Castilian Spanish — Production Guide
Choosing the wrong Spanish variant costs productions time and credibility. Here is what actually separates Castilian from Latin American Spanish — written by a native Castilian voice actress who records both markets from a Madrid studio.
The Basics
Castilian Spanish — often called "Spain Spanish" or "European Spanish" — is the standard Spanish spoken in Spain. It is 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 reference standard.
Not all Spanish voice talent delivers authentic Castilian. The difference lives in the "z" sound, pronounced as a soft "th" before "e" and "i"; in the "s", kept sharp rather than aspirated; and in the 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 is not learned. It is lived.

Why Castilian Spanish Matters
Not all Spanish is the same. For international campaigns targeting European audiences — or productions that need authenticity in the Spanish-speaking world — Castilian Spanish carries a different weight. Here's the difference:
| Aspect | Castilian Spanish | Latin American Spanish |
|---|---|---|
| Origin | Spain (Peninsular) | Latin America |
| Use of "Vosotros" | ✓ Used in everyday speech | ✗ Not used |
| Lisped "C" and "Z" | ✓ Authentic /θ/ sound | varies by region |
| Dubbing Standard | Preferred for European dubbing | Preferred for LATAM dubbing |
| International Campaigns | Standard for Spain + European markets | Standard for Americas |
| Brand Perception | Prestige, authority, authenticity | Varies by target market |
