Brand voice
The consistent personality in how you write: word choice, sentence rhythm, what you refuse to say. Distinct from tone, which shifts by context.
In depth
What it really means
Voice is constant, tone moves. Your voice is the same in a pricing page and an outage notice. The tone differs: one is confident, the other is direct and apologetic.
Most brand voice documents fail because they list adjectives. Being told to sound ‘confident but approachable’ helps nobody. A useful voice guide shows before and after sentences, and names the words you do not use.
How it works
- Collect writing your team already thinks sounds right.
- Identify the concrete patterns: sentence length, contractions, jargon tolerance, humour.
- Write the never list, which is more actionable than the always list.
- Show before and after rewrites for each principle.
- Apply it to AI-assisted drafting, which flattens voice by default.
Pros & cons
Pros
- Makes content recognizable across many writers.
- Speeds up editing, since standards are explicit.
- Differentiates in categories where everyone sounds identical.
Cons
- Hard to define without becoming vague.
- Enforcement takes editorial time.
- Too strict, it flattens individual expertise.
Common mistakes
- Adjective lists with no examples, which cannot be applied.
- No never list, so the guide only says what to aim at and never what to avoid.
- Ignoring AI drafting, which regresses everything toward the same neutral register.
- Voice guidance that contradicts how your best writers already write.
- Enforcing voice on subject matter experts to the point they stop contributing.
Best practices
- Show before and after sentences for every principle.
- Write an explicit never list of words and constructions.
- Build the guide from writing you already like, not from aspiration.
- Include it in AI prompts, since default model output has no voice.
- Let expert contributors keep their own register within the boundaries.
FAQs
What is brand voice?
The consistent personality in your writing: word choice, rhythm and the things you refuse to say. It stays constant across contexts.
Voice or tone, what is the difference?
Voice is constant, tone adapts to the situation. Same voice in a launch announcement and an incident report, different tone.
How do I document brand voice usefully?
With before and after sentence rewrites and an explicit never list. Adjective lists like ‘confident but approachable’ cannot be acted on.
Does brand voice matter with AI drafting?
More than before. Default model output converges on the same neutral register, so an explicit voice guide in the prompt is what keeps drafts recognizable.
Should every writer sound identical?
No. Aim for recognizable rather than uniform. Flattening subject matter experts into one register usually costs you the expertise that made them worth publishing.
