Bad dialogue is easy to spot and hard to fix. It is the moment a reader’s eyes glaze over, the line that makes a scene feel like a school play. Good dialogue does the opposite: it disappears. You forget you are reading marks on a page and start listening to two people in a room. Getting there is not about having a magical ear for speech. It is about understanding what dialogue is actually doing on the page, and then cutting everything that gets in its way.
People rarely say what they mean
The single biggest mistake new writers make is treating dialogue as information delivery. A character wants to explain the plot, so they explain it, clearly and completely, in full sentences. Real conversation almost never works like that. People hint, deflect, change the subject, and answer questions that were never asked. They talk around the thing they care about most because saying it directly feels too exposed.
Consider a couple arguing about money. The weak version has one of them say, “I am upset because you spent four hundred dollars on a jacket when we agreed to save for the house.” That is a memo, not a fight. The stronger version might be a long silence, then, “Nice jacket.” Two words carrying resentment, sarcasm, and a whole history of broken agreements. The reader does the math. That gap between what is said and what is meant is where dialogue comes alive, because it gives the reader something to do.
When you draft a line, ask what the character is trying to get and what they are trying to hide. The tension between those two things shapes how they speak. A person asking for a raise is not just saying words about salary; they are managing fear, pride, and the risk of hearing no. Let that leak into the phrasing.
Read it aloud, every time
The fastest diagnostic tool you have is your own voice. Read every line of dialogue out loud, and you will immediately hear the sentences no human would ever say. You will notice where you stacked three clauses that no one could get through in one breath. You will catch the moment a character suddenly starts speaking like a textbook.
Speech has rhythm, and it is usually shorter and messier than written prose. People interrupt themselves. They trail off. They use contractions constantly, which is why “do not” instead of “don’t” can make a whole page feel stiff, unless the stiffness is the point. Reading aloud also reveals whether two characters sound different from each other. If you cover the dialogue tags and cannot tell who is speaking, you have one voice wearing two names.
Give each character a distinct way of speaking
Distinct voices do not require accents or dialect spelled out phonetically, which usually reads as a gimmick and slows everyone down. Voice comes from smaller, more durable choices:
- Sentence length. Some people speak in bursts. Others build long, winding sentences that circle back on themselves.
- Vocabulary and register. A retired engineer, a teenager, and a hospital chaplain reach for different words under stress.
- What they refuse to talk about. A character who deflects every serious question with a joke tells you who they are without a single description.
- Verbal tics used sparingly. One character who always says “look” before disagreeing, or who apologizes reflexively, becomes recognizable fast.
The key word is sparingly. A tic repeated on every line becomes a cartoon. Used once or twice per scene, it works like a fingerprint.
Cut the throat-clearing
Real speech is full of greetings, small talk, and logistics: “Hi, how are you, good, want some coffee, sure, milk?” On the page, most of that is dead weight. Fiction is not a transcript; it is a curated version of conversation that keeps the parts with charge and drops the rest. Enter scenes late and leave them early. You almost never need to show a character walking in and hanging up their coat before the real exchange begins.
The same goes for the tail end. Once the meaningful thing has been said, the scene is over. You do not need the polite wind-down. Cut on the strongest line and let the white space do the work.
Handle tags and beats with restraint
“Said” is nearly invisible, and that is a feature, not a flaw. Readers skim over it and stay with the conversation. The urge to replace it with “exclaimed,” “queried,” “opined,” and “chortled” comes from a fear that “said” is boring. It is not boring; it is transparent. Save the fancier verbs for the rare moment they genuinely change the meaning.
Better than a colorful tag is an action beat: a small physical gesture that grounds the dialogue and reveals emotion. Instead of “‘I’m fine,’ she said angrily,” try “‘I’m fine.’ She set the mug down harder than she needed to.” The action shows the anger and anchors the reader in the physical space at the same time. Beats also control pacing; a well-placed pause of action creates a beat of silence that a reader feels.
Let subtext do the heavy lifting
The best dialogue scenes usually have two conversations happening at once: the words, and the argument underneath the words. A scene about whether to order dessert can secretly be about whether a relationship is ending. Neither person mentions the relationship. They talk about the menu, the check, the drive home, and every line lands twice. Once you start building scenes this way, you will find you need fewer words, not more, because the reader is filling in the deeper layer themselves.
A practical way to build subtext: write the scene once with everyone saying exactly what they feel. Then rewrite it so no one is allowed to name the real subject directly. The second version is almost always the one worth keeping. The buried emotion pushes against the surface talk and creates pressure, and pressure is what keeps a reader leaning in.
Trust the reader
Underneath all of these techniques is a single principle: respect the reader’s intelligence. You do not need to explain the joke, spell out the emotion, or confirm that the sarcasm was sarcasm. Give people the raw material of a real exchange, keep your own hand off the scale, and let them draw the conclusions. Dialogue that trusts the reader is dialogue that sounds true, because that is exactly how we listen in life, always reading between the lines of what people are willing to say out loud.
