AI Dubbing: One Voice Across 30+ Languages Fish Audio

Dubbing is two problems wearing one coat: language and voice. Most tools solve the language and replace the voice, which is why so much dubbed content sounds like a different channel. Here the voice is the part that stays: you transcribe the original audio, translate the script, and regenerate it in the same cloned voice, in any of 30+ languages.

What follows is the honest version of that workflow — including the step this platform does not do for you.

How does the workflow fit together?

Four stages, two of them yours:

1. Transcribe. Run the original audio through speech to text. You get the transcript with speaker separation and emotion tags, which is also your timing map.
2. Translate. Translate the transcript in your translation tool or with a translator. This is the step outside this platform, and it is worth doing well — machine translation that reads fine silently can fall apart spoken.
3. Re-voice. Generate the translated script with the same cloned voice, language set per clip. One voice, many languages, consistent character.
4. Re-time. Lay the new audio against the original video in your editor. Adjust pauses and split sentences where timing drifts.

The first and third stages are the engine here; the middle one stays with you on purpose. A translation you control is a translation you can fix.

Why keep the same voice?

Voice is identity. Three cases where that matters most:

• Creator content. Your audience follows your voice. Dubbed versions should sound like you speaking Spanish, not like a different narrator reading your script.
• Brand and product videos. A spokesperson or a founder voice clone carries the brand register across markets without re-recording days of studio time per language.
• Series and characters. Characters keep their voice across locales, the same principle the character voices guide applies within one language.

A voice here is not locked to the language it came from. That is what makes the same-voice promise possible at all; most dubbing pipelines have to choose between a consistent character and a native-sounding delivery in every market.

What about pacing and lip sync?

Two realities to plan around:

• Pacing drifts by language. Spanish runs longer than English for the same sentence; Japanese often shorter. Budget your timing in the edit, keep sentences short in the source script, and expect to trim silence rather than stretch speech.
• Lip sync is a video problem. The audio tracks here will not match mouth shapes on close-ups. For talking-head footage either re-edit cutaways over the mismatched sections, or bring in a dedicated lip-sync tool after generation. For narration-over-b-roll — the majority of dubbing work — this never comes up.

The voice over guide covers delivery and pacing control in more depth; dubbing inherits all of it.

What does a dubbing project cost?

Audio scales linearly with minutes and languages:

One credit is roughly a minute of finished speech. Transcription for the first stage adds a comparable order of magnitude to the total. Against the packs: a five-language 10 minute series of 8 episodes lands near 360 credits, which fits inside the $29 Creator pack — and the $99 Studio pack adds API access if your pipeline generates programmatically.

Commercial use of the output, including client dubbing work, requires the commercial rights that start with Creator. If the original voice is not yours, add the voice rights checklist to the project plan before generation begins: consent first, cloning second.

What does a quality-control pass look like?

Before a dubbed video ships, check the four things that actually break:

1. Names and numbers. Order IDs, currencies, and place names audibly, not just in writing.
2. Idioms. Flag anything a literal translation would smuggle through; have a native speaker scan the script, not the output.
3. Emotion tags. Confirm the [excited] and [whispering] tags survived translation — mood is the first thing a hurried translation flattens.
4. Trim points. Listen where the audio meets the original's timing anchors: intros, on-screen text, music drops.

Frequently asked questions

Can I dub a video and keep the original voice?

Yes, for voices you have the rights to. Clone the voice from a 15 second sample, then generate the translated script in that same voice. The audience hears one consistent voice in every language.

Is dubbing one click here?

No, and this page does not pretend otherwise. Transcription and generation happen here; translation and re-timing happen in your own tools. The middle steps stay yours on purpose.

How much does dubbing a 10 minute video cost?

Roughly 9 credits per language for a 10 minute video, so five languages lands near 45 credits — under 5% of the $9 Starter pack. Transcription adds a comparable order of magnitude.

Does it handle lip sync?

No. Generation produces the audio track; matching mouth shapes is a video-editing step, and close-up lip sync may need a dedicated video tool. Narration-style dubbing, where the original speaker is off camera, works directly.

Do I need commercial rights to dub client videos?

Yes. Commercial usage rights start with the $29 Creator pack. If the original voice belongs to someone else, you also need their permission to clone and reuse it.
