AI Voiceover for Product Videos

What AI voiceover does

Narration turns a sequence of screens into an explanation. Without it, viewers have to work out what they’re looking at; with it, each scene has a reason to be there. Spotlight’s AI voiceover for product videos handles the parts that usually make narration hard: writing a script that fits the visuals, finding a voice that suits your brand, and mixing it properly.

The AI director writes the narration as it plans the film, using your Product Profile — audience, pain points, benefits and tone of voice — and what it sees in your screenshots and recordings. You choose a voice from a large library of natural voices from ElevenLabs. Music is ducked automatically under the voice, and the final mix is loudness-normalised to -14 LUFS, a common target for social platforms.

How it works

1. Build or pick a Product Profile from your URL. Its tone of voice guides the script.
2. Generate the first cut. The AI director writes narration scene by scene, matched to what’s on screen.
3. Choose a voice. Browse the library and preview voices against your own script.
4. Edit the words. Change any line yourself, or ask the AI to rewrite a scene (“shorter”, “less jargon”, “more confident”).
5. Add music and effects. Generate instrumental music from a brief, or upload your own track; add whooshes, clicks and pops where they help.
6. Export. Voice, music and effects are mixed, ducked and normalised in the 1080p MP4.

What you control

• Script — every line, in every scene.
• Voice — choose from a large library of natural voices.
• Music — AI-generated instrumental music from a written brief, or your own upload.
• Sound effects — synthesised whoosh, click, pop and more.
• Pacing — scene timing and the film’s overall pacing, so the visuals and narration line up.
• Captions — burned in, plus a downloadable .srt. See auto captions for product videos.

Who it’s for

Founders who don’t want to record their own voice, non-native speakers who want a clear read in English, product marketers who need consistent narration across a series of feature announcements, and agencies who need a different voice per client. It suits any launch where the viewer is likely to have sound on — YouTube, a landing page play button, an investor demo or a sales email.

Tips for better narration

• Write for the ear. Short sentences, one idea each. Read it aloud — if you run out of breath, split it.
• Don’t describe what’s obvious. “Here is the dashboard” wastes a line; “See every overdue invoice at a glance” earns it.
• Match voice to audience. A calm, measured voice for finance or health; a brighter one for consumer apps.
• Leave room to breathe. Let a zoom or result land before the next line starts.
• Check names and jargon. Listen for how the voice pronounces your product name and technical terms, and adjust the spelling in the script if needed.
• Plan for sound-off viewers too. On social, many people watch muted — keep captions on.
