Do you have a brand "voice"? If so, what makes it unique? Listen to your company's communications . . . are they clear? Consistent? Is your voice distinctive? Does it take the right tone for your company or organization?
Brand "voice" is the term we use for the way you talk to your clients or customers. This includes everything from the way you answer the phone, to the way you write emails, ads and brochures, to the way you and your employees communicate with clients face-to-face.
Some companies use a more casual voice, like a friend speaking to a friend. Others use more formal language and style to get their message across. It really depends on the type of company you are, what you're selling, and who you're selling it to.
