  1. Qual tecnologia central converte fala ao vivo em texto na tela?
    • Reconhecimento automático de fala (ASR)
    • Reconhecimento óptico de caracteres (OCR)
    • Conversão de texto para fala (TTS)
    • Posicionamento global (GPS)
  2. What distinguishes CART captioning from automatic speech-recognition captions?
    • It requires no human input
    • A trained human captioner uses stenotype, a computer, and realtime software
    • It translates every caption into another language automatically
    • It is a word-error-rate formula
  3. Why can words in a streaming caption change before an utterance is finalized?
    • The caption file has become an image
    • A speaker label always changes the language
    • The recognizer can emit intermediate hypotheses that change as more audio is processed
    • The final transcript is guaranteed to contain no errors
  4. Qual métrica é comumente usada para medir a precisão das legendas?
    • Quadros por segundo
    • Decibéis
    • Pixels por polegada
    • Taxa de erro de palavras (WER)
  5. What does speaker diarization add to a live transcription workflow?
    • Labels that distinguish speech from different speakers, without verifying their real-world identities
    • Automatic translation into every language
    • A guarantee of correct word recognition
    • A replacement for microphone audio
  6. What caption capability did Meta describe for Ray-Ban Display glasses?
    • Guaranteeing perfect recognition in noisy rooms
    • Displaying captions for speech directed at the wearer
    • Replacing caption standards for every video
    • Automatically identifying every speaker in a meeting
  7. What do captions for accessibility often include besides spoken dialogue?
    • Only the video title
    • A guarantee of perfect transcription
    • Relevant non-speech audio information such as sound effects or speaker cues
    • The model’s confidence score only
  8. Which caption file format does W3C identify as the most common on the web?
    • CSV
    • PNG
    • MP3
    • WebVTT
