预览每个问题8 问题

当您参加测验时，就会出现答案和解释。

  1. 音频深度伪造检测器的核心目标是什么？
    • 判断语音是真实的还是人工智能合成的
    • 提高录音的音质
    • 将语音转录为文本
    • 压缩音频文件
  2. 在“音频 Deepfake 检测是否具有泛化性？”中，哪些特征比较提高了作者受控评估的性能？
    • Raw transcript tokens instead of audio
    • CQT or log-spectrogram features instead of mel-spectrogram features
    • A larger waveform file instead of a smaller one
    • Video frames instead of speech features
  3. 为什么音频深度伪造检测被描述为“军备竞赛”？
    • 探测器在军用硬件上运行
    • 音频文件不断变大
    • 新的合成方法可以避开接受过旧假货训练的检测器
    • 需要两个人操作
  4. 著名的 ASVspoof 基准测试评估什么？
    • 音乐推荐质量
    • 文本翻译准确率
    • 图像生成真实感
    • 语音反欺骗/深度伪造检测
  5. 有效的 C2PA 内容凭证可以帮助验证者检查什么？
    • A signed record of an asset’s provenance and edit history
    • That every spoken claim in the audio is true
    • The speaker’s real-world identity in all cases
    • That a recording has never been compressed
  6. What input type did the ASVspoof 2021 Deepfake task target?
    • Uncompressed music recordings from a studio
    • Manipulated, compressed speech posted online
    • Images altered by face-swapping systems
    • Only live telephone conversations with known speakers
  7. How large was the real-world dataset collected in the cited audio deepfake generalization study?
    • 3.79 hours total, all authentic speech
    • 37.9 hours of deepfakes with no authentic audio
    • 37.9 hours total, including 17.2 hours of deepfakes
    • 172 hours total, including 17.2 hours of deepfakes
  8. What does the absence of a C2PA credential establish?
    • That the recording is necessarily a deepfake
    • That the recording has no edits
    • That the speaker is verified
    • Nothing by itself about whether the media is authentic or synthetic
