Add AI Voiceover to Your Ads Inside Claude | Polaris

To add voiceover to an AI ad, stay in the same Claude chat where Polaris is connected, ask for a voiceover track over your script or existing ad, and confirm the voice settings on the tappable option cards - Polaris generates the narration through ElevenLabs and shows it rendering live in the conversation panel.

Why voiceover changes how an ad lands

A script read well can carry an ad even when the visuals are simple, and a mismatched or robotic voice can undercut a strong script. Because Polaris generates voiceover through ElevenLabs as part of the same workflow used for video and image generation, you are not exporting a script to a separate tool, recording narration, and re-importing audio - the voiceover step happens in the same chat as everything else.

Step-by-step: adding voiceover in Claude

1. With the Polaris MCP connector active in Claude, share your script or point to the ad that needs narration.
2. Ask Claude to generate a voiceover for the script, or to add one to an ad you already rendered.
3. Answer the voice and delivery questions Claude asks via the tappable option cards - these cover things like tone and pacing rather than raw technical parameters.
4. Let Polaris render the voiceover. The live panel in the conversation shows progress and plays back the finished track.
5. If the ad needs burned-in captions to match the narration, request those with one click in the same chat.
6. Review the finished ad with voiceover in place, and ask for a re-render with adjusted pacing or tone if something feels off before you move on.

Pro tips

• Write the script for the ear, not the eye - short sentences and natural pauses read better as spoken narration than dense written copy does.
• Time the voiceover to the visual beats: the line that mentions the product should land when the product is on screen, not a beat later.
• Run the script through Copy Judge before generating voiceover, so you are narrating copy that already scores well rather than fixing it after the fact.
• Batch a couple of tone variants (energetic versus conversational) for the same script when you are unsure which delivery fits your audience.

Honest caveats

Voiceover generation speeds up production, but it does not replace testing - a narrated ad still needs to prove itself against real audience results, not just sound good in the panel. If your product sits in a regulated category, the script behind the voiceover needs the same compliance discipline as any other ad copy: no disease or cure claims, no guaranteed-result language, no matter how convincing the delivery sounds. And because Polaris pairs an AI actor's voice with your script rather than cloning a specific real person, expect a generated narration voice, not an impersonation of anyone.
