Adding voice-overs to existing courses can be a great way to turn your course into a self-contained, unique instructional asset.

You can insert one voice-over per page/question. Click the Add voice-over button and upload the audio, record it directly from our tool, or use the Text-to-Speech functionality.

NOTE: Autoplay may be disabled in some browsers (like Safari) by default. For a voice-over to start playing, a learner has to click the Play button.

Supported audio formats are:

.aif
.au
.mp3
.ogg
.wav

If your audio has a different format, you can convert it to one of the supported formats using free online tools such as media.io, Online Audio Converter, etc.
​
​NOTE: Voice-overs are not available on iOS devices due to the auto-play restrictions in this system.
