Tone of Voice: How to Define It and How to Keep It
Tone of voice isn't a matter of style. It's what makes your message recognisable when different people write it.
Every company already has a tone of voice, even when it has never defined one. The problem is that it changes with the writer, the channel and the mood of the day. Defining it means making it stable.
Define it with axes, not adjectives
Saying 'we want to be professional but friendly' helps nobody write. It works better to position yourself along concrete axes, stating where you sit between two extremes.
- Formal versus conversational.
- Technical versus accessible.
- Understated versus emphatic.
- Direct versus cautious.
Examples are worth more than definitions
For every recurring situation it pays to write two versions of the same sentence: the correct one and the one to avoid. It's the fastest way to convey the register to someone joining a project without knowing its history.
Situations to cover
- Introducing a service.
- Replying to a quote request.
- Handling criticism.
- Communicating a delay or a problem.
What to always avoid
The most useful guidelines contain a list of don'ts: inflated expressions, automatic superlatives, unverifiable promises, technical jargon used to impress. These are the habits that erode credibility without anyone noticing.
Review over time
Every few months it's worth rereading what was published and asking whether it sounds like the same voice. If it doesn't, the problem usually isn't the document: it's that nobody has opened it in a while.
