When Dialogue Doesn’t Work, Where the Problem Usually Lies

Dialogue is the easiest part to write, and also the hardest part to write well. It is easy because everyone knows how to talk; it is hard because making it sound like "something a person would say" rather than "lines in a script" requires a special kind of sensitivity. Audiences are extremely quick to notice this—once the dialogue feels wrong, even the best visuals will immediately pull them out of the story. This article lays out four of the most common dialogue problems. They show up in different ways, but they share the same root cause: forgetting that dialogue is meant to be heard by people.

1. Problem One: Too Much Information

This is the most common issue. A character opens their mouth and delivers a long explanation: "This project began last March, took fourteen months, involved twenty-seven people across three departments, has now completed its first phase, and will move into testing next." The problem is not that the content is wrong, but that no one talks like this. In real communication, information is fragmented, omitted, and dependent on shared context. Explaining all the background at once serves the writer’s needs, not the character’s. The test is simple: read the line out loud and ask yourself, "Who would say this to a friend in real life?" If the answer is no one, it needs to be broken down. There are usually two ways to handle it:

• First, split it up. Break one explanatory passage into several conversations in different situations, revealing only part of the information each time.
• Second, turn it into visuals. Some information does not need to be spoken—the scale of a project can be shown directly, and relationships between characters can be suggested through behavior. This is also the advantage of film and television over text: what can be acted does not have to be said.

2. Problem Two: No Subtext

The second type of problem is dialogue that is too "direct"—characters say exactly what they want to say, leaving no space. "I’m angry right now because you didn’t help me earlier." "I’ve actually always felt inferior; I just pretend not to care." The problem with this kind of dialogue is that it explains both emotion and motivation completely, leaving the audience no room to participate. In real interpersonal communication, people rarely express their true thoughts directly. There is always a gap between what someone wants to say and what they actually say—that gap is subtext. Good dialogue often creates a mismatch between "what is said" and "what is really meant": (The table is a mess. He slowly sets the cup upright.) "It’s fine. I’m used to it anyway." On the surface, the line says "it’s fine," but the audience can read the opposite meaning. That process of "reading it" is the audience’s participation—and the feeling produced by participation is much stronger than being told directly.

3. Problem Three: Everyone Sounds the Same

The third type of problem is less obvious, but just as fatal: everyone in the story speaks with roughly the same rhythm, vocabulary, and tone. This makes the characters lose their distinctiveness. If the audience closes their eyes and cannot tell who is speaking, it means the characters have not been "built". A person’s way of speaking is shaped by many factors: age, region, education, profession, personality, and current state. These differences should appear in the dialogue:

• Some people speak in short bursts; others like to talk around a point.
• Some people prefer concrete examples; others tend to speak in abstract principles.
• Some people go silent when interrupted; others immediately fight back.

A practical way to achieve this is to write a set of "language habits" for each major character: sentence length, commonly used words, topics they avoid, and how they behave when nervous. Then check the dialogue against it after writing.

4. Problem Four: Stating Emotions Directly

The fourth type of problem is related to the second, but more specific: letting characters directly announce their emotions. "I’m scared right now." "I’m so happy." "I’m disappointed in you." This kind of dialogue is ineffective because emotion is something the audience should feel, not something they should be told. If a character directly says "I’m scared," the audience is actually less likely to feel fear—because they have been deprived of the chance to judge for themselves, leaving only the information "Oh, he’s scared." The replacement is to express emotion through behavior and detail: trembling hands, repeatedly looking at the door, saying something unrelated. The conclusion the audience reaches on their own is the one that truly works.

5. How Dialogue and Visuals Work Together

The shared solution to the four problems above can actually be summed up in one sentence: don’t say what can be acted. Dialogue and visuals complement each other. What visuals can convey—position, action, environment, state—does not need to be repeated in dialogue; the strength of dialogue lies in conveying what visuals struggle to express, such as information, viewpoints, intentions, and things outside the frame. One way to judge this: after writing a passage of dialogue, cover up the visual portion and look only at the lines. If they are smooth, complete, and contain all the information, the dialogue is carrying too much—it needs to give some of that work back to the visuals. Conversely, if the visuals make no sense at all after the dialogue is covered, then not enough information has been provided, or omissions have been used where they should not be.

6. Coordination During Production

After the dialogue is written, it still has to be executed. Voiceover is a second creation. The same line can mean something completely different when read with different speed, pauses, and emphasis.

• In NadouPro, dialogue voiceover is generated through text-to-speech. The input includes the lines, voice, and performance settings—"how it is read" is just as important as "what is read," because subtext is often hidden in the handling of tone. The voice should match the character. Giving an adult character a teenage voice will immediately pull the audience out of the story. Choosing a voice belongs to the logic of casting, not to technical parameters. If an existing recording needs to be adjusted, voice conversion can produce a voice-changed result based on the original human voice audio and the target voice. Dialogue should correspond to the shot. Which shot a line lands on, what shot size it is paired with, and where the character is positioned in the frame will all affect how the dialogue is perceived.
• In NadouPro, storyboard nodes handle video storyboard processing and include information such as shot size, movement, and camera angle—the correspondence between dialogue and shots should be placed at the storyboard level, rather than decided temporarily during voiceover.

7. A Self-Check List

1. Does it sound like something a person would say when read aloud? Would anyone speak this way in real life?
2. Is there information overload? Can it be split into several conversations, or handed over to the visuals?
3. Is there subtext? Are what is said and what is meant exactly the same?
4. Are the characters’ ways of speaking distinct? Can you tell who is speaking with your eyes closed?
5. Is the emotion being "said" or "acted"? Is the feeling being announced directly?
6. If you cover the visuals and read only the dialogue, does it seem suspiciously complete? That means the dialogue is carrying too much.

Finally

The root of dialogue problems is often that the writer is standing in the position of the "narrator" rather than the "character". The narrator needs to make things clear; the character only needs to express what they want to express. The difference between the two is the difference between "script dialogue" and "real conversation". So the most effective action when revising dialogue is to read every line out loud. The parts that feel awkward when spoken are usually where the problems are. And although audiences may not analyze exactly what is wrong with the dialogue, they can immediately feel that "this line is off"—which is why dialogue is worth revising again and again.
