We are delighted to announce the 4th edition of the Automatic Speaker Verification Spoofing and Countermeasures. ASVspoof 2021 will be organised as a satellite event in conjunction with Interspeech 2021

ASVspoof 2021 will comprise three separate sub-challenges:

• a logical access sub-challenge extending the 2019 challenge with a focus on robustness to channel variation;

• a physical access sub-challenge similar to the 2019 setup, but with recordings made in real physical environments;

• speech deepfake detection sub-challenge (no ASV).

While no new training and no new development data will be released, new evaluation data will be released for each of the three conditions.

Participants will be encouraged to prepare their own training and development data by using ASVspoof 2019 training and development subsets and data augmentation techniques, e.g. to simulate channel variability. The challenge evaluation plan will be released in the first quarter of 2021, with a submission deadline in the second quarter.
