AI Video Dubbing on Mac: Speak Other Languages in Your Own Voice
Translate what you say in a video into one of 23 languages and hear it spoken in your own voice. Creavit Studio translates the captions along with it and places the dubbed takes on the timeline. The voice engine runs on your Mac, and only your own voice can be used.

How Dubbing Works in the Voice Tab
Captions, translation, your voice and the timeline — in one run from the editor.
01
Your Voice, Another Language
The Voice tab translates the speech in your video and speaks the translation in your own voice. Each line becomes a voice take on the timeline, sped up where it needs to fit the original timing.
02
23 Languages
Arabic, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese, Russian, Spanish, Swahili, Swedish and Turkish.
03
Captions Translated Too
The captions switch to the target language in the same run and are timed to the dubbed voice, so the subtitles match what viewers hear.
04
Runs on Your Mac
The voice engine is Chatterbox Multilingual by Resemble AI (MIT license). It is installed on demand — about 4 GB — and runs locally on the Mac's GPU, with a CPU fallback. Your voice sample stays on the Mac.
05
A Short Sample of Your Own Voice
The engine needs a 6–15 second clip of your speech. Take it from the video itself, or record a sample by reading a short script aloud for about 15 seconds. You confirm that it is your own voice before it is used.
06
Offline Translator or an AI Agent
Translate with the built-in offline translator (m2m100, about 2 GB), which runs on the Mac and is more literal, or with an AI agent such as Claude Code or Codex for a freer translation.
Why Dub in Your Own Voice
Subtitles help, but many viewers will not read them, especially on phones and in short videos. A dub with a stock voice works, but it no longer sounds like you, which matters for tutorials, courses and product videos where your voice is part of the brand. Voice dubbing keeps the same video, the same edit and the same voice, and changes only the language. For creators who publish in English and also have an audience in Spanish, Portuguese, Hindi or Turkish, that makes a second version a matter of one run instead of a second recording session.
What Happens When You Press Translate
The run goes through four steps: captions, translating, speaking in your voice, and adding to the timeline. The app reuses the video's captions as the source text — or transcribes the speech first if there are none — translates them with the translator you picked, generates each line in your voice with Chatterbox Multilingual, and places the takes on the timeline with the captions switched to the target language. Takes that run longer than the original line are sped up to fit. When it finishes, ⌘Z undoes the whole change if you want to try another language or translator.
Own Voice Only, and a Watermark
Voice cloning can be misused, so the Voice tab is limited to your own voice: you confirm "This is my own voice" before a sample is created, and the sample is kept on your Mac. The audio the engine produces carries Resemble AI's Perth watermark, which is inaudible to listeners. The voice engine needs a Mac with Apple silicon; on other Macs the captions can still be translated. If you need the disk space back, the voice engine can be removed while your voice sample is kept.

Frequently Asked Questions
What to know before dubbing a video in your own voice.
Which languages can I dub into?
23 languages: Arabic, Chinese, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese, Russian, Spanish, Swahili, Swedish and Turkish.
Does dubbing upload my voice or video to a server?
The voice engine runs on your Mac, and your voice sample stays on the Mac. If you choose the built-in offline translator, translation also runs locally. If you choose an AI agent for translation, the text is handled by that agent.
How long does my voice sample need to be?
The engine uses a 6–15 second clip of your speech. You can take it from the video, or record a sample by reading the short script shown in the app for about 15 seconds.
Can I dub someone else's voice?
No. The Voice tab is for your own voice only, and you confirm that before a sample is created.
How big is the download?
The voice engine is installed on demand and takes about 4 GB. The built-in offline translator is about 2 GB. You can remove the voice engine later to free the space.
Which Macs does voice dubbing work on?
The voice engine needs a Mac with Apple silicon. On other Macs, captions can still be translated.
Are the captions translated as well?
Yes. The captions switch to the target language in the same run and are timed to your dubbed voice.
Is the dubbed audio marked as AI-generated?
Yes. The engine's output carries Resemble AI's Perth watermark, which is inaudible.
