摘要翻译：
语音转换(VC)的目的是在不改变内容的情况下转换说话人的特征。由于训练数据的限制和建模的不完善，在不引入处理伪影的情况下很难实现可信的说话人模仿；因此，虚拟语言的性能评估通常包括说话人相似度和人面板的质量评估。作为一个耗时、昂贵、不可复制的过程，它阻碍了新的VC技术的快速成型。我们使用一种替代的、客观的方法来解决伪影评估问题，该方法借鉴了先前关于自动说话人验证的欺骗对策(CMs)的工作。其中，CMs被用于拒绝“假”输入，如重放、合成或转换语音，但其自动语音伪影评估的潜力仍然未知。这项研究填补了这一空白。作为对2018年语音转换挑战赛(VCC'18)数据主观结果的补充，我们配置了一个标准常数q倒谱系数CM来量化处理伪影的程度。CM的等错误率(EER)是VC样本与真人语音的易混淆性指标，是我们的伪影度量指标。识别出VCC'18条目的两个簇：具有可检测伪影的低质量条目（低EERs）和具有较少伪影的高质量条目。然而，没有一个VCC'18系统是完美的：所有的EER都<30%(`理想‘值是50%）。我们的初步发现表明，CMs在其原始应用之外的潜力，作为一种补充优化和基准工具，以增强VC技术。

英文摘要：
  Voice conversion (VC) aims at conversion of speaker characteristic without altering content. Due to training data limitations and modeling imperfections, it is difficult to achieve believable speaker mimicry without introducing processing artifacts; performance assessment of VC, therefore, usually involves both speaker similarity and quality evaluation by a human panel. As a time-consuming, expensive, and non-reproducible process, it hinders rapid prototyping of new VC technology. We address artifact assessment using an alternative, objective approach leveraging from prior work on spoofing countermeasures (CMs) for automatic speaker verification. Therein, CMs are used for rejecting `fake' inputs such as replayed, synthetic or converted speech but their potential for automatic speech artifact assessment remains unknown. This study serves to fill that gap. As a supplement to subjective results for the 2018 Voice Conversion Challenge (VCC'18) data, we configure a standard constant-Q cepstral coefficient CM to quantify the extent of processing artifacts. Equal error rate (EER) of the CM, a confusability index of VC samples with real human speech, serves as our artifact measure. Two clusters of VCC'18 entries are identified: low-quality ones with detectable artifacts (low EERs), and higher quality ones with less artifacts. None of the VCC'18 systems, however, is perfect: all EERs are < 30 % (the `ideal' value would be 50 %). Our preliminary findings suggest potential of CMs outside of their original application, as a supplemental optimization and benchmarking tool to enhance VC technology.
