Define voice through real examples, audience needs and editorial choices. Preserve meaning and evidence instead of optimizing for an AI detector.
A writing voice is a set of recurring choices, not a detector score. Make those choices explicit so that an assistant can support them without inventing your experiences.
Start with writing you actually endorse
Choose a few passages you wrote or have permission to use. Mark what works: direct openings, patient explanations, specific examples or restrained humor. Do not assume every quirk should become a rule.
Make a short voice card
Record the audience, level of formality, preferred terminology and examples of wording to avoid. Include a boundary such as “do not invent personal experience or customer results.”
Example voice card
“For readers fixing pasted text: give the action first, explain what changes, then show a limitation. Use ordinary words. Avoid claiming that cleanup makes text undetectable.” This guides useful decisions without demanding arbitrary sentence variation.
Compare versions against the task
Ask for a revision of one paragraph, then compare it with the original. Did it preserve the claim, qualification and intended emphasis? Reject a more fluent version if it changes the meaning.
Read the passage aloud when rhythm matters. Have an intended reader explain what they understood; that can reveal ambiguity that a style checklist misses.
Keep style and verification separate
A friendly sentence can contain a false claim. Review facts and sources independently of voice. Google's people-first guidance asks about trust and value, not a compulsory informal tone.
Finish with bounded cleanup
Use formatting cleanup when copied markup obscures the wording. Use the spacing tool when repeated spaces or blank lines are the actual problem. Neither operation creates a personal voice or verifies authorship; keep the final editorial decision with the writer.
