It’s the distinct personality we use to speak with its audience across all mediums. It has characteristics (such as intelligent, inquisitive, approachable, etc.) that influence word choices and phrasing across all communications. Similar to how a person may adjust their word choice to match a situation (without deviating outside of their core personality), the brand voice should have enough complimentary characteristics to create a harmonized voice that has the flexibility to adapt appropriately to the communication needs of the moment.
Brand Tone is less about the characteristics of the words we choose and more about the inflection in which they are spoken or written. The tone of voice adds feeling and depth to our message. By adjusting the tone of voice, one message can have many possible inflections.
This guide helps align your brand so that communications are cohesive in both voice & tone across all communications - written and spoken.
