AI dubbing & speech translation

Translate spoken video or audio into other languages, keeping the voices.

What it is

Dubbing APIs transcribe the speech in a video or audio file, translate it, and re-speak it in another language, usually keeping each speaker's voice and the background music. Some also re-sync lips to the new language. It replaces a studio dubbing workflow with an automated pipeline.

How pricing works

Billed per minute of source media, and the price is usually per target language (translating into 3 languages is 3 times the cost). Premium tiers add voice cloning, lip-sync or human review. We normalise to one minute of source into one target language.

We compare everything in one unit: USD per minute of source video.

Watch out for

Per-language billing multiplies quickly; check whether the quote is per language.
Machine translation of idioms and brand terms still needs a human check for public content.
Watermarks or lower tiers may apply on cheaper plans.

Capabilities explained

Languages: Number of languages the service handles. More is better only if your target languages are on the list; check them individually.
Keeps original voices: Dubbed speech is cloned from the original speakers, so people still sound like themselves.
Lip-sync: The video is re-timed so mouths match the translated speech.
Multiple speakers: Detects and dubs several speakers separately in the same file.
Edit transcript before render: You can fix the translation or timing before the final audio is generated.
Commercial use allowed: Whether outputs may be used in a commercial product under the provider's terms. Always re-check the license for your case.

Glossary

Voice-preserving dub: The translated speech sounds like the original speaker, not a generic voice.
Lip-sync: Adjusting mouth movement so it matches the dubbed audio.
Speaker diarization: Working out who is speaking when, so each person gets their own voice.
