Formed in 2020, the VoicePrivacy initiative has spearheaded efforts to develop privacy-preserving solutions for speech technologies. To date, it has organized VoicePrivacy 2020, VoicePrivacy 2024, and the Attacker Challenge. VoicePrivacy 2026, the fourth edition of the challenge, starts in March 2026 and culminates in the VoicePrivacy Challenge workshop held in conjunction with the 6th Symposium on Security and Privacy in Speech Communication (SPSC), co-located with Interspeech 2026 in Sydney, Australia.
The challenge is organised with two independent tracks:
Track 1: English anonymization.
Track 2: Multilingual anonymization.
