摘要:

自动语音识别(ASR)系统普遍存在于我们的日常设备中。它们容易受到对抗攻击的攻击,其中操纵的输入样本欺骗了ASR系统的识别。虽然已经分析了各种英语ASR系统的对抗性示例,但还没有跨语言比较脆弱性分析。我们以Deepspeech为例,比较了德语和英语ASR系统的可攻击性。我们调查,如果一个语言模型是更容易受到操纵比其他。我们的实验结果表明,在成功生成对抗性示例所需的计算工作量方面,英语和德语之间存在统计上的显著差异。这一结果鼓励进一步研究的语言依赖特性的鲁棒性分析的ASR。

英文摘要:

Automatic speech recognition (ASR) systems are ubiquitously present in our daily devices. They are vulnerable to adversarial attacks, where manipulated input samples fool the ASR system's recognition. While adversarial examples for various English ASR systems have already been analyzed, there exists no inter-language comparative vulnerability analysis. We compare the attackability of a German and an English ASR system, taking Deepspeech as an example. We investigate if one of the language models is more susceptible to manipulations than the other. The results of our experiments suggest statistically significant differences between English and German in terms of computational effort necessary for the successful generation of adversarial examples. This result encourages further research in language-dependent characteristics in the robustness analysis of ASR.
