The Voice feature lets you control how audio is delivered in your video or interactive demo. You can keep the original audio, replace it with an AI-generated voiceover, or remove narration entirely. You can also add and manage subtitles from this section.
Voice options
In the Voice section, choose one of the following options:
| Option | Description |
|---|---|
| Original voice | Uses the original background audio from the recorded video or interactive demo |
| AI voice | Replaces the narration with an AI-generated voiceover |
| No voice | Removes all narration from the demo |
How to set up AI voiceover
- Select AI voice in the Voice section.
- Click AI voiceover.
- In the Voice over panel, select a voice from the dropdown. Voices are available in multiple languages.
- Under the Script section:
- If the demo already has subtitles, the voiceover is auto-generated from them. The generated script appears in the Script section, and you can edit it as needed.
- If there are no subtitles, click Add now to manually enter your narration script.
- The script is rendered and used to generate the AI voiceover.
How to add subtitles
- Click Subtitles in the Voice section.
- If the demo has a voiceover, auto-generated subtitles appear here. Edit them as needed.
- If there is no voiceover, manually enter your subtitle script.
- Enable the Display subtitles checkbox to show subtitles in the published demo.
NOTE
Subtitle editing is disabled when AI narration is turned on. Turn off AI narration to make changes to subtitles.

Best practices
- Use AI voice for consistency. AI voiceovers maintain the same tone and pace throughout the demo, unlike recorded audio which may vary.
- Always review the script before applying. Small errors in the script will carry through to the voiceover.
- Enable subtitles for accessibility. Subtitles help viewers follow along in noisy environments or when audio is unavailable.
- Edit auto-generated subtitles. Auto-generated subtitles may not always be perfectly accurate. Review and correct them before publishing.
- Turn off AI narration before editing subtitles. Subtitle editing is disabled while AI narration is active.
