Voice quirks aren't bugs — they're the only thing AI cannot replicate

By Dave Harland · Founder The Word Man; copywriter for Emirates, Jaguar, Nespresso, Red Bull, BBC · 2026-03-03 · essay · Dave Harland — write like YOU speak (operator synthesis)

Tier B · TL;DR
Voice quirks aren't bugs — they're the only thing AI cannot replicate

Claim

"Write like YOU speak. Not how people generally speak, but how you specifically speak." Specific verbal tics, rhythms, analogies, and odd references are assets, not liabilities. In a market where most B2B copy is interchangeable, distinctive voice is the primary conversion mechanism — and it's the ultimate anti-AI signal because AI cannot replicate one specific person's voice.

Mechanism

Most copy advice flattens to "write conversationally," which produces generic conversational copy. Harland goes one level deeper: write your conversation, not the abstract median. Dollar Shave Club worked because it sounded like one specific guy who found the razor industry absurd. The voice was inseparable from the brand. Companion rule: people don't want to know how proud you are of your company — they want to know how you'll change their life. Every sentence starting with "We are proud to…" is about the company; delete and rewrite from the reader's perspective.

Signals

Counter-evidence

Multi-author content teams (HubSpot, Atlassian) deliver scaled SEO traffic with deliberately neutral, consistent voice. Voice-as-moat depends on a specific person staying with the brand; founder-voice strategies break when the founder leaves.
