How to Write Dialogue So Characters Sound Different

Why dialogue in fanfic is more than just conversation

Here's something I notice right away with newer writers: every character sounds the same. Same sentence length, same vocabulary, the same "he said" after every line. You read it and can't tell who's speaking if you cover the names.

Well, that's fixable. Pretty quickly, once you know where to look.

Dialogue in fanfic does three things at once: it reveals character, moves the plot, and sets the pace of the scene. If it only does one of those — readers feel it as a lull. So I'd suggest thinking about dialogue not as "what the character says" but as "how they say it and what they're NOT saying."

Character voice: making sure everyone sounds like themselves

Honestly, the best way to hear the difference is to imagine you've removed all the names and dialogue tags. If you still know who's speaking — great. If not — there's work to do.

Character voice has several layers:

• Vocabulary. An eighth-grader doesn't say "de facto" and "a priori." An aristocrat doesn't shorten words to their most casual form. A street-level con artist doesn't quote Shakespeare (unless that's a deliberate character quirk you've set up).
• Sentence length. An anxious person speaks in short bursts. Someone who loves to tell stories goes on in long, winding sentences with tangents. A quiet introvert keeps it minimal — and every word counts.
• Topics a person avoids. This is actually the most interesting part. Someone afraid to admit they're in love will talk about everything else: the weather, tomorrow's plans, the neighbor's cat.
• Verbal tics and patterns. Some people answer every question with a question. Some drop "actually" before anything important. Readers won't consciously clock these — but they'll remember the voice.

Subtext: what's really happening between the lines

Look, most real-life conflicts aren't fights about the fight itself. Two people argue about dirty dishes — but really about one of them feeling ignored. Two friends discuss weekend plans — but one wants an apology she never got.

Subtext is the gap between what's said and what's meant. That's where tension lives.

How do you write it in? Simple technique: write the "direct" version first, where characters say exactly what they think. Then rewrite it so they're trying NOT to say the main thing. You'll see how much more interesting it gets.

"Did you know?" — "Know what?" — "Don't." Three lines, zero explanation, but you feel the whole iceberg.

If you want to practice — try writing a scene right in the Fanficia generator: set the genre to romance, describe the characters, and see what dialogue comes out.

Rhythm: how sentence tempo changes the feel of a scene

This is where the text editor actually fails you. Dialogue rhythm isn't what you see — it's what you hear. That's why I always say: read your dialogue out loud.

Fast rhythm — short lines, minimal description between them, action verbs:

— Where is he?
— Gone.
— When?
— Five minutes ago.

Slow rhythm — longer sentences, more pauses, description of the character's state between words:

"I don't know how to explain it," she said finally, looking out the window. "It's just... I thought I'd understand when the time came. And the time came, and I still don't."

Both are right — depending on the scene. The problem is when everything sounds the same.

"Said" and when to let it go

So, the classic question: is "said/asked/replied" fine, or is it lazy?

Answer: neutral tags (said, asked, replied) are invisible glass. They don't distract. That's their power — you don't need to replace every "said" with "growled" or "whispered anxiously."

But sometimes you don't need a tag at all. If you place a character's action between the lines — the action becomes the tag:

He set the book down. "Are you serious?"

The reader knows who's talking. No "he said" required. This technique — the "beat" — marks the speaker and shows their reaction at the same time. Use it instead of tags wherever the action matters.

I wrote more about scene structure in "First Scene of a Fanfic" — it covers how to open a chapter. And if you want to see how romantic dialogue works in context, check out the romance section of the Fanficia library to see how other writers handle it.

The mistakes I see most often

Before we get to questions — a few concrete things to check in your own writing:

• All characters use the same filler words and clichés.
• Every line has a tag with an adverb: "he said sadly," "she replied sharply." Adverbs here are usually deadweight — show the action instead.
• Characters explain things to each other that both of them already know. This is called "maid and butler dialogue" and it kills immersion instantly.
• Dialogue is too polite: nobody interrupts, nobody changes the subject, nobody talks over anyone. Real conversations are messier than that.

Want to check whether your dialogue is working? Try editing your draft with this checklist in mind.

A concrete example: one scene, two voices

Let me show how the same moment changes depending on the character. Picture a scene: two people standing in front of a locked apartment door, waiting. The first is composed, controlled, used to running things. The second is anxious and talkative, hiding nerves behind words.

Version A (first character):

"Late," he said. "I know," I said. "But he was supposed to be here at nine." "Was."

Three lines. He adds nothing extra. Each word carries weight.

Version B (second character in the same scene):

"Do you think he already left? Or maybe he's still on his way? I texted him but he hasn't read it — did you see he hasn't read it? Maybe his phone died." "Maybe."

One character can't stop talking. The other answers in one word. And the reader immediately feels the difference — not because the author wrote "he was nervous," but because the rhythm of the lines itself tells them that.

That's where voice actually lives: not in the words, but in how many there are and when they appear.

How do I make voices sound different?

Decide for each character: what word would they never use, and what word do they always use? What's the first question they ask in an unfamiliar situation? Two "settings" like that are enough to start pulling the voices apart.

How much "said" is too much?

There's no hard rule — just feel. If "said" isn't pulling your attention, it's invisible. If you stumble on it while reading aloud — swap it for a beat or drop the tag entirely. A rough guide: one tag per 3–5 lines in fast dialogue, more often in slower scenes.
