Query: Improving the Adversarial Robustness for Speaker Verification by
  Self-Supervised Learning   Previous works have shown that automatic speaker verification (ASV) is
seriously vulnerable to malicious spoofing attacks, such as replay, synthetic
speech, and recently emerged adversarial attacks. Great efforts have been
dedicated to defending ASV against replay and synthetic speech; however, only a
few approaches have been explored to deal with adversarial attacks. All the
existing approaches to tackle adversarial attacks for ASV require the knowledge
for adversarial samples generation, but it is impractical for defenders to know
the exact attack algorithms that are applied by the in-the-wild attackers. This
work is among the first to perform adversarial defense for ASV without knowing
the specific attack algorithms. Inspired by self-supervised learning models
(SSLMs) that possess the merits of alleviating the superficial noise in the
inputs and reconstructing clean samples from the interrupted ones, this work
regards adversarial perturbations as one kind of noise and conducts adversarial
defense for ASV by SSLMs. Specifically, we propose to perform adversarial
defense from two perspectives: 1) adversarial perturbation purification and 2)
adversarial perturbation detection. Experimental results show that our
detection module effectively shields the ASV by detecting adversarial samples
with an accuracy of around 80%. Moreover, since there is no common metric for
evaluating the adversarial defense performance for ASV, this work also
formalizes evaluation metrics for adversarial defense considering both
purification and detection based approaches into account. We sincerely
encourage future works to benchmark their approaches based on the proposed
evaluation framework.
