摘要:

虚假音频检测是一个新兴的热门课题。越来越多的文献致力于检测虚假语音,这些语音大多由文本转语音(TTS)或语音转换(VC)生成。然而,针对冒充(impersonation)的对抗措施仍是一个探索不足的领域。冒充是一种虚假类型,涉及模仿者复现目标说话人的特定特征和说话风格。与通常会留下数字痕迹或信号伪影的TTS和VC不同,冒充涉及活生生的人类产生完全自然的语音,这使得冒充音频的检测成为一项具有挑战性的任务。因此,我们提出了一种新方法,将说话人画像(speaker profiles)集成到冒充音频检测过程中。说话人画像是模仿者难以准确模仿的固有特征,例如说话人的年龄、职业。我们旨在利用这些特征提取判别性信息以检测冒充音频。此外,目前没有大规模的冒充语音语料库可用于冒充影响的定量研究。为填补这一空白,我们进一步设计了第一个大规模、多说话人的中文冒充数据集,命名为ImPersonation Audio Detection(IPAD),以推动社区在冒充音频检测方面的研究。我们在所提出的IPAD数据集上评估了几种现有的虚假音频检测方法,证明了其必要性和面临的挑战。此外,我们的发现表明,融入说话人画像可以显著提升模型在检测冒充音频方面的性能。

英文摘要:

Fake audio detection is an emerging active topic. A growing number of literatures have aimed to detect fake utterance, which are mostly generated by Text-to-speech (TTS) or voice conversion (VC). However, countermeasures against impersonation remain an underexplored area. Impersonation is a fake type that involves an imitator replicating specific traits and speech style of a target speaker. Unlike TTS and VC, which often leave digital traces or signal artifacts, impersonation involves live human beings producing entirely natural speech, rendering the detection of impersonation audio a challenging task. Thus, we propose a novel method that integrates speaker profiles into the process of impersonation audio detection. Speaker profiles are inherent characteristics that are challenging for impersonators to mimic accurately, such as speaker's age, job. We aim to leverage these features to extract discriminative information for detecting impersonation audio. Moreover, there is no large impersonated speech corpora available for quantitative study of impersonation impacts. To address this gap, we further design the first large-scale, diverse-speaker Chinese impersonation dataset, named ImPersonation Audio Detection (IPAD), to advance the community's research on impersonation audio detection. We evaluate several existing fake audio detection methods on our proposed dataset IPAD, demonstrating its necessity and the challenges. Additionally, our findings reveal that incorporating speaker profiles can significantly enhance the model's performance in detecting impersonation audio.
