Speech recognition, translation, voice synthesis and timing — Spimov's AI handles the full pipeline automatically.
Spimov is an AI video dubbing platform: you upload a video, and it transcribes the speech, produces a context-aware translation and re-voices it in a cloned version of the original speaker — in any of 600+ languages. Background music and sound effects are separated and kept, lip movement can optionally be reshaped to match the new audio, and editable subtitles come out of the same job.
What makes a dub work isn't only the words. Spimov references the tone and emotion of the original delivery, so a laugh, a pause or a raised voice carries into the new language. In a multi-speaker video each speaker is separated and cloned individually, so voices never blend together.
The output is a draft you control, not a black box. Every line is there as text: you can correct a name, tighten a sentence and re-voice only that segment instead of reprocessing the whole video. Creators use it to grow international audiences, course platforms to localise lessons, and film, series and documentary producers to open a finished production to new markets.

What a studio schedules in weeks runs as a single GPU-accelerated job.
Spanish, German, French, Arabic, Japanese, Chinese and hundreds more — several from one upload.
The dub references the original delivery, so a line keeps the same weight in the new language.
Open a finished feature to new markets without a new shoot, and hand a distributor a sample language version.
Keep character voices identical across a season with saved voice profiles, and deliver episode by episode.
Carry the narrator's tone into other languages and build a multilingual set for festival and platform submissions.
Localise lessons and field training; completion rises when learners don't have to read while watching.
Publish the same clip in several languages, with subtitles from the same job for silent autoplay.
Subtitles are cheaper, faster and often enough. In short social video, where most viewing happens on silent autoplay, they can outperform a dub. They also leave the original performance untouched, which matters when the voice itself is the point.
Dubbing wins wherever the viewer's eyes are busy or the content is long. In lessons, field training and documentaries, making the audience read while watching lowers completion. In drama, a dub removes the screen between the viewer and the performance.
You don't have to choose: Spimov produces subtitles from the same job as the dub, so you can publish both and let each platform use what fits.
We don't claim AI dubbing is identical to a studio dub. A dubbing director, casting and repeated takes add a layer of interpretation a model doesn't reproduce. What Spimov does is carry the original delivery's tone and emotion into the new language, quickly and across many languages at once.
Some material is harder than others: heavy background noise, overlapping speech, songs and thick accents all reduce quality. Lip sync is at its best on frontal, well-lit faces and weakens at extreme angles. We'd rather say that up front than have you discover it on a deadline.
That's also why every account starts on a free plan. Run a representative two- or three-minute section of your own material and listen to it next to the original — that judgement is worth more than any sentence on this page.
The chain runs like this: speech is separated from music and effects, transcribed into a timestamped script with speakers identified; the script is translated into the target language; it is re-voiced in each speaker's cloned voice; the audio is aligned to the original line's timing; and lip movement is optionally reshaped to match. It all runs as a single job.
You can upload MP4, MOV, MKV, WEBM and M4V. The free plan processes short videos; feature-length and episode-length content is supported on paid plans. Current duration and file size limits are listed on the pricing page.
Yes, if you use voice cloning. The system references the speaker's vocal character and generates the new language's sentences in that same voice. Make sure you have permission before cloning someone else's voice — you can also pick a ready-made library voice.
Yes. The free plan lets you upload a short section and listen to the result with no credit card. Free output carries a watermark and has a length limit.
MP4, MOV, MKV, WEBM or M4V.
Transcription, translation, voice cloning and timing happen automatically.
