English-language creators, schools and companies translate their videos because four in five people on earth don't speak English, and most of them would rather watch in their own language.
Spanish has the second-largest number of native speakers in the world, about 487 million after Mandarin, and 561 million speakers in all. It is official in 20 countries; Mexico alone has more than twice Spain's population, and the United States is home to one of the largest Spanish-speaking communities anywhere.
Latin American and European Spanish share their grammar but differ in accent and some everyday words (computadora or ordenador, carro or coche), and Spain uses vosotros for 'you all'. If most of your viewers live in one region, watch the dub once with them in mind.
Spanish has an informal tú and a formal usted. Creators usually talk to viewers with tú; banks, healthcare and B2B companies tend to use usted. Watch the first dub to make sure the tone matches your brand.
Spanish text typically runs 15–25% longer than English, and Spanish is spoken at about 7.8 syllables a second (Pellegrino et al., 2011). AutoDub lets each line take the time it needs instead of rushing the voice.
English is compact: the same idea usually takes more words in Spanish, French or German, and localization teams plan for 15–35% longer text. AutoDub lets the timing stretch slightly instead of speeding the voice up, so the translated speech keeps a natural pace.
