What affects accuracy

  • Language — Use the groupings above as a guide. High-accuracy languages generally produce cleaner transcripts; fair-accuracy languages may need more review.

  • Audio quality — Clear audio (good microphones, less background noise, fewer overlaps) improves results in every language.

  • Code switching — If speakers switch languages during the same interview (for example English and Spanish in one conversation), transcription is less accurate than when the interview stays in a single language.

  • Regional variants — For widely used languages such as English, Spanish, French, and Portuguese, transcription generally understands common regional accents and variants.

Tips for multilingual interviews

  • Prefer a single primary language for the interview when you can.

  • If you must mix languages, expect more cleanup on the transcript and notes.

  • For languages in the fair or moderate bands, plan a quick human review before sharing feedback externally.
