Narration

AI narration generates a voiceover from your course text. Turn it on, pick a voice, review the scripts, then generate the audio when you publish.

AI narration automatically generates a high-quality voiceover for your course content, so learners can listen as well as read. You turn it on, choose a voice, review the narration script for each screen, and the audio is generated when you publish. Generating narration uses tokens from your monthly narration allowance.

Turn on narration

1. Open the course and select the Narration icon at the top of the screen.
2. Toggle on Use Narration.
3. Choose your voice, and adjust the autoplay and progress settings. The narration language is set automatically from the language your course is written in, so there's nothing to select there.
4. Select Save changes. If you don't save, narration won't stay on and you won't be able to generate audio.

Review the narration scripts

By default, narration reads the on-screen text. If you want the narration to differ from what's on screen:

1. Open a screen and select the Narration settings icon.
2. Toggle off Sync narration with screen.
3. Edit the narration script for that screen, and repeat for any others.

Reviewing scripts before generating avoids using tokens on audio you'll redo.

Generate the narration

Narration is generated when you publish:

1. Select Publish, then toggle on Generate narrations.
2. The dialog shows how many narrations will be generated and your token balance.
3. Select Generate narrations and publish.

Generate narration only once your course is finalised, to make the best use of your tokens.

Choose and preview a voice

In Course settings, then Narration, choose from the voices available on your plan. The narration language matches your course automatically, so you're choosing a voice within that language. Select the speaker icon next to a voice to hear a sample. Changing the voice after generating means publishing again to regenerate the audio.

Autoplay and listening settings

• Autoplay: narration starts automatically when a learner lands on a screen (except the first screen, which most browsers block until the learner interacts).
• Require learners to listen in full: learners can't move on until the narration finishes, which keeps them on each screen for its full audio.

The learner experience

When narration is on, learners see a speech-bubble icon in the bottom-right. They can pause and resume narration, and adjust playback speed while it plays.

Narration tokens

Narration uses tokens from your monthly allowance, which is why you generate audio at publish time rather than on every edit. The publish dialog shows how many narrations will be generated and your current token balance before you commit, and each language in a translated course is narrated separately. To make the best use of your allowance, finalise your course content and review your scripts before generating.

Frequently asked questions

Can I change the narration language?

No. The language is detected automatically from the language your course is written in. You choose a voice within that language rather than setting the language yourself.

Do edits use tokens?

Tokens are only used when you generate or regenerate audio by publishing. Editing scripts or changing settings like autoplay won't use tokens until you publish.

Can I edit a narration script after generating?

Yes. Edit the script any time, then publish again to regenerate that screen's narration, which uses additional tokens.
