Using closed captioning

You can add closed captioning to any video or audio slide, or to any video or audio comment.

How to add a caption to VoiceThread

Only the person who created a VoiceThread or someone who has editing rights for that VoiceThread may add captions. Get started by accessing the caption dialog for your slide or comment.

For central media slides:

  1. Navigate to the slide that contains the video.
  2. Hover your mouse over the video icon on the left side of the page.
  3. Click on the CC button in the top-right corner of the VoiceThread.

  6. Click “OK”.

For comments:

  1. Start playing the comment.
  2. Click on the CC button at the bottom of the comment.

  3. Select your caption file.
  4. Click “OK”.

This will open the caption dialog box, where you can upload or request your caption. If you are uploading a file manually, just click on “Upload Captions” on this dialog and upload your file.

VoiceThread accepts caption files in these formats:

  • DFXP
  • SRT
  • SAMI
  • SCC
  • SBV

Professional caption integration

If your institution has a license with 3Play Media, Amara, Automatic Sync, Cielo24, or Verbit, then you can integrate that license with VoiceThread to enable one-click professional captioning. If this option is available to you, then you will see the option to use a Transcription Service in the caption dialog. Simply select the priority level from the menu (if available), and then click on the green arrow next to the caption service you want to use. Your slide or comment will be captioned automatically as soon as your caption provider completes the request.

Note that wait times may vary from several hours to several days depending on the service.  While the caption file is processing, you’ll see a clock icon next to the caption service in this interface.  Once the caption is complete, you’ll see a check mark instead. You will also receive an email notification from VoiceThread once the caption is available to view.

Viewing captions in VoiceThread

Captions will always be displayed when you are viewing a VoiceThread slide at VT Universal. If you’re viewing the slide from the standard VoiceThread site, turn on closed captioning by clicking on the “CC” button in the top-right corner of the VoiceThread, and selecting “On”. Any slide or comment that has been captioned will display those captions as long as this option is on.


Altering a caption

Once a caption has been added to a slide or comment in VoiceThread, you can always remove or download that raw caption file. To do that, see the instructions above to access the caption dialog.  If you see the “Download captions” and “Remove captions” buttons, that means a caption file already exists for this media. Click those buttons to download or remove the caption files if needed.

Captions cannot be edited directly in VoiceThread, but you can download a caption file, make changes by hand in a text editor, and then re-upload that same file into VoiceThread.
