Viewing captions and trascripts

While viewing a VoiceThread, turn on closed captioning by clicking on the “CC” button in the bottom-right corner of the VoiceThread and selecting the language of the caption you want to view.

To find a transcript of a slide or comment, click on the “CC” button in the bottom-right corner of the VoiceThread for a slide and select “Edit Captions,” or inside the comment window for a comment. The transcript will display on the right side of the window.

How to add a caption file to a slide or comment

Only the person who created a VoiceThread or someone who has editing rights to that VoiceThread can add captions.

3. Select “Add caption file” from the menu.
4. Click “Captions” beneath the slide media, and select “Add caption file.”
5. Click “Upload captions,” and select the CC file you want to use.
6. Close the caption window when you’re done.

For comments:

1. Start playing the comment you want to caption.
2. Click on the CC button near the bottom-right corner of the comment window.
3. Click “Captions” beneath the slide media, and select “Add caption file.”

VoiceThread accepts caption files in these formats:

• DFXP

Requesting free captions

VoiceThread currently offers machine-generated captions at no cost. To request free machine captions, use the steps above to add a caption, but choose “Order captions” next to the option labeled “Machine captions from VoiceThread” option instead of uploading a file.

There is a 4-day turnaround time, and you will receive an email notification as soon as the caption is ready to be viewed. This option will be guaranteed free through December 31, 2023, and we will evaluate whether we can continue to keep it free at that time.

Professional caption integration

If your institution has a license with 3Play Media or AutomaticSync Technologies, then you can integrate that license with VoiceThread to enable one-click professional captioning. To request captions from your third party provider, use the steps above to add a caption, and choose “Order captions” next to your provider’s name.

Your slide or comment will be captioned automatically as soon as your caption provider completes the request.

Automatic VoiceThread Captioning

If your institution has purchased Platinum Service, then every audio or video recording you create in VoiceThread will be captioned automatically. You don’t need to do anything at all to initiate the process. As soon as you save your recording, the captioning process will begin. Captions should appear in 5 to 10 minutes, depending on the length of your recording.

Note that the automatic captions use machine captioning technology, so there may be minor errors. Scroll down to see how to edit captions.

Contact us if you would like to upgrade in order to have access to automatic captioning.

Editing captions

Once a caption has been added to a slide or comment in VoiceThread, you can always edit it to make changes or correct any mistakes.

1. Open the caption window for a slide or comment using the steps above.
2. Click on the “Captions” button beneath the media preview, and select “Edit captions.”
3. Make any changes using the text chunks on the right.
4. Save.

If you want to delete a caption file altogether, click on the menu icon in the top-right corner, and select “Delete caption file.”
