Castilian Spanish
Castilian (Castellano, es-ES) is Spanish as spoken in Spain. Key differences from Latin American Spanish:
| Feature | Castilian (Spain) | Latin American |
|---|---|---|
| Sound "z", "ce", "ci" | [θ] — "Barthelona" | [s] — "Barselona" |
| "You" (plural, informal) | vosotros queréis | ustedes quieren |
| Intonation | More melodic | More flat |
| Voices available | 104 voices | 41 voices |
When to choose Castilian: your audience is in Spain, content for European region, tourism in Spain, learning "classic" Spanish.
When to choose another accent: for USA and Mexico → Mexican, for all Latin America → Colombian or Mexican.

Frequently Asked Questions
What is the difference between Castilian and Latin American Spanish?
Castilian Spanish (es-ES) uses the "theta" sound [θ] for letters "z" and "c" before "e" or "i" — like "th" in "think". Latin American Spanish uses regular [s] sound. Castilian also uses "vosotros" form for informal plural "you", while Latin America uses "ustedes".
Why does my Spanish text sound unnatural?
Most likely missing accent marks (á, é, í, ó, ú) or inverted punctuation (¿, ¡). Spanish TTS relies on these to determine correct pronunciation and intonation. Always include them in your text.
How do I make English brand names sound correct?
Write them phonetically in Spanish: Google → Gúgol, WhatsApp → Guasap, YouTube → Yutub. TTS reads by Spanish rules, so English spelling produces strange pronunciation.
Should I use Castilian or Mexican Spanish?
Use Castilian (es-ES) if your audience is in Spain or Europe. Use Mexican (es-MX) for USA, Mexico, or international content — it's considered more neutral. Spanish listeners can immediately tell the difference.
