I get excited talking about this because the difference feels tiny on the surface but changes everything in a story. For me, narrative voice is the personality and tone that colors the whole telling — the word choices, the rhythm, the narrator's attitude toward events and characters. Think of the warm, naive cadence in '
To Kill a Mockingbird' versus the detached elegance in '
The Great Gatsby'; those are voices. They're about style: playful, ironic, lyrical, clinical, unreliable, intimate.
Narrator perspective, by contrast, is more logistical: who is doing the telling and what they can know. First-person, third-person limited, third-person omniscient, and even second-person are perspectives. The narrator might be a participant inside the story, a distant observer, or an interior focalizer who only shares one character's thoughts. So the voice is the flavor; perspective is the POV camera and its limitations. When I read, I notice voice first — it makes me feel at home — and then perspective shapes what secrets the story keeps from me. I find that mix is what makes a book feel singular.
