1. Conversational role
Decide who the brand is for the audience in the moment: guide, practitioner, curator, partner or quiet expert. Choose the role from the communication job, not simply from the founder’s personality. The role should clarify what the brand notices and how it helps.
2. Distance and rhythm
Document formality, address, sentence length, emotional range and pace. Informal language is not automatically warm, and short sentences are not automatically bold. Add two paragraph examples so an editor can hear the intended rhythm.
3. Ownable language and boundaries
List terms the brand uses precisely and patterns it avoids: hype, pressure, bureaucracy, childish language or unexplained jargon. Every prohibition needs a preferred replacement. Otherwise the team only knows what not to write.
4. Behavior under pressure
Show how the voice handles a mistake, refusal, price increase and negative review. These situations turn tone of voice from aesthetic preference into an operating standard.
