NadouPro Performance Tags Guide

TIP

Performance tags are a Nadou TTS feature, optimized for film and TV dubbing. They combine line meaning and context to control a character’s emotion, tone, rhythm, and performance, so the voice sounds like a character acting in the scene instead of a flat narrator.

What Are Performance Tags

A performance tag is a voice-over control instruction. Add it to a line to guide the character’s emotion, tone, pace, or performance style, so the generated voice fits the scene.

For example:

[Angry]Why are you only telling me this now?
[Whisper]Keep your voice down. Don’t let them hear.
I'm fine[Pause]really, I'm fine.

Tags only control performance. They are not read aloud as part of the line.

Which Tags Are Supported

Native Performance Tags

Native tags are tuned for more stable results. Prefer them first.

Emotion

[Warm] [Affectionate] [Playful] [Amused] [Angry] [Furious] [Excited] [Hyper] [Awe] [Bitter] [Confused] [Thoughtful] [Content] [Determined] [Disgusted] [Happy] [Glad] [Thrilled] [Afraid] [Fearful] [Helpless] [Longing] [Proud] [Relieved] [At Ease] [Hurt] [Sad] [Ashamed] [Surprised] [Delighted]

Performance Style

[Singing] [Shout] [Yell] [Whisper] [Aside]

Pace and Expression

[Very Slow] [Slow] [Fast] [Very Fast] [Highly Expressive] [Low Expression]

Action and Sound

[Cough] [Laugh] [Laugh Out Loud] [Cry] [Scream] [Burp] [Sigh] [Sniffle] [Sneeze]

Pause

[Pause] [Long Pause]

Tags commonly used in dramatic performance:

[Happy] [Angry] [Sad] [Afraid] [Surprised] [Excited] [Confused] [Whisper] [Shout] [Laugh] [Cry] [Sigh]

Natural-Language Tags

Besides native tags, NadouPro also accepts any natural-language description of the performance, for example:

[Exhausted but pretending to be calm]I'm fine. You go first.
[Lower your voice, tense]They seem to have caught up.
[Calm on the surface, furious inside]That's your explanation?

Natural-language tags are better for nuanced, mixed states, but they may be less stable than native tags. Prefer a close native tag first, and use a natural-language tag only when no native tag is enough.

How to Use Enhance Performance

Enhance Performance can read emotion, tone, and rhythm in dialogue and add suitable performance tags automatically. It is currently available in the storyboard and in generation tools.

In the Storyboard

In storyboard dialogue, select a continuous conversation, then use Enhance Performance.

The system uses surrounding context to judge each line’s emotion and performance, then adds suitable tags. The more complete the conversation, the easier it is to catch emotion shifts and plot turns.

Use it for:

• Continuous dialogue between multiple characters
• Scenes where emotion changes step by step
• Beats with conflict, reversal, or rising emotion
• Lines that need surrounding context to judge performance

Choose a semantically continuous, complete stretch of dialogue.

In Generation Tools

Enter a stretch of plain dialogue in the generation tool prompt box, then use Enhance Performance. The system uses the full context to choose emotion, tone, and rhythm.

For example, input:

You finally came. I thought you would never show up again. For three years I called you so many times, and I asked everyone who knew you, but no one knew where you had gone. Now you suddenly come back and all you say is “long time no see.” Do you know how long I waited for those words?

After Enhance Performance:

[Bitter]You finally came. I thought you would never show up again. For three years I called you so many times, and I asked everyone who knew you, but no one knew where you had gone.[Pause]Now you suddenly come back and all you say is “long time no see.”[Sigh]Do you know how long I waited for those words?

You do not need extra character setup, plot background, or performance notes. Paste the plain lines. Results can vary with the text; adjust them to the scene before generating.

Tag Rules

• Put emotion, performance-style, pace, and expression tags at the start of a line. Use only one per segment; do not stack them.
• Action and sound tags can be inserted at the matching place in the line.
• Pause tags go between the two phrases that need a break.
• Do not over-tag. Mark only the moments that clearly change the scene or performance.
• For a very slow pace, [Long Pause] between phrases usually sounds more natural than using [Very Slow] alone.
