# Voice

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

1. Select **AI voice** in the Voice section.
2. Click **AI voiceover**.
3. In the **Voice over** panel, select a voice from the dropdown. Voices are available in multiple languages.
4. 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.
5. The script is rendered and used to generate the AI voiceover.

## 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.
