How to define your tone of voice: fixing your brand voice in 5 steps

Many brands jump straight to writing rules: use “you”, avoid jargon, keep sentences short. Useful, but that is the finishing touch, not the starting point. Defining your tone of voice is first of all a strategic question: who is your brand if it were to speak? Only once that is settled do writing rules mean anything. In this article you will read how to build and fix your brand voice starting from your brand personality, so that every text, from a quote to a LinkedIn post, sounds recognisably like you.

What exactly is tone of voice?

Tone of voice is the consistent personality with which your brand communicates. It is the difference between what you say (your message) and how you say it (your voice). Two companies can offer exactly the same service and still sound completely different: one down-to-earth and direct, the other warm and encouraging. That “how” layer is your tone of voice.

An important distinction: your brand voice is not the same as your content style guide. The style guide fixes the execution, think spelling, capitalisation, punctuation and terminology. The tone of voice fixes the personality underneath it. The style guide tells you to write “e-mail” with a hyphen. The tone of voice tells you whether your customer has a “challenge” or a “problem”. That second one is a brand choice, not a language rule.

That is why tone of voice belongs in your brand strategy and not in the agreements with your copywriting agency. A voice that stands apart from who your brand is becomes arbitrary. A voice that grows out of your positioning and values strengthens everything you publish.

Why your brand voice grows out of your brand strategy

A tone of voice you stick on top of an existing brand always feels borrowed. It does not hold up as soon as several people start writing. The reason is simple: a voice is an expression of character, and character comes from your brand foundation.

Three elements feed your brand voice directly:

• Your brand values. If “honesty” is a core value, your brand also says when something is not worth it. If “ambition” is central, you sound more outspoken. So start by defining your brand values before you work on your voice.
• Your positioning. Do you want to be the accessible challenger or the established expert? That changes your entire register. The challenger can be sharper and more playful, the expert sounds calmer and more assertive.
• Your audience. A voice has to resonate with the people you want to reach. You address a board differently than an operational team, even though your brand character stays the same.

How to define your tone of voice in 5 steps

This is where you make it concrete. These five steps take you from a vague feeling to a brand voice everyone in your organisation can apply.

Step 1: Describe your brand personality

Start with character, not with language. Picture your brand as a person at a networking event. How does it behave? Is it the calm expert who only speaks when it matters, or the energetic connector who introduces everyone to each other? Write down three to five personality traits, for example “down-to-earth, helpful, self-assured, slightly stubborn”.

A handy technique: pick a few well-known brands or people who hit the tone you are after, and name why. This forces you to make choices and stops you from getting stuck at “professional and reliable”, which is literally what every brand says about itself.

Step 2: Translate personality into voice dimensions

Personality is still too abstract to write down. Make it measurable with dimensions your brand takes a position on. Place your brand on a scale each time:

• Formal ↔ informal
• Serious ↔ playful
• Down-to-earth ↔ enthusiastic
• Modest ↔ outspoken
• Respectfully distant ↔ friendly

By deliberately picking a point on every scale, you force direction. “Rather informal, clearly down-to-earth, moderately outspoken” is something a writer can work with. “Good tone” is not.

Step 3: Make it tangible with do’s and don’ts

A dimension only becomes usable once you show what it means in real language. Work out a few do’s and don’ts per dimension, with example sentences. For example, for a down-to-earth voice:

• Do: “This channel is not paying off for you. We would put the budget elsewhere.”
• Don’t: “We unburden you with a 360-degree omnichannel approach that maximises your synergy.”

Those contrasts make abstract choices instantly recognisable. They are also the part colleagues consult most often, because they show directly what a sentence does and does not look like.

Step 4: Test against context and register

One flat tone for everything does not work. Your voice stays the same, but your register adapts to the situation. An error message should not contain a joke, a congratulations email deserves exactly that bit of warmth. So describe how your brand sounds in different situations: with good news, with bad news, on a sales page, in support. That way you avoid your voice feeling inappropriate at the wrong moment, while the character stays recognisable.

Step 5: Document and share

A brand voice that lives in someone’s head disappears the moment that person leaves. Capture everything in a short, workable document: your personality traits, the voice dimensions, the do’s and don’ts and the example sentences. Keep it practical and short enough that people actually use it. This document is not a finishing touch but a working tool, so share it with everyone who writes for your brand, from marketing to sales to support.

Keep your brand voice consistent across channels

Fixing your voice is half the work. Keeping it alive is the other half. Consistency usually does not break down at the marketing department, but at the edges: a quote that sounds like a legal document, a support reply that is too stiff, a job ad that suddenly turns corporate. That is exactly where your audience decides whether you come across as credible.

Three things help you hold the tone:

• Onboarding. Have new employees and freelancers read the voice document before they publish.
• Examples over rules. People remember a good example sentence better than an abstract guideline. Collect strong texts as reference.
• Periodic check. Every now and then, read a cross-section of your communication and ask: does all of this sound like the same brand? If not, correct course.

A consistent voice strengthens every other brand component. How you sound and how you look should form one whole, which is also the reason why developing your brand identity and your tone of voice ideally happen in the same track.

Frequently asked questions about defining tone of voice

Is tone of voice the same as a style guide?

No. Your tone of voice fixes your brand’s personality: warm or down-to-earth, playful or serious. A style guide fixes the execution: spelling, capitalisation and terminology. The voice steers the choices, the style guide handles the details.

Who should define the brand voice?

It is a strategic choice, so involve the people who know the brand best: founders or management, marketing and ideally someone with customer contact. It should not be the isolated exercise of one copywriter, because the voice has to hold across the entire organisation.

How many voice dimensions do I need?

Four to six works well. Enough to give direction, few enough to stay manageable. More dimensions make the document precise, but harder to apply in practice.

Get started with your brand voice

Defining your tone of voice is not a writing exercise but a brand choice. Start with who your brand is, translate that into concrete dimensions, and make it tangible with examples anyone can follow. A voice that grows out of your strategy makes every text recognisable and strengthens your whole brand, post after post.
