Why you should use HeyGen’s AI dubbing tool
Fast, simple, and cost-effective
Need AI dubbing to create voiceovers and translate videos? Traditional dubbing requires studios, actors, and editors, making it costly and slow. With HeyGen, upload your video, choose from 175+ languages and dialects, and let AI generate professional dubs in minutes.
Preserve your unique voice
Generic text-to-speech flattens personality. HeyGen’s AI voice cloning captures your tone, style, and nuances, delivering audio that feels authentically you. Whether for marketing, training, or storytelling, your brand’s voice stays consistent across every language.
Seamless lip-sync accuracy
Nothing breaks immersion like off-beat dubbing. HeyGen’s AI aligns voiceovers precisely to speakers’ lip movements with advanced timing models. The result is smooth, natural synchronization that keeps viewers engaged.
Scale your global reach
Voice dubbing expands discoverability, watch time, and engagement. HeyGen automates high-volume localization so enterprises and creators can quickly translate entire libraries, attract international audiences, and accelerate growth.
Video and Audio Dubbing
HeyGen offers two dubbing engines: Speed and Precision. If you want context-aware translation with highly natural lip-sync and better gender detection, use the Precision model. If you want fast translations at scale, use the Speed engine.
You can also use audio dubbing to translate only the audio of a video—quickly and without applying lip-sync—for example, if there's no face in your video.
