Vaani

Dub videos into lip-synced, voice-matched multilingual versions.

What is Vaani? Vaani focuses on AI video dubbing that keeps the creator’s own voice, timing, and on-camera presence while translating content into 40+ languages. It combines neural voice cloning, machine translation, and visual lip-sync models so creators, brands, and studios can localize videos far faster and cheaper than traditional dubbing, without ending up with robotic, off-beat audio. Key Features: Voice-preserving multilingual dubbing: Clones the original speaker’s voice and re-generates it in dozens of target languages while retaining tone, style, and personality. Frame-accurate lip sync: Uses computer vision to align translated speech with mouth movements and shot timing so lips, pauses, and expressions feel native. Browser-based studio editor: Offers a timeline-style interface to review the AI pass, tweak segments, adjust timing, and approve each language before export. Music and ambience preservation: Separates dialogue from background elements so localized lines can be swapped in while keeping the original soundtrack and sound design intact. Pros Natural feel vs “robot dub”: Output aims to sound like the actual creator speaking other languages, not a generic text-to-speech narrator. Big time and cost savings: Shortens localization cycles from weeks to days or hours while avoiding studio bookings and multi-voice casting.
