Why Portuguese

Why translate Spanish videos into Portuguese?

Spanish-speaking creators, from Mexico City to Madrid, translate into English to reach the US mainstream, international brands and viewers who never search in Spanish.

Portuguese has about 269 million speakers, and roughly four in five of them live in Brazil, one of the largest and most engaged online video audiences in the world. Portugal, Angola and Mozambique add tens of millions more, and the language is official in nine countries.

Language notes

What changes from Spanish to Portuguese

Brazil or Portugal

Brazilian and European Portuguese differ in pronunciation, some vocabulary (ônibus or autocarro for 'bus') and how people say 'you' (você or tu). Brazil is by far the larger audience; if most of your viewers are in Portugal, watch the dub once with them in mind.

A dubbing audience

Dubbing (dublagem) is the norm for TV and streaming in Brazil, and Brazilian viewers are used to hearing foreign content in Portuguese, so a dubbed video feels at home.

Longer lines

Portuguese usually needs more words than English for the same idea. AutoDub lets each line take a little more time instead of speeding the voice up, so the dub keeps a natural pace.

Coming from Spanish

Spanish is fast, about 7.8 syllables a second against English's 6.2, but carries less meaning per syllable (Pellegrino et al., 2011), so an English version of a Spanish speaker usually fits comfortably in the original timing.

Spanish and Portuguese

Spanish and Portuguese share most of their grammar and much of their vocabulary, and readers often follow each other's writing. Speech is another matter: Brazilian Portuguese sounds very different, and false friends abound (exquisito is 'exquisite' in Spanish, esquisito is 'strange' in Portuguese). A dub lets Brazilian viewers hear you without effort.
