AI Voiceover: Natural Narration with ElevenLabs | RemotionAI Blog
· 3 min read · Feature
Add professional AI-generated voiceovers to your videos. Multiple voice styles, character presets, and automatic timeline sync.
RemotionAI's AI voiceover feature uses ElevenLabs to generate natural-sounding narration that automatically syncs to your video timeline, with three character presets optimized for different content types. The integration works within the Remotion Claude video generation pipeline, eliminating the need for separate audio recording and manual alignment.
How it works
When you create a video with Remotion Claude, you can enable voiceover generation. The system takes your script or scene descriptions, sends them to ElevenLabs, and returns audio that gets automatically synced to your video timeline.
Voice presets
- Narrator — Clear, measured delivery. Good for explainers and educational content.
- Salesperson — Energetic, persuasive tone. Works for product demos and ads.
- Expert — Authoritative, calm. Fits well with technical or professional content.
Automatic scene sync
The voiceover isn't just a single audio file dropped on top of your video. The system generates audio per scene, matches the duration to your scene timing, and adjusts pacing so the narration doesn't feel rushed or drawn out.
If you edit your scenes after generating voiceover, you can regenerate individual scene audio without redoing the entire narration.
