What Is AI Dubbing?
AI dubbing takes a video in one language and recreates it in another — using the speaker's own cloned voice. The AI transcribes, translates, generates speech, and syncs the lips to match.
The result: a video that looks and sounds like it was originally recorded in the target language. No actors, no studio, no weeks of post-production.

Quick picks
If you are translating real footage for business use, start with Dubly.AI's free trial — one short video, no credit card. If you need avatars, start with HeyGen. For everything in between, the cards below.
Lip-sync score, glossary, review by your own native speakers, DPA
Limitation: Not the right choice if you need a free plan or more than 40+ target languages — HeyGen covers 175+.
Runner-up: VEED
Servers in Germany, no AI training, DPA
Limitation: From €89/month with no free plan — Synthesia starts at €26 and VEED at €22 if EU hosting is your only requirement.
Runner-up: Synthesia, VEED
Entry price $29/month; Dubly.AI starts at €89
Limitation: Not the right choice if lip sync has to hold up on close-ups: 50.4 / 100 in the independent benchmark, and lip sync costs extra points on top of dubbing.
Runner-up: HeyGen, Rask AI
Dubly.AI creates no avatars
Limitation: Not the right choice for dubbing recorded footage: 76.8 / 100 in the independent lip-sync benchmark, US servers, and AI training that is opt-out rather than excluded.
Runner-up: Synthesia
No lip sync needed, voice quality
Limitation: No lip sync inside Dubbing — the speaker's mouth keeps moving in the original language, so this is not the pick for talking-head video.
Runner-up: Rask AI

Learn the Basics
AI dubbing is the process of using artificial intelligence to automatically translate and re-voice video content into different languages, replacing the original audio track with a synthesized voice that matches the speaker's tone and cadence.
Core TechnologyAI lip sync is a technology that uses deep learning to modify a speaker's visible mouth and facial movements in video footage so they match audio spoken in a different language, creating the appearance that the speaker is naturally speaking the dubbed language.
Core TechnologyVoice cloning is an AI technique that creates a synthetic replica of a specific person's voice, preserving their unique tone, pitch, cadence, and speaking style. In the context of video dubbing, it allows translated audio to sound like the original speaker rather than a generic text-to-speech voice.
