You can design a Caribbean Spanish AI voice with one prompt
Describe the accent, gender, age and delivery in one sentence and Gradium returns a Caribbean Spanish voice id you call from the API or the SDK. Every Caribbean Spanish voice is built to order, so the age, gender and delivery are yours to specify rather than picked from a shelf.
Cuban Spanish, Puerto Rican Spanish, Boricua accent, Dominican Spanish and caribbean spanish all describe the same voice. Write it as Caribbean Spanish in your prompt.

The prompt
that produced it
A Caribbean Spanish male voice, 35 to 45: mid pitch, steady natural pacing, medium energy and an easy unforced resonance. Accent detail: heavy s-aspiration, fast front-loaded tempo, wide melodic range. Ideal for natural dialogue and voice agents.
A worked example: change any part of it and the voice changes with it. The four styles below show what moving pitch, pace, energy or purpose does to the same accent.

Caribbean Spanish
in four styles
A prompt is built from parts: the accent, the age, then pitch, pace, energy and what the voice is for. Change one part and you get a variation. These four are starting points to adapt, not finished prompts.
Everything to the middle. Watch Heavy S aspiration and loss: it is the feature a mid-range read is most likely to soften, and the one a listener places Caribbean Spanish by.
A Caribbean Spanish female voice, 30 to 45: easy and unforced, with mid pitch, steady natural pacing, medium energy and a natural unforced resonance. Ideal for voice agents, assistants and dialogue that has to sound unscripted.
In colour: the 9 parts that make this style.
Pitch, pace and energy drop together. Moving one alone produces a voice performing gravity rather than carrying it, and in Caribbean Spanish it usually costs heavy s aspiration and loss.
A Caribbean Spanish female voice, 45 to 60: clean, deliberate and precise, with low pitch, slow pacing, low energy and deep resonant timbre. Ideal for audiobooks, documentary and long-form narration.
In colour: the 9 parts that make this style.
Warmth belongs in the resonance rather than the energy. Keep an ear on R and L interchange, which a support brief tends to flatten.
A Caribbean Spanish female voice, 35 to 50, for customer service: calm and crisp, with mid-low pitch, steady natural pacing, medium energy and warm rounded resonance. Ideal for reassuring walkthroughs and empathic de-escalation.
In colour: the 10 parts that make this style.
Check this by ear before committing. How much energy an accent carries before it reads as theatrical varies sharply, and Caribbean Spanish is no exception: push it and listen for whether heavy s aspiration and loss survives.
A Caribbean Spanish female voice, 25 to 35: bright and punchy, with mid-high pitch, fast pacing, high energy and bright forward resonance. Ideal for advertising reads and social video.
In colour: the 9 parts that make this style.
What makes Caribbean Spanish
sound like itself
Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.
- Heavy S aspiration and loss
- Final s weakens or disappears more thoroughly than anywhere else in Spanish, so estas casas leans towards eta casa. It is the region's structural signature.
- R and L interchange
- In parts of the Caribbean final r and l swap, so puerta leans towards puelta. It is strongly marked and belongs in character work rather than corporate reads.
- Fast, front-loaded tempo
- Caribbean Spanish carries the quickest default rhythm of the Spanish varieties. A fast pace value reads as natural where it would sound rushed in Andean Spanish.
- Wide melodic range
- Pitch moves considerably more than in Mexican or Castilian Spanish, which is the warmth people choose the accent for. A flat read removes it.
Design your own custom Caribbean Spanish voice
for your use case
Voice Design generates Caribbean Spanish voices to order, so you specify the age, gender and delivery you need rather than choosing from a shelf. This is the difference between a voice library and a voice model: a library can only offer you what it already holds, while Voice Design builds the accent on request.
The prompt,
and where it goes wrong
The method behind the prompt: what each clause does, what breaks it, and what it was tested on.
Each row is one part of the prompt above and what it is set to here. Change a single row and you get a variation on this voice; change several and you get a different one.
| Clause | This prompt |
|---|---|
| Accent / localechanged | Caribbean Spanish |
| Gender | female |
| Age range | 20 to 30 |
| Character | glossy and confident |
| Pitch | high pitch |
| Pace | fast pacing |
| Energy | high energy |
| Resonance / timbre | bright sparkling resonance |
| Modifiers | girly chatter |
| Applications | a friendly receptionist or assistant |
2 failure modes we hit repeatedly, and what fixes each one.
- Asking for crisp or fully articulated delivery removes the s-aspiration, which is the accent's structural signature.
- If the brief needs full articulation, use Mexican or Andean Spanish instead.
- The r and l interchange is strongly marked and reads as caricature in corporate work.
- Keep it for character work, and use a neutral Latin American accent for brand voices.
Descriptor words do not transfer between languages. Energetic and bright travel intact, but most resolve to a different sound depending on the language they are read in, so a brief that produced a warm voice in one language will not produce the equivalent warmth translated into another. Write it in Spanish terms rather than translating one that worked elsewhere.

A Caribbean Spanish female voice, 20 to 30: glossy and confident, with high pitch, fast pacing, high energy, bright sparkling resonance and girly chatter. Ideal for a friendly receptionist or assistant. Name the accent as Caribbean Spanish, then set the age, the pitch, the pace, the energy and what the voice is for. Every accent Gradium maps is reached the same way.
Heavy S aspiration and loss above all: Final s weakens or disappears more thoroughly than anywhere else in Spanish, so estas casas leans towards eta casa. It is the region's structural signature.
Describe it and Voice Design builds it. Voice Design generates Caribbean Spanish voices to order, so you specify the age, gender and delivery you need rather than choosing from a shelf. One prompt returns a voice id you can call from the API straight away.
Those are names for the same territory, and this page covers them. Caribbean Spanish is the wording Gradium maps, so that is what to name in the prompt, but a brief written in any of these terms lands in the same place.
Both. Gender is its own part of the prompt, so it changes on its own: swap male for female and everything else holds. Same accent, same age, same delivery, different voice.
Yes. A designed voice is generated rather than cloned from a person, so there is no actor to license and no session to re-book when the script changes.
