You can design an Indian English AI voice with one prompt
Describe the accent, gender, age and delivery in one sentence and Gradium returns a Indian English voice id you call from the API or the SDK. The library already carries 3 Indian English voices, and Voice Design covers whatever it does not.
Desi accent, Hinglish, Indian accent, Hindi-accented English and indian english all describe the same voice. Write it as Indian English in your prompt.

The prompt
that produced it
An Indian English male voice, 55 to 65: clean, deliberate and precise, with low pitch, slow pacing, low-to-mid energy, resonant timbre and a gentle low-to-high flow. Ideal for projecting academic authority.
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.
- Pitch1/5
- lowhigh
- Pace2/5

- Energy2/5

Indian English
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 Retroflex stops: it is the feature a mid-range read is most likely to soften, and the one a listener places Indian English by.
An Indian English male 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 Indian English it usually costs retroflex stops.
An Indian English male 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 Syllable-timed rhythm, which a support brief tends to flatten.
An Indian English male 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 Indian English is no exception: push it and listen for whether retroflex stops survives.
An Indian English male 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 Indian English
sound like itself
Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.
- Retroflex stops
- The /t/ and /d/ are produced with the tongue curled back against the hard palate rather than at the alveolar ridge. It is the single most identifiable feature, and it survives even at fast pacing, so it does not need reinforcing in the prompt.
- Syllable-timed rhythm
- Syllables receive more even weight than in stress-timed American or British English, which flattens the contrast between stressed and unstressed. This makes the accent unusually legible at speed, and it is why it performs well for instructional and support content.
- Monophthongal FACE and GOAT
- The vowels in face and goat are held as single steady vowels rather than glided diphthongs, so face leans towards fes and goat towards got. Asking for a smooth or gliding delivery works against this and blurs the accent.
- Reduced aspiration and clear /v/
- Initial /p/, /t/ and /k/ carry less aspiration, and /v/ and /w/ sit closer together than in other varieties. The result reads as precise rather than clipped, which pairs well with a formal or educational purpose.

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 | Indian English |
| Gender | male |
| Age range | 55 to 65 |
| Character | clean, deliberate and precise |
| Pitch | low pitch |
| Pace | slow pacing |
| Energy | low-to-mid energy |
| Resonance / timbre | resonant timbre |
| Modifiers | a gentle low-to-high flow |
| Applications | projecting academic authority |
2 failure modes we hit repeatedly, and what fixes each one.
- Asking for a smooth or gliding delivery works against the monophthongal FACE and GOAT vowels and blurs the accent.
- Ask for clarity instead. The accent is already unusually legible, and clarity reinforces what is there.
- Requesting a heavy stress pattern for emphasis fights the syllable-timed rhythm and makes the read sound uneven.
- Get emphasis from energy and pitch rather than from stress. The even rhythm is a feature for instructional work.
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 English terms rather than translating one that worked elsewhere.

An Indian English male voice, 55 to 65: clean, deliberate and precise, with low pitch, slow pacing, low-to-mid energy, resonant timbre and a gentle low-to-high flow. Ideal for projecting academic authority. Name the accent as Indian English, 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.
Retroflex stops above all: The /t/ and /d/ are produced with the tongue curled back against the hard palate rather than at the alveolar ridge. It is the single most identifiable feature, and it survives even at fast pacing, so it does not need reinforcing in the prompt.
3 are ready to call today, with no design step: pick a voice id and go. Design one when you want an age, texture or persona of your own.
Those are names for the same territory, and this page covers them. Indian English 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 Indian English, the feature that decides it is usually Retroflex stops.
Open a voice, type your own script, and listen. Then write a prompt of your own to design a variant. No recording, no casting, no licensing.
