# Dub a Video to Spanish

ToolSugar dubs a video into Spanish. It transcribes your video, translates the lines to Spanish and reads them with Dora or Alex, all in your browser with nothing uploaded. Spanish often needs more syllables than English, so longer lines play faster to stay in place. You get an MP4 and a Spanish SRT file.

Runs on your device

## How it works

1. Drop your video and, if detection gets it wrong, pick the spoken language.
2. Pick Dora or Alex. Both are voiced on your device.
3. Press Dub video, then open the note under the result to see whether any line was cut to fit.

## Key facts

- **Spanish voices**: Dora and Alex, both in your browser
- **Translation style**: Neutral Spanish from a small translation model. It is not tuned for one country
- **Common limit**: Fast English speakers leave little room, so more lines reach the 1.6x speed limit
- **Long lines**: Long lines are split into shorter pieces before the voice reads them

## Common uses

- Offering a Spanish version of a software walkthrough to customers in Latin America.
- Dubbing a church talk or community notice for Spanish-speaking members.
- Adapting a marketing explainer for a campaign in Spain or Mexico.

## Questions

### Can I choose Latin American or European Spanish?

Not at the moment. The translation model targets Spanish in general and writes in a neutral style, and the voices are not labelled by country. If you need a specific regional wording, edit the SRT file and treat this dub as a first draft.

### Which voice sounds best in Spanish?

Try a short clip with each one, since taste differs. Both run on your device and share the same 86 MB download, so switching between them costs nothing extra. Each dub counts as one of your 5 free AI runs in any rolling 24 hours.

### Why did some of my lines get cut off?

Spanish can run a quarter longer than the same sentence in English. A line that still overflows at 1.6 times speed is faded out when the next line begins. Slower source speech, with pauses between sentences, leaves more room and avoids this.
