# Replace Product Demo Voiceover

Product demos are among the most-watched videos in any SaaS or e-commerce company, yet they often ship with a single voiceover that was rushed during the initial recording. When the product evolves, the script becomes outdated, and re-recording means coordinating with the original narrator or finding a new voice that matches.

AI dubbing solves this by letting you replace the voiceover with a new narration -- whether that means updating the script in the same language, switching to a different voice style, or translating into a new language entirely. The tool matches lip timing and pacing to the original video so the result feels natural.

This is especially valuable for product teams that ship frequent updates. Instead of re-recording demos from scratch every quarter, you update the script and let AI generate the new voiceover, keeping your demo library current without the overhead of studio production.
