Definition
Voice is the consistent personality of a brand's writing — its values, perspective, and verbal mannerisms — held constant across contexts. Tone is how that voice shifts to match the moment: warmer in onboarding, calmer in errors, sharper in launch announcements.
Voice is who the brand is when it writes; tone is how it speaks given the situation. A brand with a confident, dry voice still uses a softer tone when apologising for an outage and a louder tone when launching a product. The voice doesn't change; the dial moves.
Defining voice is harder than it looks. "Friendly, professional, innovative" describes every brand and therefore none. Useful voice definitions are specific enough to reject things — "we never use exclamation marks," "we don't capitalise feature names," "we say 'people' not 'users'." Specificity is what makes a voice consistent across writers.
Origin
Editorial voice has existed as long as publishing. The application to brand writing matured through the 2010s, with MailChimp's public Voice & Tone guide (2012) the most-cited modern example.
How it works
- Define 3–5 voice principles with examples ("clear, not clever"; "confident, not boastful").
- Document the dial — what tones appear in what contexts (onboarding, error, success, marketing).
- Write "we say / we don't say" pairings to make the rules concrete.
- Cover concrete usage — capitalisation, punctuation, contractions, oxford comma.
- Provide before/after examples — same idea, in-voice vs. out-of-voice.
- Audit existing copy against the new guidelines; rewrite the worst offenders.
When to use it
Use when
- Whenever the brand writes — and that's everywhere: web, app, email, ads, support, social.
- When multiple writers contribute to the brand and the writing reads as a committee.
- When entering a new market or audience that demands tonal adjustment.
Skip when
- As a generic adjective list ("friendly, professional, innovative"). Specificity or it's worthless.
Key metrics
- Reader sentiment across surfaces (NPS, survey).
- Audit pass rate — does new copy follow the guidelines?
- Consistency across writers (blind test — can you tell who wrote what?).
Examples
- The voice is direct and dry; the tone in onboarding is warmer than in legal copy.
- Without a defined voice, every team writes in their own style and the brand reads as a committee.
- We rewrote 80 microcopy strings to match the new voice — comprehension scores went up.
In practice at Makreate
Makreate Branding engagements include voice and tone guidelines so the brand sounds like one person across every channel. On a recent B2B SaaS engagement we shipped a 12-principle voice doc with 40 before/after pairings; six months later the marketing team, support team, and external writers all produce copy that reads as one writer — even when they're not in the same room.
Branding →Common mistakes
- Generic adjective lists. They describe nothing.
- Voice without examples. Writers need to see the principles applied.
- Forgetting tone — voice is constant, tone shifts; without that distinction the brand sounds robotic.
- Documenting only marketing voice and forgetting product voice (UI copy, errors, system messages).
- No audit + rewrite of existing copy. New voice + old copy = mixed signal.
Frequently asked
Voice or tone first?
Voice first — it's the foundation. Tone variations come from the same voice; defining tone before voice produces inconsistency.
How long should a voice doc be?
20–60 pages or screens for a full voice + tone guide with examples. Shorter docs lack the specificity writers need; longer docs don't get used.
Who owns voice?
A named owner — usually a brand, content, or marketing lead. Without an owner, voice drifts.
