What is Tone of Voice in Writing?
TL;DR: Tone of voice is the personality and emotion conveyed through word choice, sentence structure, and style. The same information can sound formal, casual, authoritative, friendly, or urgent depending on the tone used.
In marketing, tone of voice is a key brand differentiator. A bank might use formal, trustworthy tone while a startup uses casual, energetic tone. Consistency across all communications builds brand recognition and trust.
