Tone of voice in communication, especially in branding and marketing, refers to the personality and emotion infused into a company’s communications. It encompasses not just what is said, but how it is said, and is a critical element in establishing a brand’s identity and connecting with the audience. A consistent tone of voice helps build trust, differentiates a brand from its competitors, and influences how the audience perceives the brand.

For instance, a youth-oriented brand might adopt a casual, energetic tone in its communications, while a law firm might opt for a more formal and authoritative tone.
