"You’ve probably heard that one quality found in good writing is voice. Voice refers to elements of the author’s tone, phrasing, and style that are recognizably unique to her or him. Having a distinctive, persuasive voice is crucial to engaging your audience — without it, your paper risks falling flat, no matter how much research you’ve compiled or how well you’ve followed other directions."

An example of two distictive authors with their own unique style in writing could be Dante Alighieri's writing vs Shakespeare. Both have a sense of formal, poetic style but you can still differentiate their writing because of their use of phrasing.
