A browser-based AI dubbing feature that translates videos into 140-plus languages using voice cloning and lip sync.
Synthesia AI Dubbing translates and dubs videos into more than 140 languages and dialects using AI voice cloning and lip synchronization. Users can upload MP4, MOV, and WebM files up to 4K resolution, paste a YouTube link, or record in the browser, and generate multiple languages from a single upload.
The feature captures each speaker's tone, emotion, and speaking style, keeps distinct voices across dubbed versions, and adjusts mouth movements to match the translated audio. It runs entirely in a web browser with a free tier and paid plans that remove watermarks and add higher usage, bulk dubbing, and API access.
