摘要:

所有现有的欺骗性语音数据库都包含完全欺骗的攻击数据。在实践中,成功的攻击完全可以通过仅部分欺骗的话语来实现。根据定义,部分欺骗的话语包含欺骗和真实片段的混合,这可能会降低用完全欺骗的话语训练的对策的性能。这个假设提出了一个显而易见的问题:“我们能检测到部分欺骗的音频吗?”“本文介绍了一个名为PartialSpoof的新的部分欺骗数据数据库,以帮助解决这个问题。这个新的数据库,使我们能够调查和比较的性能的对策话语和段级标签。使用话语级标签的实验结果表明,被训练用于检测完全欺骗数据的对策的可靠性被发现在用部分欺骗数据进行测试时大幅降低,而在完全和部分欺骗话语的情况下,对部分欺骗数据的训练可靠地执行。使用段级标签的附加实验表明,即使使用最新的对策模型,发现话语中包含的注入的欺骗段也是一项更具挑战性的任务。

英文摘要:

All existing databases of spoofed speech contain attack data that is spoofed in its entirety. In practice, it is entirely plausible that successful attacks can be mounted with utterances that are only partially spoofed. By definition, partially-spoofed utterances contain a mix of both spoofed and bona fide segments, which will likely degrade the performance of countermeasures trained with entirely spoofed utterances. This hypothesis raises the obvious question: 'Can we detect partially-spoofed audio?' This paper introduces a new database of partially-spoofed data, named PartialSpoof, to help address this question. This new database enables us to investigate and compare the performance of countermeasures on both utterance- and segmental- level labels. Experimental results using the utterance-level labels reveal that the reliability of countermeasures trained to detect fully-spoofed data is found to degrade substantially when tested with partially-spoofed data, whereas training on partially-spoofed data performs reliably in the case of both fully- and partially-spoofed utterances. Additional experiments using segmental-level labels show that spotting injected spoofed segments included in an utterance is a much more challenging task even if the latest countermeasure models are used.
