Your AI Dialogue Sounds Robotic. Here's the Fix.

You prompted a witty conversation and got a mumbled mess. The problem isn't your script; it's how you're giving the AI its stage directions.

The "Audio Hallucination" Problem

You've written the perfect scene. Two characters, a hero and a villain, exchanging tense words. You feed the script into the AI. The result? The hero's lips move while the villain's voice comes out. Or both characters mumble at the same time. Or worse, you get a narrator reading the lines over silent, moving mouths.

This is called an "audio hallucination." It happens when you give the AI a script but fail to give it one critical piece of information: **who is speaking.**

An AI model like Veo 3 doesn't understand conversational context. It only understands direct commands. Failing to assign dialogue to a specific speaker is like handing a script to two actors and telling them to "figure it out."

The Non-Negotiable Rule of AI Dialogue

Veo 3's power comes from its unified audio-visual generation. It learns the relationship between mouth shapes (visemes) and sounds (phonemes) as a single concept. To trigger this correctly, you must eliminate all ambiguity from your prompt.

From now on, every line of dialogue in your prompt must follow one simple, unbreakable format:

Character Name: "The line of dialogue goes here."

That's it. That's the entire secret. This isn't a suggestion; it's a command. This syntax explicitly "binds" the audio of the dialogue to the visual entity of the character. The colon is the critical piece of syntax that tells the model, "The following string of text should only be performed by this subject."

The Director's Workflow for Dialogue

Stop thinking like a novelist and start thinking like a screenwriter. Your prompt isn't prose; it's a script combined with a shot list.

When you're building a scene with dialogue, define your subjects first. Give them clear, simple names the AI can reference (e.g., "A grizzled space marine," which you can refer to as "Marine" in the dialogue).

This is why the **Character Card** system in the Prompt Master G is so effective. It forces you to separate your characters from their actions and, by extension, their dialogue. By building your prompt in this structured way, you make it impossible for the AI to misinterpret who is supposed to be speaking.

The Bottom Line

Don't just write a script. **Assign it.** Using the `Character: "Dialogue"` format is the single most effective technique for generating clean, synchronized, and believable dialogue in your AI videos.
