You can design an Austrian German AI voice with one prompt

Describe the accent, gender, age and delivery in one sentence and Gradium returns a Austrian German voice id you call from the API or the SDK. The library already carries 4 Austrian German voices, and Voice Design covers whatever it does not.

Österreichisch, Viennese accent, Wienerisch, Vienna accent and austrian german all describe the same voice. Write it as Austrian German in your prompt.

Hear it

The prompt
that produced it

An Austrian German female 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.

The same accent at 34
from one prompt

Age is the part of a voice a fixed library cannot vary. Written into the prompt, it comes back in the voice.

Eine höfliche österreichische Frauenstimme, 34 Jahre, freundlich und zugewandt, weicher Wiener Klang, mittleres Tempo.

Austrian German
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.

Pitch 3 · Pace 3 · Energy 3

Everything to the middle. Watch Lenition of P, T and K: it is the feature a mid-range read is most likely to soften, and the one a listener places Austrian German by.

An Austrian German 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.

What makes Austrian German
sound like itself

Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.

Lenition of P, T and K
The voiceless stops soften, so Austrian German blurs the contrast between p and b or t and d in a way Hochdeutsch keeps sharp. It is the main reason the variety reads as gentler even at the same pitch and pace.
Different vowel quality
Several vowels are more open and slightly longer than their German equivalents, which lengthens the whole line without changing the pace value. A prompt asking for slow pacing on top of this can produce a read that drags.
Softer final consonants
Final devoicing still applies but lands less hard than in Hochdeutsch, so word endings are less clipped. Combined with lenition this is what listeners describe as the Austrian warmth.
Austrian, not Bavarian
The two share features and are often confused, but they are separate mapped labels. Austrian German is the standard variety of Austria; Bavarian is a German regional dialect. Naming the wrong one gets the wrong voice.

What Austrian German tells a listener

What it signals
Charm and unhurried sociability. Kaffeehaus culture is part of what the accent signals, and Austrian German reads as softer and more courteous than any German variety while remaining a national standard rather than a dialect.
Where it is spoken
Austria, with the Viennese variety the most widely recognised.
Where it is heard
ORF and Austrian film. German listeners hear it as a separate country rather than a region, which is a different relationship from the one they have with Bavarian.
Audition words
Put Kaffeehaus, Apfelstrudel, Servus in the line you generate. A neutral paragraph any accent could read tells you nothing about whether the accent landed.

Every voice we ship clears blind listener comparison and an ELO ranking first, because roughly one candidate in a thousand has it. For Austrian German, the feature that decides it is usually Lenition of P, T and K.

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.
