SASV Challenge 2022: A Spoofing Aware Speaker Verification Challenge Evaluation Plan
This addresses the need for robust speaker verification systems in security applications, but it is incremental as it builds on existing ASV and CM methods through a challenge framework.
The paper tackles the problem of integrating automatic speaker verification with spoofing countermeasures by introducing the first SASV challenge, which aims to develop systems that can simultaneously verify speakers and detect spoofing attacks.
ASV (automatic speaker verification) systems are intrinsically required to reject both non-target (e.g., voice uttered by different speaker) and spoofed (e.g., synthesised or converted) inputs. However, there is little consideration for how ASV systems themselves should be adapted when they are expected to encounter spoofing attacks, nor when they operate in tandem with CMs (spoofing countermeasures), much less how both systems should be jointly optimised. The goal of the first SASV (spoofing-aware speaker verification) challenge, a special sesscion in ISCA INTERSPEECH 2022, is to promote development of integrated systems that can perform ASV and CM simultaneously.
