Vocoder drift compensation by x-vector alignment in speaker anonymisation

2023 · arXiv (Cornell University)

For the most popular x-vector-based approaches to speaker anonymisation, the bulk of the anonymisation can stem from vocoding rather than from the core anonymisation function which is used to substitute an original speaker x-vector with …

MDD: A Mask Diffusion Detector to Protect Speaker Verification Systems from Adversarial Perturbations

2025

Speaker verification systems are increasingly deployed in security-sensitive applications but remain highly vulnerable to adversarial perturbations. In this work, we propose the Mask Diffusion Detector (MDD), a novel adversarial detection and purification framework based on …
