Read a page of stiff dialogue out loud and you will hear the problem instantly. Nobody talks in complete, grammatical paragraphs. Real people interrupt each other, trail off, answer a different question than the one they were asked, and say yeah when they mean no. Fiction dialogue that ignores this sounds like a press release with quotation marks around it.

The first thing to understand is that dialogue in fiction is not a transcript. A real transcript is full of ums, false starts, and boring logistics. Good dialogue is a cleaned-up version of reality: it keeps the rhythm and messiness of speech while cutting the parts nobody needs. The goal is the feeling of real talk, not a recording of it.

People rarely say exactly what they mean. A character who says fine is usually not fine. A character who changes the subject is telling you what they are avoiding. This gap between words and meaning, called subtext, is what makes dialogue interesting. If every character says precisely what they think, the conversation has nowhere to go.

Keep attribution simple. Said is invisible to readers, which is exactly what you want. Replacing it with hissed, exclaimed, or interjected on every line draws attention to the machinery. Save the unusual verbs for moments that genuinely need them, and let the words themselves carry the emotion.

Action beats do more work than tags. She folded the letter twice before answering tells the reader more than she said nervously. A beat also controls pacing: a short beat speeds a scene up, a long one slows it down. Use beats to show who has power in the scene, who is avoiding eye contact, and who is waiting for the other person to finish.

Write a scene of two people arguing about something small, like who forgot to lock the door, while the real argument is about something much bigger. Let neither character name the real issue. When you read it back, the tension should be obvious even though the words are ordinary. That is subtext doing its job.

Finally, read every dialogue scene out loud before you call it done. Your ear catches what your eye forgives: sentences no human mouth would produce, three characters who all sound like you, and exchanges that go on two lines past their natural end. Cut the last two lines of most exchanges and the scene usually gets sharper.

Dialogue fails most often when every character sounds like the author. Fix it by giving each major character a verbal fingerprint: one favours short sentences, another rambles; one swears, another apologises; one answers questions with questions. You do not need a dialect or a catchphrase. A few consistent habits are enough for a reader to tell who is speaking before they reach the tag.

Test your voices by stripping out every dialogue tag and action beat from a scene, then reading it cold. If you cannot tell who is talking, the voices are not distinct enough. Another useful trick is to write a scene where two characters disagree about something small, like what to have for dinner, and let their speech patterns carry the whole exchange. When the voices are right, the scene works even though nothing much happens. When they are wrong, no amount of plot will save it. And remember that silence is dialogue too: a character who says nothing at the exact moment everyone expects them to speak has just said more than a paragraph of explanation ever could.

Reading dialogue aloud is the fastest test. If a line feels awkward in your mouth, it will feel awkward in a reader's head, so say each scene out loud before calling it finished. A recording helps too: hearing your voice stumble exposes stiffness silent reading hides. Actors do table reads for this reason, and writers can borrow the trick.
