice-Privacy-Challenge/Voice-Privacy-Challenge-2020.git
2. ./install.sh

Running the recipe

The recipe uses the pre-trained models of anonymization. To run the baseline system with evaluation:

1. cd baseline
2. run ./run.sh. In run.sh, to download models and data the user will be requested the password which is provided during the Challenge registration.

General information

For more details about the baseline and data, please see The VoicePrivacy 2020 Challenge Evaluation Plan

For the latest updates in the baseline and evaluation scripts, please visit News and updates page

The deadline to submit results has passed. To access the baseline models and development/evaluation data, please send an email to organisers@lists.voiceprivacychallenge.org with “VoicePrivacy-2020" as the subject line. The mail body should include: (i) the name of the contact person; (ii) country; (iii) status (academic/nonacademic).

Data

Training data

The dataset for anonymization system traing consists of subsets from the following corpora*:

• LibriSpeech - train-clean-100, train-other-500
• LibriTTS - train-clean-100, train-other-500
• VoxCeleb 1 & 2 - all

*only specified subsets of these corpora can be used for training.

Development and evaluation data

• VCTK - subsets vctk_dev and vctk_test are download from server in run.sh
• LibriSpeech - subsets libri_dev and libri_test are download from server in run.sh

Baseline-1: Anonymization using x-vectors and neural waveform models

This is the primary (default) baseline.

Models

The baseline system uses several independent models:

1. ASR acoustic model to extract BN features (1_asr_am) - trained on LibriSpeech-train-clean-100 and LibriSpeech-train-other-500
2. X-vector extractor (2_xvect_extr) - trained on VoxCeleb 1 & 2.
3. Speech synthesis (SS) acoustic model (3_ss_am) - trained on LibriTTS-train-clean-100.
4. Neural source filter (NSF) model (4_nsf) - trained on LibriTTS-train-clean-100.

All the pretrained models are provided as part of this baseline (downloaded by ./baseline/local/download_models.sh)

Baseline-2: Anonymization using McAdams coefficient

This is an additional baseline.

To run: ./run.sh --mcadams true

It does not require any training data and is based upon simple signal processing techniques using the McAdams coefficient.

Results

The result file with all the metrics and all datasets for submission will be generated in: ./baseline/exp/results-date-time/results.txt

Please see

New anonymization metrics and post-evaluation

For the post-evaluation analysis novel anonymization metrics have been integrated to the baseline evaluation:

• The Privacy ZEBRA: Zero Evidence Biometric Recognition Assessment: https://arxiv.org/pdf/2005.09413.pdf
• Speech Pseudonymisation Assessment Using Voice Similarity Matrices: https://arxiv.org/pdf/2008.13144.pdf
