How is an accuracy rate typically measured in QA for transcripts?

• A. Count the number of words in the transcript.
• B. Rely on editor's intuition.
• C. Based on viewer satisfaction.
• D. Compare transcript text to audio/video against a ground truth, calculating errors per word/line and overall percent accuracy.

Answer: (D)

Measuring accuracy rate in QA for transcripts focuses on how closely the produced transcript matches a trusted reference. The standard method is to compare the transcript against a ground truth aligned to the same audio or video, then count the errors at the word level—substitutions, deletions, and insertions. From that, you compute the overall percent accuracy, often expressed as a word error rate, where accuracy equals 100% minus the error rate (or correct words divided by total words). This objective, auditable comparison can also be broken down per line if needed. Relying on editor intuition, simply counting words, or aiming for viewer satisfaction doesn’t provide a precise, reproducible measure of transcription correctness.
