Set yourself up for good quality audio and optimum accuracy

 

The better the quality of your audio file, the better the accuracy of your transcript. So we recommend using your free 15 minute trial to test your file for audio quality. The level of accuracy of your transcribed file is dependent upon a number of influencing factors, and here are some tips to help improve your transcription accuracy:

 
Equipment:
  • Record on a high-quality device at a high bitrate – we recommend 256 kbit/s or better
  • Record as directly as possible, e.g. record a computer video call directly on the computer, not with a mobile phone beside the speaker
  • Place the microphone close to speakers – distant voices are hard to detect

 

When you record:
  • If possible, limit the number of speakers and ask them to speak slowly, clearly and one at a time
  • Try to ensure that only one language is spoken – when you submit the audio for transcription you can select only one language to guide the automated transcription
  • Try to maintain a consistent volume level without long pauses
  • Minimize background noise
  • Be aware that strong accents and multiple accents can reduce accuracy e.g. mixed Australian and American accents may give less accurate results than only Australian or American accents
  • Be aware that slang expressions may not be recognized in the automatic transcription
  • Ensure audio files are no longer than 4 hours and no more than 4GB in size
“NVivo Transcription is a ‘must-have’ for any qualitative academic.  As a Caribbean researcher, I was very impressed that the tool was able to transcribe my interviews with a high level of accuracy despite our different dialects and accents. The time savings are immeasurable and it’s user-friendly. It will also save me a lot of money.”
