Translate Video to Spanish: Dubbed or Subtitled
Upload a video in English or another language and BlaBlaScribe translates it into Spanish: as subtitles you can export, or as a dub with a Spanish voice for each speaker and the music kept. Spanish text runs about 19% longer than English, so every dubbed line is fitted to its slot before it is voiced.

Videos People Translate Into Spanish
A lesson recorded in English reaches learners in Mexico, Spain and Argentina. Spanish subtitles cost nothing extra on paid plans; a dub is worth it where people watch the screen, not the text.
Add a Spanish audio track to the same video, or Spanish subtitles if your viewers prefer the original voice. Either way, views and comments stay on one video.
Keep the music and sound design, change only the voice, and fix your product names once in the transcript so they are said the same way in every line.
How Much Longer Is Spanish Than English?
We measured 2,009 sentences professionally translated from English in the FLORES-200 benchmark. Spanish is among the longest of the languages we dub into.
| Language | Text vs English | Sentences 15%+ longer | Time to say it vs English |
|---|---|---|---|
| Spanish | +19% | 59% | +10% |
| French | +19% | 61% | +9% |
| Italian | +18% | 56% | +13% |
| German | +17% | 53% | +20% |
| Dutch | +12% | 40% | — |
| Russian | +9% | 33% | — |

| Turkish | +3% | 19% | — |
| Swedish | +1% | 9% | — |
Text length is counted in characters. Spanish speakers say more syllables per second than English speakers (7.8 against 6.2), so a Spanish line takes about 10% longer to say rather than 19%. Time to say it comes from recordings by native speakers in Pellegrino, Coupé and Marsico (2011); a dash means the language was not in that study.

What You Get in Spanish

Before You Publish the Spanish Version
Spanish is long and regional; these checks catch most of what a native viewer would notice.
Region
Choose words for your audience
There is one Spanish option, not separate ones for Spain and Latin America. Read the translation and change words that differ by region, such as ordenador and computadora, before you dub.
You
Decide between tú and usted
Tutorials and YouTube usually speak to the viewer as tú; corporate training and customer videos often use usted. Keep one form through the whole video.
Length
Shorten the dense lines
With six in ten sentences coming out 15% longer, fast talkers produce flagged lines. Shorten the flagged ones rather than accepting a voice that rushes.
Names
Fix names in the transcript first
Correct product names, people and places in the original transcript, so the Spanish text and voice repeat them correctly everywhere.
