You can design an Australian AI voice with one prompt
Describe the accent, gender, age and delivery in one sentence and Gradium returns a Australian voice id you call from the API or the SDK. The library already carries 6 Australian voices, and Voice Design covers whatever it does not.
Aussie accent, Australia accent, Ocker accent and australian all describe the same voice. Write it as Australian English in your prompt.

The prompt
that produced it
An Australian female voice, 40 to 50: mid-low pitch, steady natural pacing, medium energy and warm rounded resonance. Accent detail: non-rhotic with broad open vowels, raised KIT and DRESS, terminal rise. Ideal for reassuring walkthroughs and empathic de-escalation.
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
- slowfast
- Energy2/5
- calmboisterous
Australian
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 Non-rhotic with a broad drawl: it is the feature a mid-range read is most likely to soften, and the one a listener places Australian by.
An Australian 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 Australian it usually costs non-rhotic with a broad drawl.
An Australian 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 High rising terminal, which a support brief tends to flatten.
An Australian 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 Australian is no exception: push it and listen for whether non-rhotic with a broad drawl survives.
An Australian 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 Australian
sound like itself
Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.
- Non-rhotic with a broad drawl
- Post-vocalic /r/ is dropped as in British, but the vowel that replaces it is longer and more open. Car sits closer to cah with a broader tail, which is what listeners register as Australian before any other feature.
- High rising terminal
- Declarative statements often end on a rise rather than a fall. It reads as friendly and unfinished rather than uncertain, and it is the reason Australian suits conversational and hospitality work with very little prompt effort.
- KIT and DRESS raising
- The vowels in kit, dress and trap sit higher and further forward than in British or American, so fish leans towards feesh and bed towards bid. Scripts loaded with these vowels audition the accent fastest.
- Weak-vowel merger
- Unstressed vowels collapse towards schwa, so rabbit and abbot rhyme in a way they do not in Standard British. Requesting very crisp articulation fights this and can pull the read towards a neutral English that is no longer recognisably Australian.

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 | Australian 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 very crisp articulation fights the weak-vowel merger and pulls the accent towards a neutral English that is no longer Australian.
- Leave articulation alone. Broadness comes from the vowels, and precision is the fastest way to undo it.
- Requesting formality or authority conflicts with the terminal rise, giving a read that sounds uncertain rather than authoritative.
- Choose Standard British or General American for authoritative work. Australian is built for warmth and approachability.
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 Australian 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 Australian 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.
Non-rhotic with a broad drawl above all: Post-vocalic /r/ is dropped as in British, but the vowel that replaces it is longer and more open. Car sits closer to cah with a broader tail, which is what listeners register as Australian before any other feature.
6 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. Australian 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.

in the studio
Every voice we ship clears blind listener comparison and an ELO ranking first, because roughly one candidate in a thousand has it. For Australian, the feature that decides it is usually Non-rhotic with a broad drawl.
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.
