Tone of voice
Tone of voice is the way a company sounds whenever it writes or speaks: how formal, serious, respectful and enthusiastic it is, and which words it uses and avoids. It stays the same company while adjusting to the reader and the moment.

What it is
Tone of voice covers choices a reader notices without naming them: how long the sentences are, how much jargon gets through, whether the company says “we”, whether it jokes, how it apologises. Nielsen Norman Group describes tone on four scales: formal to casual, serious to funny, respectful to irreverent, and matter-of-fact to enthusiastic. A company picks a point on each.
Many teams split the term in two. The voice is the constant part, the personality that makes a line sound like this company. The tone shifts with the situation: a welcome email can be warm, and an outage notice or a declined payment calls for something plainer. A voice guide records both, usually as examples of what to write and what to avoid.
Why it matters
Tone changes how far people trust what a company says. In a Nielsen Norman Group study, a playful version of some insurance copy was rated friendlier than a serious version and less trustworthy, and trust predicted whether people would recommend the company far better than friendliness did. Without a written voice, each writer falls back on their own, and the homepage, the sales deck and the support reply sound like three different companies.
How we do it
We write the voice down after the position is agreed, because how a company sounds follows from who it is for. In a positioning sprint it comes out as a voice guide with examples that run from a homepage headline to a support reply, so someone who missed the sessions can write in it.
The fuller voice and narrative work adds a voice spec. Each entry gives a line to write, a line to avoid and the reason for the difference. We test the lines on your homepage, in the deck and on sales calls, then rewrite your homepage hero to match. The documents are yours, and your own writers can work from them.
An example
Say a company sells invoicing software to tradespeople, and its guide sets the voice as plain and warm, with no jokes about money. The welcome email reads “You’re set up. Send your first invoice from the job site.” When a batch fails, the voice holds and the tone drops the warmth for facts: “Yesterday’s invoices didn’t send, so your customers haven’t received them. We’re resending them now and will email you by 3pm.”
Common mistakes
- Describing the voice in adjectives. Friendly, confident and clear fits almost every company, so a guide needs example lines, each with the version to avoid beside it.
- Writing the voice before the position. How a company sounds follows from who it is for, so a voice written before that is agreed tends to be rewritten afterwards.
- Sounding like the category. If every competitor sounds urgent and futuristic, a company that sounds the same gives the buyer nothing to remember it by.
- Filing the guide where nobody writes. Put the examples where the next line gets written: the content management system, the support macros and the product’s interface text.
Tone of voice vs messaging
Tone of voice is how a company’s sentences sound whoever writes them, and messaging is the set of claims it makes, ordered by what a buyer has to hear first.
| Tone of voice | Messaging | |
|---|---|---|
| Settles | How we say it | What we say |
| Follows from | Who the reader is | The positioning |
| Written as | Lines to write and lines to avoid | Claims in order, with proof for each |
| Changes with | The moment and the channel | The audience and the offer |
Questions
What people ask about tone of voice.
Voice is the constant part of how a company sounds: its personality, which should be recognisable in every piece of writing. Tone is how that voice adjusts to the moment and to the reader’s state of mind. A company keeps the same voice in a launch email and an apology, and uses a different tone in each.
Nielsen Norman Group describes four: formal to casual, serious to funny, respectful to irreverent, and matter-of-fact to enthusiastic. Each is a scale, and a company’s tone of voice sits at a chosen point on each one. The scales help a team agree what “friendly” means before anyone writes a line.
A short description of how the company sounds, then worked examples. The useful ones pair a line to write with a line to avoid and give the reason, across the places people write: the homepage, a sales email, an error message and a support reply. Include bad news as well as good.
