How to improve transcript accuracy

Automatically generated captions are never 100% accurate 100% of the time. This is because the accuracy of captions can vary according to audio quality, topic and speaker.

However, there are some simple steps you can take to improve the accuracy of your captions:

  1. Ensure you have a strong internet connection. Slow broadband can interrupt your live stream captioning and affect accuracy.
  2. Use an external USB microphone or wear a good-quality headset with a dedicated microphone arm rather than using the built-in microphone on your device. This can help reduce background noise, often leading to missing or incorrect words in your transcript.

 

If possible:

  1. Place your microphone in the middle of everyone who might be talking. For example, in the middle of a room rather than at one end.
  2. Minimise situations with echo and background noise. For example, choose to use an enclosed room rather than an open plan office and look for a smaller than bigger meeting room where possible.

Custom words

You can improve the accuracy of your transcript by adding words, phrases and acronyms to your Custom Dictionary. Follow our guide here to learn how to do this.

External Microphones 

Depending on the environment, your built-in microphone may not be the best for transcribing your sessions. For example, if you’re using Caption.Ed in a large lecture hall, it’d be best to use an external microphone for more accurate transcriptions.
