GhostPrefix 攻击在无需同步的情况下操纵 ASR 系统

研究人员开发了 GhostPrefix,这是一种无需与目标音频同步即可操纵自动语音识别 (ASR) 系统的新颖方法。该技术通过在任何实时语音前添加一个简短、可重用的音频片段,从而实现对 ASR 输出的实时控制。GhostPrefix 利用令牌级和表示级目标,在各种语音环境中保持稳定的对抗效果,并可用于语义引导、转录劫持或转录降级。该攻击在数字和实际(over-the-air)环境中均显示出高成功率,影响了语音助手和 AI 笔记工具等下游应用。 AI

影响 这项研究揭示了 ASR 系统的一个新漏洞,可能影响语音控制的 AI 应用的安全性与可靠性。

    GhostPrefix: Synchronization-Free Universal Prefix Attacks for ASR Manipulation

    arXiv:2610.42026v1 Announce Type: new Abstract: We present GhostPrefix, the first synchronization-free universal adversarial prefix attack against automatic speech recognition (ASR) systems. Unlike prior audio attacks, which are typically crafted per utterance, require synchroniz…
