Can spoofing countermeasure and speaker verification systems be jointly optimised?

1 code implementation13 Mar 2023 Wanying Ge, Hemlata Tak, Massimiliano Todisco, Nicholas Evans

Spoofing countermeasure (CM) and automatic speaker verification (ASV) sub-systems can be used in tandem with a backend classifier as a solution to the spoofing aware speaker verification (SASV) task.

On the potential of jointly-optimised solutions to spoofing attack detection and automatic speaker verification

1 code implementation1 Sep 2022 Wanying Ge, Hemlata Tak, Massimiliano Todisco, Nicholas Evans

The spoofing-aware speaker verification (SASV) challenge was designed to promote the study of jointly-optimised solutions to accomplish the traditionally separately-optimised tasks of spoofing detection and speaker verification.

Explainable deepfake and spoofing detection: an attack analysis using SHapley Additive exPlanations

1 code implementation28 Feb 2022 Wanying Ge, Massimiliano Todisco, Nicholas Evans

Despite several years of research in deepfake and spoofing detection for automatic speaker verification, little is known about the artefacts that classifiers use to distinguish between bona fide and spoofed utterances.

Raw Differentiable Architecture Search for Speech Deepfake and Spoofing Detection

1 code implementation26 Jul 2021 Wanying Ge, Jose Patino, Massimiliano Todisco, Nicholas Evans

End-to-end approaches to anti-spoofing, especially those which operate directly upon the raw signal, are starting to be competitive with their more traditional counterparts.
