Have you ever read a line aloud from your second draft, only to hear it fall flat on the floor like a dead bird? Your characters speak in tidy, blameless sentences. They explain themselves. They never interrupt. Yet no voice rises from the page — only a polite, bureaucratic hum, as if two clerks were auditing each other’s grief.
This is the most common wound in revision, and almost no one names it. Today we will name it. And then we will cauterize it with a technique I call the Overheard Rule — a method of editing dialogue naturally by testing every spoken line against the merciless tribunal of a public room.
The Machinery of Mechanical Speech
Robotic dialogue is rarely caused by bad writing. It is caused by over-correction. In the first draft, you wrote with fever. In the second, you tidied. You made every sentence grammatical. You made every character articulate. In doing so, you murdered the one thing dialogue exists to carry: the sound of a specific nervous system.
Consider Edgar Allan Poe’s “The Cask of Amontillado.” Montresor lures Fortunato into the catacombs with chatter about wine, carnival, and a Masonic sign. None of it is efficient. All of it is dangerous. The dialogue works because it conceals intent — not because it advances plot in a straight line. Efficient dialogue is frequently dead dialogue.
Wound One: The Info-Dump in Disguise
The most frequent robot signal is exposition wearing a mouth. Characters repeat what the reader already knows, because you need the reader to know more. Meanwhile, in real rooms, people do not recap shared history. They allude. They trail off. They say “you know” and mean something enormous.
Watch for lines that contain a full name, a job title, or a date. Real humans almost never supply these to someone who already has them. As a rule: if the listener would not be surprised by the information, cut the sentence.
Wound Two: The Tyranny of Complete Sentences
Second drafts are haunted by grammatical completeness. Every reply begins with a subject and ends with a period. But speech is a ragged instrument. It fragments. It restarts. It breaks in the middle because the speaker has just remembered something worse.
Shirley Jackson understood this. In We Have Always Lived in the Castle, Merricat’s speech is half charm, half hex — sentences that shatter and reform. The reader trusts her instability precisely because her words refuse to hold still. Jackson never polished the cracks out; the cracks were the characterization.
Wound Three: The Attribution Tics
“She said angrily.” “He asked, his voice trembling with barely contained fury.” These are stage directions smuggled into the line itself. They tell the reader what the dialogue should have shown. Worse, they signal your own distrust of your characters.
Trust them. In Tana French’s In the Woods, conversational tension arrives through what is refused — questions not answered, jokes not made. The heat lives in the silence around the words, not in adverbs bolted to them.
Editing Dialogue Naturally: What the Ear Knows
Here, at last, is the remedy. It is simple, embarrassing, and devastatingly effective.
The Overheard Rule works like this: you take your dialogue to a public place — a café, a train car, a library lobby — and you read it aloud under your breath. Not in your study. Not in the safe dark of your own room. In the company of strangers. And you ask one question of every line:
If a stranger overheard this, would they believe a human being said it — or would they glance over and feel a small chill of wrongness?
Then you cut every line you would be embarrassed to overhear.
That is the entire law. And it will destroy roughly forty percent of your dialogue. This is a good thing. It is also why writers avoid it — the technique is a small funeral for sentences you loved. But grief, as you know, is where all good revision begins.
How to Practice the Overheard Rule
First, choose your arena. A café with moderate noise is ideal. Total silence makes you self-conscious. Total roar makes you careless. You want the ambient murmur of human speech beneath yours — a baseline against which your ear can calibrate.
Second, read at conversational volume, just under a whisper. This matters. Silent reading lets you hallucinate rhythm. Your inner voice forgives clunkiness that your mouth cannot.
Third, mark every line that produces one of three reactions: a flinch of shame, a involuntary pause, or the sensation that you are performing rather than speaking. These are your robots. Circle them without mercy.
Fourth — and this is the step most writers skip — listen to the room. Actually listen. Hear how a barista says “large or small” too fast. Hear how a couple argues about a train time in fragments, each sentence landing half a beat after its meaning. Real speech is fast, sloppy, and freighted. Let it recalibrate your sense of what is normal.
What to Cut, and What to Keep
The Overheard Rule does not mean writing nonsense. It means cutting the explanatory and preserving the revealing. Keep a stutter that exposes fear. Keep a non-sequitur that exposes avoidance. Cut the sentence whose only function is to inform the reader.
Gillian Flynn’s Gone Girl is a masterclass here. Amy’s monologues are polished — deliberately, psychopathically so. Nick’s speech is a slush of deflections. Neither is grammatical perfection. Both are terrifyingly human. Flynn knew that a character’s relationship to language is their personality.

Common Pitfalls When You Edit for Naturalness
Be warned. The ear has its own tyrannies. Three traps await the unwary.
The first is the over-correction into pure noise. Some writers hear “natural” and produce six pages of “um,” “like,” and weather talk. That is not realism. That is transcription. Fictional dialogue is compressed life — every word chosen to feel unchosen.
The second is dialect cosplay. Do not phonetically spell your characters’ accents until they become caricature. Daphne du Maurier achieved Cornish texture in Rebecca through rhythm and vocabulary, not through apostrophes. Let word choice carry origin. Let syntax carry class.
The third is forgetting that silence is a line of dialogue. Haruki Murakami and Jorge Luis Borges both understood that the most resonant exchange often contains a gap. A character who answers a different question entirely has spoken volumes. See also our exploration of using silence as a narrative instrument.
A Case Study: The Cartography of Silence
Allow me to demonstrate. Below is a scene from an original short work: a sister and brother, Nora and Elias, alone in their dead mother’s house at dusk, standing over a box of unsent letters. First, the dead draft — the version straight out of revision number two, dutiful and mechanical.
The Dead Draft
“Nora, as you know, our mother passed away three weeks ago, and I have been going through her things as the eldest son,” Elias said. “I found these letters, and I think you should read them, because they may explain why she never contacted Aunt Lorraine after the argument in 1994.”
“That is very interesting, Elias, but I am still grieving, and I do not think this is the right time to discuss family correspondence,” Nora replied sadly.
“I understand your feelings, but we must be practical, because the house has to be sold by the end of the month,” Elias explained reasonably.
Read that aloud in a café. Feel the flinch. Nobody speaks this way. The scene is two people delivering case files to each other. The grief is announced rather than suffered.
The Overheard Revision
Elias held the letters the way you hold something that might be wet. He did not offer them.
“There’s a lot,” he said.
Nora watched the light leave the hallway in increments. “How many.”
“Enough.” He turned one over. The postmark had gone soft as cloth. “She never sent them.”
“Well.” Nora picked up the kettle and set it down again without filling it. “She was like that.”
He looked at her then, and the look had edges. “You knew about Lorraine.”
“I knew about all of them.” The window had begun to rain, though the sky had been clear a moment before. “You want to sell by Friday.”
“That’s not —” He stopped. Somewhere below, a door shut in the empty apartment. “That’s not what I said.”
“It’s what you do.” She said it gently, which was worse. “You pack things up. Then you ask what they meant.”
Elias set the letters on the table. He arranged them square to the edge, because he could not bear the alternative. Outside, the rain thickened, and neither of them moved to close the window.
Notice what happened. Every piece of exposition evaporated. No death date, no deadline, no Aunt biography. Yet the reader now knows everything: the unsent grief, the sibling fault line, the different mourning languages. Nothing was explained. Everything was overheard.
For further exercises in this vein, study the technique pieces in show, don’t tell in dialogue.
The Linger After the Silence
Robotic dialogue is not a flaw of talent. It is a symptom of fear — the fear that if you do not explain, the reader will not understand. But understanding was never the point. Resonance is. And resonance lives in what is withheld, in the tremor beneath a two-word reply, in the sentence a character cannot bring themselves to finish.
So take your pages out into the cold light of a public room. Read them under your breath among strangers. And cut, without ceremony, every line that would make a stranger glance up and wonder who, in this quiet café, is speaking in the voice of no one at all.
For a broader survey of the revision mindset, see the art of ruthless self-editing. And when the noise of strangers has taught your ear its final lesson, ask yourself the only question that remains:
If no one in the world were listening, would your characters still dare to speak so plainly?
