Native Castilian Spanish voice over artist. 15+ years working with international brands, studios, and production companies. She doesn't translate — she performs.
Castilian Spanish — often called "Spain Spanish" or "European Spanish" — is the standard Spanish spoken in Spain. It's distinct from Latin American Spanish in pronunciation, intonation, and certain vocabulary choices. For international productions targeting Spanish-speaking audiences in Europe, or global brands that need an authoritative Spanish voice, Castilian is the gold standard.
Not all Spanish voice talent delivers authentic Castilian. The difference is in the "z" sound (pronounced like a soft "th" before "e" and "i"), the "s" pronunciation (kept sharp rather than aspirated), and the specific idiomatic expressions that only come from growing up immersed in the language.
Joanna Rubio was born in England and raised in Madrid — fully bilingual from childhood, with Castilian Spanish as her native tongue and International English at the same level. This isn't learned — it's lived.
