Strengthening brand identity: How to build a Voice and Tone guide

Learn how to create a voice and tone guide to ensure consistency and strengthen your digital product’s communication

Have you ever wondered how brands and digital products manage to communicate in a unique and consistent way across all channels? In large companies, dozens — if not hundreds — of people communicate on behalf of the brand.

How do all these people know which words to use? How should they sound? The secret lies in the voice and tone guide.

A voice and tone guide acts as a compass, defining how the brand should speak to its users and ensuring that communication always reflects the same personality. It helps different teams — such as UX Writers and Content Designers — create consistent experiences that make sense at every touchpoint of a product.

What are Voice and Tone?

Before we dive in, let’s clarify an important point: do you know the difference between voice and tone?

• Voice is stable. It represents the brand’s identity, values, and personality. It remains unchanged regardless of the situation or channel and allows the brand to be instantly recognizable, communicating its values clearly and consistently.
• Tone is flexible. It adjusts according to context, audience, and specific situations. For example, an error message and a promotional message will differ in tone, as tone adapts the voice to deliver the message in the most appropriate way for the moment.

Think of voice as a person’s personality: it is unique and constant, no matter where or with whom they are speaking. But tone is how that voice shifts in different contexts — it adapts to the situation.

For example, I am Stephanie in this newsletter, with my wife, and among friends. But I wouldn’t speak to the company’s CEO the same way I would to my brother. It all depends on the scenario and the need!

The importance of a Voice and Tone guide

As mentioned earlier, a voice and tone guide serves as a compass to maintain communication consistency. It ensures that no matter who is creating the content, the brand’s messaging always carries the same personality and represents its values.

When used effectively, this guide helps users recognize and connect with the brand at any touchpoint — whether in an app, website, or social media. It aligns internal teams, ensuring that everyone — from marketing to product development — knows how the brand should express itself in different situations.

It defines style, the types of words to use or avoid, and ensures communication resonates with the target audience while preserving the brand’s unique identity.

However, a voice and tone guide is not a set of rigid rules. It is a living document that needs to evolve with the audience and circumstances.

Why do you need a Voice and Tone guide?

In UX Writing, the way we communicate with users can shape their entire experience with a product. Confusing messages lead to frustration.

On the other hand, clear and consistent communication flows like a good conversation. That’s where a voice and tone guide comes in — it reduces friction and makes interactions smoother and more enjoyable.

This guide isn’t just for UX Writing teams. As mentioned earlier, it’s useful for everyone — designers, developers, marketing teams, and customer service. It provides a unified communication strategy so that even with new team members or different departments interacting with users, the brand maintains the same voice.

The best part? A voice and tone guide is a living tool that evolves as the brand and product do. In companies with multiple teams, this is crucial to keeping communication aligned and coherent.

How to create a Voice and Tone guide

Defining a brand’s voice is like defining its essence. It starts with a deep understanding of the company’s values and mission — not just what the brand does but how it wants to be perceived.

A practical way to begin is by listing adjectives that capture the brand’s personality. For instance, a brand might want to be known as “innovative,” “playful,” and “approachable.” These traits then guide all communication.

But defining voice and tone isn’t just the job of UX Writers! All teams should collaborate, as each one interacts with users differently and can offer valuable insights on adjusting tone for various scenarios.

A great technique for defining tone is creating scenarios that represent different user emotions. How would the brand communicate with someone feeling frustrated? Or a happy customer?

These simulations help teams understand how to adapt communication for each context, ensuring the tone always fits the moment.

And to keep the guide aligned with reality, research plays a key role. This includes internal research with teams and stakeholders, as well as user research to understand how the brand is perceived and how communication should be adjusted.

Steps to build a Voice and Tone guide

Creating a voice and tone guide is a long, detailed process that requires attention and dedication. It’s not something you’ll finish in a week or two.

To begin, consider these essential steps:

1. Analyze Existing Content: Map out all existing content and identify language patterns, strengths, and areas for improvement.
2. Research Your Audience: Conduct research and usability tests to understand user behavior, preferences, and expectations. This ensures that voice and tone align with audience expectations.
3. Define the Brand’s Personality: Gather the team to choose adjectives that best describe the brand, such as “friendly,” “innovative,” or “inclusive.” These characteristics shape the brand’s communication style.
4. User Testing: Once the guide is structured, test it with users to ensure that communication works as intended and the brand voice is perceived correctly.
5. Align with Brand Mission and Values: Ensure that the brand’s voice reflects its core principles.
6. Adapt Tone to Different Contexts: Since tone is flexible, adjust it based on the channel and situation. A LinkedIn post, for example, will likely be more formal than a Twitter reply.
7. Create Interaction Scenarios: Define communication approaches for different emotional states — frustration, happiness, curiosity — to ensure tone is appropriately adapted.

Essential elements of a Voice and Tone guide

To be truly useful, a voice and tone guide should include:

• Grammar Guidelines: Rules on punctuation, capitalization, and writing style to maintain consistency.
• Words to Use and Avoid: A list of words that align with the brand’s identity and those to avoid, especially if they are offensive or inappropriate.
• Practical Examples: Real-world examples of how the brand should communicate across different platforms and situations.
• Voice Description: A clear explanation of the brand’s personality.
• Tone Variations: How tone changes depending on context and audience.
• Scenarios and Examples: Communication examples for different situations, such as celebrations or crisis management.

A well-structured voice and tone guide not only directs but also simplifies communication efforts, ensuring alignment across teams and a seamless connection with users.

TL;DR

A voice and tone guide helps teams maintain a unified brand voice and communication consistency.

• Voice: The brand’s stable identity that reflects its values and personality.
• Tone: The adaptable aspect that changes depending on the context and situation.
• A dynamic tool: It should be updated as the brand evolves.
• Steps to create: Analyze existing content, research audience expectations, define brand personality, test with users, align with brand mission, and adapt tone.
• Key elements: Grammar guidelines, approved vocabulary, practical examples, voice description, tone variations, and real-world scenarios.
