Automatic Captioning

All VoiceThreads created after August 17, 2019 will be auto-captioned. VoiceThread will automatically add captions to your audio or video slides and comments using automatic speech recognition (ASR). The captioning processes begins as soon as you save your recording and should appear in 5-10 minutes, depending on the length of your recording. Captions are created based on the audio track and the content is assumed to be in English.

Captions are displayed beside the comment box.

In general, automatic captions average around 80% accuracy and this may vary depending on the audio quality, clarity of speech, background noise, etc. We recommend using the generated captions as a starting point - you will want to edit them for accuracy.

The Instant Captions with VoiceThread video will walk you VoiceThread's captioning features.
