Describe the accent, gender, age and delivery in one sentence and Gradium returns a Swiss German voice id you call from the API or the SDK. Every Swiss German voice is built to order, so the age, gender and delivery are yours to specify rather than picked from a shelf.
Schwyzerdütsch, Swiss accent, Zurich accent, Schweizerdeutsch and swiss german all describe the same voice. Write it as Swiss German in your prompt.
Hear it
“Schau dir das an, der Kaffee ist heute wieder einmal eine Frechheit.”
A Swiss German male voice, 45 to 55: low pitch, slow pacing, low energy and measured institutional resonance. Accent detail: frequent velar fricatives, slow even tempo, full syllable weight. Ideal for corporate announcements and compliance.
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.
Age is the part of a voice a fixed library cannot vary. Written into the prompt, it comes back in the voice.
Eine Männerstimme in Schweizer Hochdeutsch, 50 Jahre, ruhig und deutlich artikuliert, gemächliches Tempo, Zürcher Färbung.
The prompt that produced the clip above.
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 Lexically distant from Hochdeutsch: it is the feature a mid-range read is most likely to soften, and the one a listener places Swiss German by.
A Swiss 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.
Pitch, pace and energy drop together. Moving one alone produces a voice performing gravity rather than carrying it, and in Swiss German it usually costs lexically distant from hochdeutsch.
A Swiss German 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 Velar fricatives throughout, which a support brief tends to flatten.
A Swiss German 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 Swiss German is no exception: push it and listen for whether lexically distant from hochdeutsch survives.
A Swiss German 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.
Each feature below is something the prompt has to encode, or something a careless prompt will accidentally undo.
What Swiss German tells a listener
Voice Design generates Swiss German 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 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 | Swiss German |
| 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.
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 German terms rather than translating one that worked elsewhere.
Writing your first prompt? How to write a voice prompt covers every part a prompt can carry, and what each one changes.
A Swiss German 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 Swiss German, 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.
Lexically distant from Hochdeutsch above all: Swiss German differs enough in vocabulary and grammar to be hard for German speakers to follow, unlike every other variety here. Confirm whether the brief wants Swiss German or Swiss-accented standard German, because they are not the same product.
Describe it and Voice Design builds it. Voice Design generates Swiss German 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.
Distance. German listeners often cannot follow it, and Swiss German speakers appear subtitled on German television, so the accent signals foreignness within the language in a way no other variety does.
Include Chuchichäschtli, Grüezi, Rösti. Those expose the accent, where a neutral paragraph any accent could read tells you nothing about whether it landed.
Those are names for the same territory, and this page covers them. Swiss German 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 Swiss German, the feature that decides it is usually Lexically distant from Hochdeutsch.
Paste the prompt, change the parts that matter to you, and generate. No recording, no casting, no licensing.
