How to Dub a Video Into Russian With AI and Keep Your Own Voice

You found a video in English, and you want to show it to your Russian-speaking audience in your own voice, with no subtitles and no dubbing studio. You used to call a translator, a voice actor, and a sound engineer, and a three-minute clip turned into a week-long project.

Now the whole path from the original to a finished Russian voiceover can be done with AI. I'll go through it step by step: how I translated and dubbed a clip with a clone of my own voice, and what in this process still has to be checked by hand.

What AI dubbing consists of

Dubbing a video into another language is made of three tasks in a row: get the exact text of the original, translate it while keeping the intonation and meaning, and voice the translation with a voice that sounds natural and fits the video. Each task used to be handled by a separate person. Now each can be closed by a separate tool, and what connects them is your editing in the middle.

Step 1: get the exact text of the original

If the video has no ready script, the text can be pulled out of the audio by speech recognition, for example with OpenAI's Whisper model, which sits under many transcription tools and services, including the open program Voicebox that I covered in a separate article. The result is the text of the original with timecodes showing where each phrase is spoken.

This step is worth checking by eye before translation. Speech recognition sometimes mixes up similar words or proper names, and a mistake in the text carries over into the translation and the voiceover.

Step 2: translate while keeping the intonation

A direct machine translation phrase for phrase often sounds wooden in voiceover: Russian sentences are longer or shorter than English ones, and the rhythm drifts away from the video. It's worth running the translated phrase through an AI with a request to keep a length close to the original and the meaning of the scene, not just the words.

For emotional scenes, specify the tone separately: a calm adult voice, an excited child's voice, a news announcer. The difference in how you word the request noticeably changes how the translated phrase will sit in the voiceover at the next step.

Step 3: clone the voice and voice the translation

For the voiceover itself you need a short sample of the voice, usually 10 to 15 seconds of clean recording with no noise or music, and a cloning program or service that synthesizes new speech from this sample. I use my voice clone for the adult line, and for the child's line in the same video I synthesized a child's voice separately, not my own.

If you need an open and free path with no subscription, in the article about Voicebox I covered exactly such a tool: voice cloning runs locally on your computer, with no monthly fee for minutes of voiceover.

Step 4: fit the voiceover to the length of the video

A translated phrase rarely lands in the video second for second. You need to either stretch or compress the voiceover a little in speed, or trim the pauses between phrases, so the line fits the scene without rough joins.

Here you need an AI tool that can stretch or compress speech and even out the pauses between phrases. It's a separate step after the voiceover and before the final assembly of the video.

Step 5: add word-by-word subtitles

Even with good voiceover, part of the audience watches videos without sound. Word-by-word subtitles, where each word is highlighted at the moment it is spoken, are built from the same speech recognition as in step 1, this time on the translated and voiced version.

Subtitles also hold the attention of people who finish the video on public transport or in a queue without headphones.

What honestly has to be checked by hand

The character's lips in the video move to the original speech, not to the dubbed one: none of these steps redraws the face for the new language. For short videos without a close-up of the face this is almost unnoticeable, but in a long interview with a face in the frame the mismatch will be visible.

Cloning someone else's voice without the consent of the person whose voice is copied is not acceptable. Technically the tool allows it, but the decision about whose voice to clone and for what stays with you. For your own voice and for fully synthetic characters, like the child's voice in my example, the question of consent doesn't arise.

And one last thing: the AI translation is worth rereading aloud before the final recording. Text that looks fine on the screen sometimes stumbles in pronunciation, and that is audible in the finished voiceover.

Bottom line

Translating and dubbing a video with AI takes one evening instead of a week with a studio and a dubbing actor. The text of the original, a translation that keeps the rhythm, a voice clone, fitting to length, and word-by-word subtitles: each step is closed by a separate free or nearly free tool, and only your editing in the middle connects them.
