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. 语音情感识别主要分析什么？
    • 声音的声学特征，如音调和能量
    • 文字记录中的字面意思
    • 句子的语法
    • 说话者的面部表情
  2. Which acoustic properties can speech-emotion models use as cues?
    • Only the spelling of transcribed words
    • Pitch, energy, speaking rate, and voice-quality features
    • A person’s job title
    • The number of speakers in a company
  3. 为什么标记情感数据特别困难？
    • 音频文件太大，无法存储
    • 麦克风无法记录情绪
    • 情感是主观的，人类注释者经常不同意
    • 情绪从来不会出现在言语中
  4. 以下哪一个是著名的情感语音数据集？
    • 图像网
    • 可可
    • 小队
    • IEMOCAP
  5. 现代 SER 系统通常如何利用有限的标记数据？
    • 通过微调像 wav2vec 2.0 这样的自监督模型
    • 通过完全避免神经网络
    • 仅使用手写规则
    • 首先录制数百万个新的情感片段
  6. What does the EU AI Act prohibit regarding emotion recognition?
    • All emotion-related research in any setting
    • Inferring emotions in workplace or educational settings, except for medical or safety reasons
    • Every voice assistant that detects speech
    • Any system that transcribes spoken words
  7. Why can a speech-emotion model trained on one dataset fail on another?
    • Emotion labels are identical across every corpus
    • Microphone and speaker differences never affect audio
    • Speakers, language, recording conditions, elicitation, and label distributions can differ
    • A trained model cannot process new recordings
  8. What is one limitation of treating a speech-emotion prediction as a person’s true internal state?
    • Acoustic features contain no information
    • A predicted label is a clinical diagnosis by default
    • The same voice always expresses the same emotion
    • A model infers patterns from audio and may not reflect the speaker’s context or self-report
