How to define the tone of voice of an AI assistant
Create a conversational style guide with examples so replies sound consistent with your brand.
In a nutshell
A good tone isn't just “friendly.” It defines wording, length, level of formality, use of emojis and how to handle doubts, limits and complaints.
Choose three observable attributes
Use attributes you can see in a reply, such as direct, warm and clear. Avoid piling up adjectives that contradict each other.
For each attribute, write what it means and what it doesn't. Warm may mean greeting someone by name, but not using cutesy language in a complaint.
- Level of formality.
- Typical length.
- Formal or informal address.
- Emojis and punctuation.
Create examples by situation
The same brand speaks differently when sharing opening hours than when answering a complaint. Prepare examples for greetings, inquiries, missing information, mistakes and handoffs.
Show preferred replies and versions to avoid. The contrast makes the guide much more concrete.
- First reply.
- Asking for data.
- Nothing available.
- Handoff to a person.
Don't sacrifice clarity
Tone supports the content; it shouldn't hide conditions or fill the reply with promotional phrases. In messaging, one idea per block is usually easier to read.
If the conversation needs several steps, explain what is needed now and what will happen next.
- Short sentences.
- Lists only when they help.
- No internal jargon.
- Close with a clear action.
Review real conversations
Read samples from different times and topics. If the assistant repeats greetings, uses expressions the team would never use or sounds overconfident, adjust the rule with a concrete example.
Volga combines the behavior guide with business knowledge and lets you hand off without losing the history.

- Empathy in sensitive cases.
