How to Write Brand Voice Guidelines (With Examples)

Brand voice guidelines are a short written document that defines how your business sounds in every message: the personality traits of your voice, the words you use and avoid, how tone shifts by channel, and real examples of good and bad copy. For a business working in Dari, Pashto and English, they also explain how that voice carries across languages. A practical guide fits on three to five pages and is something your team, freelancers and AI tools can actually follow.

Key Takeaways

• Define three or four voice traits, each with a "this, not that" explanation.
• Separate voice (who you are, constant) from tone (how you adjust to situations).
• Include before-and-after examples; they teach faster than rules.
• Write guidance for each language, not only English, including formality and forms of address.
• Keep the document short, share it widely, and review it once or twice a year.

What Is the Difference Between Brand Voice and Tone?

Voice is your brand's consistent personality; tone is how that personality adapts to the moment. A clinic's voice might be calm, clear and caring all the time, but its tone will be warmer in a welcome message and more direct in an appointment reminder. Guidelines should define the voice firmly and give flexible guidance on tone.

Without written guidelines, voice drifts. The owner writes one way on Facebook, a freelancer writes another way on the website, and a staff member replies on WhatsApp in a third style. Customers notice the inconsistency even if they cannot name it, and it weakens trust.

Why Do Small Businesses Need Brand Voice Guidelines in 2026?

Small businesses need them because more people and tools now write on their behalf. A typical Afghan business might have the owner, a part-time social media manager, a web developer, and AI tools such as ChatGPT drafting captions and replies. Each of these produces text, and without a shared reference they will sound like different companies.

Guidelines also help with AI writing. When you give an AI tool a clear description of your voice plus a few examples, the drafts it produces need much less editing. Our article on building an AI content marketing workflow shows how to plug your guidelines into that process.

What Should Brand Voice Guidelines Include?

A useful document covers a small number of sections, each with concrete examples. Include:

1. A one-paragraph brand summary: who you serve, what you offer and why people choose you.
2. Three or four voice traits, each with a short description and a "we are / we are not" line, for example "friendly, not overly casual" or "expert, not technical".
3. Vocabulary: words and phrases you prefer, words you avoid, and how you write your brand name, product names and key terms in each script.
4. Tone by situation: how you sound in social posts, website pages, replies to complaints, sales messages and urgent announcements.
5. Language-specific notes for Dari, Pashto and English.
6. Formatting basics: sentence length, use of emojis, and how you write numbers, dates and currency (AFN, USD, EUR).
7. Examples: real messages rewritten from "off-voice" to "on-voice".

How Do You Define Your Voice Traits?

Start from your customers and your strengths, not from adjectives you admire. Ask yourself: How do our best customers describe us? What do we want a new customer to feel after reading our website? How are we different from competitors?

A simple workshop works well. Gather the owner and anyone who writes for the business, collect 20 to 30 existing messages, and sort them into "sounds like us" and "does not sound like us". Look for patterns, then name the traits. Avoid generic traits such as "professional" on their own, because nearly every business claims that. Make each trait specific with a "not" line, because the boundary is what makes it usable.

For example, a "friendly" trait for a family restaurant might say: we greet people warmly and use simple words, but we do not use slang, and we never joke when a customer is complaining.

How Should Brand Voice Work in Dari, Pashto and English?

Your voice should stay recognisable in every language, but the way you express it must follow each language's norms. Write separate notes for each language rather than translating the English rules.

Points to decide include:

• Formality and forms of address. Dari and Pashto both distinguish a formal and an informal "you". Decide which you use with customers; most businesses use the respectful plural forms.
• Greetings and closings. Religious and cultural greetings are normal and expected in many contexts, but decide when they are appropriate.
• Vocabulary choices. Decide whether to use Afghan Dari terms or more Iranian-influenced vocabulary, and whether to keep technical terms such as "website" or "app" in English or adapt them.
• Humour and idioms. Jokes rarely translate. If humour is part of your voice, write it fresh in each language.
• Direction and layout. Remind writers that right-to-left text needs correct punctuation and that mixing Latin words into RTL sentences should be done carefully.

Keeping your name and its spelling consistent across languages is part of voice too. See our guide to brand naming in Dari, Pashto and English.

How Do You Make Sure People Use the Guidelines?

Guidelines only work if they are short, easy to find and part of daily work. Practical habits:

• Keep the core document to a few pages and link to it from your shared drive or team chat.
• Create ready-to-use templates for common messages: order confirmations, appointment reminders, complaint replies.
• Include the guidelines in the brief for every freelancer, designer and agency you hire.
• Save the guidelines as instructions in the AI tools your team uses.
• Review a sample of published posts and replies each month and update the examples.

Treat the document as a living reference. When you launch a new service, enter a new market or start a new channel such as TikTok, add a short section rather than rewriting everything. Your visual identity follows the same logic, as explained in the logo design process.
