About OpenDub

Screenshot of the OpenDub homepage
The OpenDub homepage

OpenDub is an open source AI dubbing tool that automatically translates videos into 17 languages while preserving the original speaker's voice and tone. It works in your browser without requiring installation, API keys, or account creation for basic use, processing videos locally with only speech clips sent to voice models.

The software offers multiple voice cloning options: a free stock voice in the browser, OmniVoice for free local voice cloning on your computer, or commercial models like Higgs Audio and ElevenLabs using your own API key. Each dubbed line is timed to match the original speech duration and can carry the speaker's tone including surprise, enthusiasm, or calm.

OpenDub separates speech from background music and effects, transcribes the audio, translates sentences to fit their timing, and regenerates speech in the target language. Users can edit translations, adjust timing and tone per line, and receive output files including the dubbed MP4, audio as WAV, and subtitles in both languages.

FAQ

What is AI dubbing?
AI dubbing replaces the speech in a video with speech in another language using AI models. OpenDub's AI dubbing transcribes the original, translates each sentence to fit its moment and speaks it in a clone of the original voice, keeping the music underneath.
Is my video uploaded?
No. During AI dubbing the video stays on your device. Only speech clips and text go to the voice model you choose.
Which languages can it dub into?
AI dubbing supports 17 languages: English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Português, Italiano, Русский, हिन्दी, Bahasa Indonesia, Bahasa Melayu, Tiếng Việt, ไทย, العربية. The language of the original video is detected automatically.
Do I need an account?
No. OpenDub needs no account.
Does it keep the background music?
Yes. Replace the voice keeps the music and effects and swaps only the speech. Voice-over leaves the original faintly underneath.
