AI x Voice x Live2D Integration in Web Applications

Recently, our company has been engaged in numerous discussions about the ideal interface for AI systems. We believe that the interface is just as crucial as the AI technology itself, varying based on the product and its users.

Through our experimentation with various avatar interfaces including 3D and 2D options, we've found Live2D to be particularly compatible with AI and web services - user-friendly, easy to implement, and highly effective.

Live2D is a platform that creates rich, 3D-like expressions by rigging multi-layered 2D illustrations, a process where deformation points are strategically placed across the artwork to enable realistic movement and animation.

We began experimenting with integrating Live2D as an AI interface in web applications. Live2D provides the Live2D Cubism SDK for Web, which allows for seamless web implementation. Using the Live2D Editor, everything from simple sketches to detailed illustrations can be transformed into interactive characters (Live2D models).

Our team modified the SDK to work with the Vue.js platform. Additionally, we enhanced the lip-sync functionality to work more seamlessly with various Text-to-Speech (TTS) platforms, enabling the mouth to synchronize with speech even in audio formats beyond WAV.

Please check out our demonstration video:

While we cannot share the code for this demo as it's largely based on the Live2D Cubism SDK for Web, we've developed an optimal solution for integrating Live2D with Vue.js, a popular web application framework.

The demo uses the standard animated character included with Live2D Cubism SDK for Web, but Live2D's expressive capabilities extend far beyond this. It can create nearly 3D-model-like movement with more sophisticated illustrations, or bring charming, soft cartoon-like characters to life with surprisingly rich expressiveness.

At Goldrush Computing, we're committed to creating new user experiences by combining intelligent AI conversations, advanced natural voice synthesis engines, and Live2D. If you're interested in designing AI user experiences that consider both AI logic/data and interface elements from the ground up, please feel free to contact us.

Addressing Common Concerns

1. "Is implementation expensive?"

Live2D is a cost-effective alternative to full 3D modeling. Review the Live2D License Agreement for details.

2. "Can it work across different industries?"

From casual characters to formal assistants, Live2D can be adapted to match your brand's tone.

3. "How do we start integrating this?"

We recommend considering AI, TTS (voice), and Live2D together from the early phases of product design.

Disclaimer

We recommend envisioning AI, TTS (voice), and Live2D as a unified whole from the early phases of product design, with cross-functional teams collaborating on the complete experience rather than working in isolation on AI logic, voice synthesis, or Live2D animation design separately.
