Automatic Captioning

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.

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.

View Captions

While viewing a VoiceThread, turn on closed captioning by clicking on the “CC” button in the bottom-right corner of the VoiceThread and selecting English. Currently all VoiceThread captions are in English.

Once turned on, all captions will display along the bottom of the slide.
