本文报告了一些试图欺骗最先进的说话人验证(SV)系统的方法。为了评估SV系统中的风险，必须考虑到知道他们正在攻击谁的可能的故意冒名顶替者。我们定义了一种最坏的情况，其中冒名顶替者对要欺骗的人以及要攻击的系统有广泛的了解。在这个框架中，我们针对串接的客户语音、客户语音的重新合成和客户的双音素合成对我们的SV系统进行了测试。
This paper reports on some ways to try to deceive a state-of-the-art speaker verification (SV) system. In order to evaluate the risk in SV systems one has to take into account the possible intentional impostors who know whom they are attacking. We defined a worst case scenario where the impostor has extensive knowledge about the person to deceive as well as the system to attack. In this framework we tested our SV system against concatenated client speech, re-synthesis of the client speech and diphone synthesis of the client.
