Your brand has a voice. Most AI translations ignore it.
Generic machine translation doesn't know whether your brand is warm and direct or formal and authoritative. The Brand Voice Manager lets you define how your brand speaks — once — and Flixu enforces those rules on every translation request, automatically.
The Brand Voice Manager is a configuration layer in Flixu that stores your tone definition — formality level, sentence structure, stylistic preferences, and phrasing constraints. Every translation request receives that configuration before the language model processes the text. Your German marketing copy sounds like your brand sounds in German, not like the statistical average of German business writing.
How the Brand Voice Manager works.
Brand voice in a translation pipeline is a sequencing problem. Most tools apply style guidance after translation — a style guide document that a human reviewer checks against, or a post-generation prompt that tries to adjust tone. By the time the review happens, the output already has the wrong register and needs to be rewritten. Flixu applies your brand voice configuration before the language model generates anything.
Define your voice
You write your brand voice instructions in natural language — the same way you'd brief a human translator. Formality level, tone, sentence structure, specific constructions to avoid.
Tone: Warm, direct, slightly informal.
Formality: Casual (du in German, tu in French — never Sie or vous).
Sentences: Short to medium. Active voice. No passive constructions.
Avoid: Corporate filler phrases, excessive hedging, exclamation points.
These instructions are stored in your workspace as a named Brand Voice profile. You can create multiple profiles — one for your product UI, one for marketing copy, one for legal documentation — each with different parameters.
Assign to projects or clients
Each Brand Voice profile is assigned to a project or client workspace. When a team member opens a project for that client, the profile is already active. There's no configuration step per translation — the voice travels with the project, not with the individual request.
Applied automatically before translation
When a translation request runs, the brand voice instructions are injected into the payload before the language model receives the text. The model doesn't see the source content and a suggestion to apply a certain style — it sees source content with the style already specified as a constraint. The output is generated to those specifications from the first word.

What the Brand Voice Manager controls.
Tone and Instructional Style
Write your tone guidelines the way you'd write a brief for a human translator: "Use short, punchy sentences. Active voice throughout. Conversational — like you're talking to a colleague, not writing a press release." The language model applies those instructions to every string it generates for that project.
Formality Control
Lock the formal or informal register before translation begins. German Sie/du, French vous/tu, Japanese keigo levels, Spanish usted/tú — the formality dimension is specified as a constraint, not inferred from the source text. The model can't produce mixed register output because the instruction was part of the input.
Multi-Profile Support
One account, multiple voices. Assign a "Marketing" profile that's warm and casual to your campaign content. Assign a "Legal" profile that's precise and formal to compliance documentation. Assign a client-specific profile to each agency client workspace. The profiles are independent and don't affect each other.
Voice Testing
Before applying a profile to a large document, test it against a sample string using the Quick Translate widget. See the same source sentence rendered with two different brand voice configurations side by side. Adjust the instructions and re-test until the output matches what you're aiming for.

Marketing teams running multilingual campaigns
A marketing team spends months developing a brand voice in English — direct, warm, slightly irreverent. Their agency translates it into German and it comes back formal and stiff. The content team rewrites it. That correction cycle repeats for every campaign, every language, every quarter.
With Brand Voice Manager, the formality and tone are configured once. The German campaign arrives with the correct register applied. The team reviews for cultural nuance, not for basic tone correction. According to CSA Research, 76% of buyers prefer to purchase in their native language — but that preference builds trust only when the translated brand voice feels intentional, not generic.

SaaS products in DACH markets
A product expanding into Germany faces the Sie/du decision on every screen. Generic AI guesses based on the source text's formality signals — which produces inconsistent output across a UI. One screen says Sie, another says du, based on what the English text happened to suggest. The product reads as if it wasn't designed for German users.
The Brand Voice Manager locks the register across every string in the project. The product reads consistently — because the decision was made once at the configuration level, not inferred string by string.

Agencies managing multiple clients
Each client has a different voice. A legal services firm and a consumer app don't sound the same, and their translated content shouldn't either. A single workspace account holds a profile for each client — when a translator opens a project, the correct brand voice is already applied. The agency doesn't brief the AI separately for each project; the configuration does it.

Frequently Asked Questions
How does the Brand Voice Manager actually apply instructions to a translation?
+
The instructions you write in natural language are injected into the translation payload before the language model processes the source text. The model doesn't receive the text and a separate suggestion to apply a certain style — it receives both together as a structured input. The output is generated to those specifications from the first token. This is why the enforcement is consistent: the constraint was set before inference began, not checked against afterward.
Can I have multiple brand voices for different clients or projects?
+
Yes. Each account supports multiple Brand Voice profiles. You can create separate profiles for different clients, different content types (marketing vs. legal vs. UI strings), or different target markets. Profiles are assigned at the project or client workspace level — not per individual translation request. All content translated under a project inherits that project's assigned profile automatically.
Does the Brand Voice Manager control formality in languages with complex register systems?
+
Yes. The formality dimension is specified as a hard instruction in the brand voice profile — German Sie/du, French vous/tu, Spanish usted/tú, Japanese register levels. The model applies that setting as a constraint, not as a probabilistic inference from the source text. Mixed register output within a project doesn't occur because the instruction is part of the payload for every request in that project.
What's the difference between Brand Voice Manager and a style guide document?
+
A style guide document is a PDF or text file that a human translator reads and applies based on their interpretation. Consistency depends on how carefully the guide is written and how consistently it's followed — which varies across translators, sessions, and volume. The Brand Voice Manager is a configuration that's injected into every translation request automatically. No human has to read and apply it; the system does.
Can Brand Voice be combined with Glossary Enforcement?
+
Yes — and they work together. The glossary enforces specific terminology (product names, technical labels); the Brand Voice Manager enforces tone and register. Both are loaded before translation begins. A string can simultaneously be required to use the approved term 'Dashboard' and to use informal du register — both constraints are applied in the same pipeline step.
Does Brand Voice work across all 22+ supported languages?
+
Yes. The brand voice configuration is language-agnostic — the instructions are applied regardless of the target language. Formality-specific instructions (Sie/du, vous/tu) are language-aware by design: you specify the formality level, and the model applies the appropriate grammatical construct for the target language.
