Characters, Voice, and Dialogue

Making a character who is still the same person in episode seventy

Overview

Short drama viewers rarely remember plot. What they remember is people: who was humiliated, who betrayed whom, who finally won. That is why an inconsistent character damages a series far more than an ordinary plot does.

This course covers consistency from two sides that are usually treated separately although they depend on each other: consistency of appearance, the face that must hold across hundreds of images, and consistency of voice, the way a character speaks and chooses words so they stay recognisable.

One section deals with register and forms of address, which decide instantly whether a character sounds real. Getting it wrong sinks a line from its first word; changing it without cause makes the viewer feel the character was swapped.

Learning Objectives

After this course you can:

  • Build a character sheet that works as the single source of truth across a series
  • Keep a character's face stable across hundreds of images
  • Give each character a voice recognisable without their name attached
  • Pick a register that matches a character's background, then hold it consistent
  • Choose an AI voice with a test that will not leave you regretful by episode fifty

Built by Microdrama AI

Built by the Microdrama AI team from the practices used to keep characters consistent across long series on this platform.

Who this course is for

For creators who have produced episodes and found their characters drifting in appearance or in behaviour. Making Short Drama with AI is best finished first.

What you'll need

  • One series in progress with at least two main characters
  • Image and voice generation tools

You'll leave with

  • Character sheets for two leads, both halves filled in
  • One scene rewritten in five different voices
  • Voice test results for two characters, including the conversation test
  • A completion certificate, if you enroll

Course material

This course material is open to everyone. Enrolling only saves your progress.

1The character sheet as single source of truth

A character sheet is one page per person holding everything that must not change. Its purpose is not to be read by the audience but to be the only place you check when you are unsure at episode forty.

Appearance halfCharacter half
Age and face shapeWhat they want
HairWhat they fear
Clothing colour and cut per actHow they speak when angry
The identifying detail always presentOne thing they would never do

Fill the sheet before writing episode one, not after. A sheet assembled later only records what already happened; a sheet written up front can stop your character drifting for no reason.

2Keeping the face the same

Image models remember nothing between requests. Every image is made from scratch, so resemblance has to be forced through a reference rather than hoped for.

  1. 1Lock one reference image per character at the start of the series.
  2. 2Take the reference from a neutral angle: face front or slightly turned, even lighting, no extreme expression.
  3. 3Include that reference in every image request, without exception.
  4. 4Keep the references in one place along with the settings, so no stray version can creep in.

An extreme reference tilts everything derived from it. If your reference was captured mid-grin, every sad image will look wrong, and you will blame the model when the problem is the reference.

What breaks resemblanceHow often it is the culpritWhat to do
An angle far from the referenceMost oftenSwap the shot. Losing one angle is cheaper than losing the likeness
Very different lightingOftenLock one lighting mood per location
A small face in the frameOftenMove up to chest up
Switching models midwayRare but fatalFinish a series on the model you started with

3Voice: how each character picks words

Voice is not the physical sound. Voice is how a specific person chooses words. Two characters can deliver identical content and still sound like two different people.

CharacterSaying the same thing
Executive"I want that report on my desk before five."
Enforcer"Sort it this afternoon. Do not make me come back."
Teacher"If it is not finished, we will work it out together."
Mother-in-law"I will wait until this evening. I do not like waiting twice."

Five things that build a voice

  • Education: a doctor reaches for different words than a car park attendant
  • Age: a teenager does not speak like a retiree
  • Region: one or two markers are plenty; overdoing it produces caricature
  • Status: an executive, a courier, and a guard each hold a different distance from whoever they address
  • Personality: quiet, blunt, sarcastic, conciliatory

4Register and forms of address

This decision is rarely discussed and decides a great deal. Get it wrong and a character sounds false from the first word. Change it without cause and the viewer feels the character has been swapped.

RegisterFitsAvoid when
Plain and direct, contractions, first namesClose relationships, family, romanceA formal meeting or a rigid chain of command
Slang and clipped grammarYouth, close friends, a specific cityCharacters from elsewhere, or formal scenes
Full sentences, titles, no contractionsBoardrooms, clients, doctors, lawyersConversations between friends or family
Deferential address plus formal grammarRespect with visible distanceTwo people who are already close
Polite but warm, honorifics with first namesEveryday courtesy between near-equalsRelationships that demand formal distance

Consistency matters more than the choice

A character who is slangy in episode two, formal in episode ten, and neutral in episode twenty with no cause reads as three different people. If the register does change, the change must have a visible reason: a promotion, a move, a relationship that shifted.

A REGISTER CHANGE WITH A CAUSE

Episode 3. Maya is still on a temporary contract, speaking to Dian.

MAYA

I sent the report through, sir.

Episode 46. Maya now owns the company. Dian stands at her desk.

MAYA

Your report is two days late.

Nobody needs to explain the shift from deference to directness. The viewer feels the power move immediately.

5The five jobs of dialogue

New writers often think dialogue means people talking. In short drama, dialogue is the story engine. If a line is not doing one of these five jobs, it can almost certainly be cut.

JobExample
Move the conflict"I am calling off the wedding."
Deliver information"The will has been found."
Show character"Money buys everything."
Raise emotion"You are not fit to say my mother's name."
Close the episode"The owner of this company is you."

One line, one job

Dialogue here has to work fast, but fast does not mean dense. A line stuffed with explanation sounds false and actually slows things down, because the viewer has to unpack it first.

Three jobs crammed inOne line, one job
"I want to explain that none of this is my fault and there is a lot you still do not know.""I did not steal it." then "Pull the CCTV."

6Choosing an AI voice

The lead's voice will be heard for hours. Choosing it after one short line is the most common way to regret it later.

  1. 1Test each candidate on three lines of different weight: one neutral, one angry, one quiet.
  2. 2Use exactly the same lines for every candidate. Comparing voices on different lines compares nothing.
  3. 3Test voice pairs inside one conversation, not separately.
  4. 4Listen to that conversation with your eyes closed. If you can still tell them apart, the choice is good enough.
  5. 5Record the settings on the character sheet, including the model name.

Many voices sound good neutral and fall apart when they have to be angry. Since anger happens constantly in this format, the angry line should be the main exam rather than an afterthought.

Wrong vs Right

Wrong

"I feel very sad today."

Right

"If your mother were alive, she would be ashamed of you."

Why. Naming a feeling instructs the viewer to feel. Naming a consequence makes them feel it themselves, and delivers new information about the relationship at the same time.

Wrong

"He is very rich."

Right

"He just bought this building."

Why. A trait is abstract, an act is concrete. A line of the same length now carries an image the viewer can picture.

Wrong

"You are lying."

Right

"You said father was dead. So who is the man outside?"

Why. An empty accusation is refuted in one word. An accusation carrying evidence forces the other person to move, and that is what drives a scene.

Wrong

Every character speaks in the same register, in the boardroom and to the security guard alike.

Right

Register is chosen per relationship: deferential upward, plain with a partner, formal in meetings.

Why. Register is the fastest signal of a relationship an audience picks up. Flattening it throws away free information.

Wrong

Choosing the lead's voice after one calm introductory line.

Right

Choosing it after hearing an angry line and a quiet line from the same candidate.

Why. Most voices sound fine when calm. What separates them is how they hold up going up, and in this format they will go up constantly.

Exercises

1One scene, five voices

  • Write one short scene, about eight lines of dialogue.
  • Rewrite the same scene for five different characters: an executive, a delivery rider, a teacher, a mother-in-law, a student.
  • The content must stay identical. Only word choice and register change.

Output. Five versions of the same scene, side by side.

2Character sheets for two leads

  • Write character sheets for two leads, both halves filled in.
  • Do not skip the line about what they would never do.
  • Decide the register each uses toward three different people.

Output. Two one page sheets plus a register table per relationship.

3A complete voice test

  • For both leads, test at least three candidate voices on three lines of different weight.
  • Then run the conversation test: one short scene bringing the two together.
  • Listen with your eyes closed and note whether you can still tell them apart.

Output. A results table plus the settings for the chosen voices.

How to Assess Yourself

You are ready to move on when all of these hold:

  • Character names can be stripped from your dialogue and a reader can still tell who says what
  • Your character sheet includes one thing that character would never do
  • Each character's register is consistent, and every change has a visible cause
  • No line of dialogue narrates something already visible on screen
  • You can name the job of every line; if you cannot, that line does not need to exist

Summary

  1. 1Viewers remember characters rather than plot, so an inconsistent character does more damage than an ordinary plot.
  2. 2A face only stays stable when a reference is attached to every image request, never when it is merely hoped for.
  3. 3Voice is word choice, and it is built from education, age, region, status, and personality.
  4. 4Register is the fastest relationship signal an audience reads; choose it deliberately and then hold it.
  5. 5Every line must do one of five jobs, and one line should carry one job rather than three.

Frequently Asked Questions

What if the face keeps drifting even with a reference?

Check three things first: camera angle, lighting, and how much of the frame the face occupies. Those cause it more often than the model does. If a shot demands one of them deviate far, replacing the shot is usually cheaper than forcing it.

How many characters are reasonable for one series?

Two leads, one antagonist, and three to five supporting characters are enough for 60 to 100 episodes. Every added character adds consistency cost to every episode after it.

Can I use regional speech in dialogue?

Yes, and it often strengthens a character. The key is restraint: one or two markers per character already conveys origin. Overdoing it produces caricature and makes the voice engine harder to work with.
