  1. A transcript has four substitutions, three deletions, and two insertions against a 100-word reference. What is its word error rate?
    • 9%
    • 4%
    • 7%
    • 100%
  2. Why inspect individual transcript errors after calculating word error rate?
    • The score identifies speaker identity
    • The aggregate does not show whether an error changed a key instruction
    • The percentage verifies punctuation
    • The number proves accent fairness
  3. A recording contains overlapping speakers and unusual names. What does the guide recommend?
    • Treat speaker labels as verified identity
    • Assume one dataset score applies to the recording
    • Expect recognition challenges and review names and uncertain passages
    • Remove the original audio
  4. A transcript labels two speakers. What does a speaker label establish?
    • It shows that translation is correct
    • It proves who spoke
    • It guarantees transcription accuracy
    • It is a model output, not necessarily a verified identity
  5. Why preserve the original recording and timestamps where permitted?
    • They automatically correct word error rate
    • They let reviewers check uncertain transcript passages against the source
    • They replace the transcript reference
    • They guarantee that no words were omitted
  6. Which error types does word error rate count?
    • Speaker changes and audio duration
    • Only punctuation and capitalization
    • Substitutions, deletions, and insertions
    • Translation and summarization errors
  7. Why report normalization rules with a WER score?
    • Punctuation, casing, and tokenization choices affect the result
    • Normalization verifies who spoke
    • Rules remove all semantic errors
    • It makes all datasets comparable automatically
  8. A system transcribes silence as confident words. What does the guide suggest testing?
    • Speaker identity accuracy
    • Only clean speech from one speaker
    • Translation quality
    • Silence and non-speech audio
