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

The prompt
that produced it
A Chilean Spanish female voice, 30 to 40: mid pitch, steady natural pacing, medium energy and an easy unforced resonance. Accent detail: ch towards sh, heavy final consonant loss, quick compressed delivery. 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.

Chilean 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 final consonant loss: it is the feature a mid-range read is most likely to soften, and the one a listener places Chilean Spanish by.
A Chilean 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 Chilean Spanish it usually costs heavy final consonant loss.
A Chilean 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 CH becomes SH, which a support brief tends to flatten.
A Chilean 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.

Check this by ear before committing. How much energy an accent carries before it reads as theatrical varies sharply, and Chilean Spanish is no exception: push it and listen for whether heavy final consonant loss survives.
A Chilean 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 Chilean Spanish
sound like itself
Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.
- Heavy final consonant loss
- Final s and d weaken or drop extensively, and the accent compresses more than any other Spanish variety. It is the reason Chilean is considered the hardest for other Spanish speakers to follow.
- CH becomes SH
- The ch softens towards sh, so Chile leans towards Shile. It is the marker Chilean listeners recognise first.
- Very fast default tempo
- Chilean Spanish runs quicker than any other mapped variety. Requesting fast pacing on top pushes past intelligibility, so keep pace neutral.
- Built to your spec
- Describe the Chilean voice your product needs and Voice Design generates it, tuned to the age, gender and delivery you ask for.
Design your own custom Chilean Spanish voice
for your use case
Voice Design generates Chilean 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 | Chilean 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.
- Requesting fast pacing pushes past intelligibility, because Chilean already compresses more than any other mapped Spanish variety.
- Keep pace neutral or below. This is the one Spanish accent where speed is the risk.
- Asking for fully articulated endings removes the final consonant loss and produces a generic Latin American read.
- If clarity is the priority, choose Mexican or Andean Spanish instead.
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 Chilean 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 Chilean 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 final consonant loss above all: Final s and d weaken or drop extensively, and the accent compresses more than any other Spanish variety. It is the reason Chilean is considered the hardest for other Spanish speakers to follow.
Describe it and Voice Design builds it. Voice Design generates Chilean 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. Chilean 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.

Every voice we ship clears blind listener comparison and an ELO ranking first, because roughly one candidate in a thousand has it. For Chilean Spanish, the feature that decides it is usually Heavy final consonant loss.
