AI Video Translator
Key Features of AI Video Translator
Reach global audiences without re-recording.
Voice Preservation
Clones the original speaker's timbre and tone — the translated voice still sounds like them.
150+ Languages
HeyGen supports translation into 150+ languages and regional dialects. Twenty of the most-used are exposed here.
Speed and Precision Modes
Speed mode is faster and half the cost. Precision mode delivers higher-quality voice cloning and lip-sync.
Whole-Video Pipeline
Speech recognition, translation, voice cloning, and re-rendering — handled in a single API call.
Natural Phrasing
Advanced NLP keeps translations fluent and locale-appropriate instead of literal.
Commercial-Safe Output
