New Feature Automated Lip-Sync and Emotional Expression for Avatar Characters

 Introducing Automated Lip-Sync and Emotional Expression

We've supercharged ChromaToons with a sophisticated new feature that automatically brings your characters to life: Automated Lip-Sync and Emotional Expression. 

Now, your characters won't just move—they'll talk and feel!

1. AI-Driven Lip-Sync

Say goodbye to frame-by-frame mouth-shaping! The new feature automatically analyzes the audio timeline you provide and generates accurate lip movements for your character.

• Timeline Integration: The character's mouth shapes change precisely according to the sound words (phonemes) in your uploaded audio. This creates smooth, professional-quality dialogue with minimal effort.

• Custom Mouth Textures: Want a unique look? ChromaToons allows you to upload and edit your own custom mouth texture! You can design unique mouth shapes that perfectly match your character's style.

2. Full Emotional Control

Beyond dialogue, you can now define and transition between a range of core emotional states for your character, making your animations truly engaging:

• Emotional States: Easily switch your character's expression to reflect Sad, Happy, Normal, or Angry emotions.

• Comprehensive Expression Design: To facilitate both lip-sync and emotional changes, we provide a structured guide. You'll organize all necessary mouth sprites within a single 1024x1024 px PNG image texture. This texture acts as a single source for all expressions and dialogue movements.

3. The Lip-Sync Chart: Your Guide to Customization

To make customization simple and precise, a detailed Lip-Sync Chart is provided. This chart is your essential guide for arranging all the mouth sprites on your single texture image:

Function	Description
Phoneme Placement	Maps specific mouth sprites (e.g., A, E/L,  O/U, closed lip) to their exact positions on the texture.
Emotional Overlays	Guides you on how to arrange the different emotional mouth sets (e.g., the Sad mouth sprites, the Angry mouth sprites) within the texture.
Seamless Integration	Ensures that when the app switches between a Happy expression and the talking state, the transitions are smooth and the correct mouth shape is always displayed.
