Brand voice is how your brand sounds — in emails, ads, social, support. Here’s how to define one that’s distinctly yours.
Voice vs Tone
Voice is your brand’s personality — it doesn’t change. If your voice is ‘direct, knowledgeable, occasionally wry,’ that’s true in every channel. Tone is how voice adapts to context: warmer in a welcome email, crisper in an error message, playful in social, respectful in customer support for a frustrated user. Define voice once; let tone flex.
How to Find Your Voice
Pick 3–5 voice attributes: adjectives that describe how your brand communicates. Good sets: ‘confident, direct, humorous, pragmatic.’ ‘Warm, expert, optimistic, candid.’ Avoid generic: ‘friendly, professional, innovative’ describes every brand. Better attributes are slightly contradictory (‘expert but approachable,’ ‘serious but not stuffy’). Tension creates distinctive voice.
Voice in Practice: Do’s and Don’ts
For each voice attribute, write do/don’t examples. ‘Direct’ means: say what you mean in plain language; don’t bury value in jargon. ‘Humorous’ means: occasional wit in unexpected places; don’t force jokes that fall flat. Concrete examples are more useful than abstract rules. Every brand guideline should include side-by-side: ‘On-brand’ / ‘Off-brand’ examples from real copy.
Word Choice Lists
Define: words we always use, words we never use, industry jargon to avoid, terms that signal membership vs outsider. Example: ‘Customer’ vs ‘user’ vs ‘client’ changes the feeling entirely. ‘We’ve built’ vs ‘We’ve created’ feels different. Precise word lists save new writers hours of guessing — and create consistency across dozens of contributors.
Why Most Brands Have Inconsistent Voice
Typical company: CEO writes thought leadership, marketing writes ads, support writes macros, product writes in-app copy — all in different voices. Users feel the incoherence even if they can’t name it. Fix: document the voice once, distribute to everyone who writes customer-facing content, run quarterly voice audits on live copy. The work is in the maintenance, not the initial guidelines doc.
Voice Over Time
Voice should evolve slowly. Dramatic voice pivots (jokes overnight, or sudden formality) feel jarring. Audit voice annually: are the attributes still right, is the voice still distinctive in your space, are new competitors encroaching on your territory? Small adjustments over years drift your voice in the right direction; sudden changes signal instability or rebrand.
