论文摘要
本文提出了一种对自动语音识别系统的黑盒对抗攻击方法。一些研究试图攻击神经网络以进行语音识别。但是,这些方法并未考虑产生的对抗性示例的鲁棒性,以防止定时滞后。本文提出的方法采用了进化多目标优化(EMO),该优化允许在黑盒方案下生成健壮的对抗示例。实验结果表明,该提出的方法成功地生成了无调整的对抗性示例,这些示例足以与正时滞后相对于时间延迟,因此攻击者无需将其与目标语音进行播放的时间。
This paper proposes a black-box adversarial attack method to automatic speech recognition systems. Some studies have attempted to attack neural networks for speech recognition; however, these methods did not consider the robustness of generated adversarial examples against timing lag with a target speech. The proposed method in this paper adopts Evolutionary Multi-objective Optimization (EMO)that allows it generating robust adversarial examples under black-box scenario. Experimental results showed that the proposed method successfully generated adjust-free adversarial examples, which are sufficiently robust against timing lag so that an attacker does not need to take the timing of playing it against the target speech.
