Watch What You Pretrain For: Targeted, Transferable Adversarial Examples on Self-Supervised Speech Recognition models. (arXiv:2209.13523v2 [cs.LG] UPDATED)

A targeted adversarial attack produces audio samples that can force an
Automatic Speech Recognition (ASR) system to output attacker-chosen text. To
exploit ASR models in real-world, black-box settings, an adversary can leverage
the transferability property, i.e. that an adversarial sample produced for a
proxy ASR can also fool a different remote ASR. However recent work has shown
that transferability against large ASR models is very difficult. In this work,
we show that modern ASR architectures, specifically ones based on
Self-Supervised …
