# Video Language Changer

To change the language a video is spoken in, ToolSugar reads the speech, translates it and replaces the audio with an AI voice timed to the original lines, all in your browser. Eight languages have a voice. Japanese, Chinese, Korean and Arabic do not yet, so only subtitles are possible there.

Runs on your device

## How it works

1. Drop your video, then open the language list and choose the language you want to hear.
2. Check the voice note. A language with no voice is flagged before you start.
3. Press Dub video to replace the sound, or use Video Translator if subtitles are enough.

## Key facts

- **Voices**: English, British English, Spanish, French, German, Hindi, Italian and Brazilian Portuguese
- **Free runs**: Each dub counts as one of 5 free AI runs in any rolling 24 hours, with no sign up
- **No voice yet**: Japanese, Chinese, Korean and Arabic. The tool tells you so before you start
- **German voice**: A Piper voice of about 20 MB, smaller than the others but lower in quality

## Common uses

- Comparing how the same video sounds in two languages before choosing a market.
- Replacing the language of a short promo when subtitles would cover the picture.
- Making an audio-first version of a lesson for people who cannot read subtitles easily.

## Questions

### Should I use subtitles or a dub?

Subtitles keep the original voice and music, and they are much quicker to make. A dub suits viewers who listen rather than read, such as children or people watching while they work. If you are unsure, start with subtitles and test the dub on one clip.

### Can the video keep both languages?

No. The MP4 has one audio track, with the new language only. Keep your original file for the first language. Publishing platforms that accept extra audio tracks can take the dubbed version's sound as a separate upload.

### Why can I not dub into Japanese, Chinese or Korean?

No free voice we could clear for commercial use runs in the browser for those languages, or for Arabic, so the tool cannot make audio there. Translation can still write them, so Video Translator gives you subtitles. A voice may come later.
