Vtkool Launches Real-Time Voice Dialogue with GPT-Live-1 Support on September 30
GeeXai has launched GPT-Live-1 support for Vtkool, its AI character dialogue platform, starting September 30, 2026. The update enables real-time voice interactions with interruptions, backchannels, rephrasing, and character-specific speaking styles. Combined with Live2D/VRM avatar expressions, lip sync, RAG, and external tools, it positions AI characters for web customer service, education, and interviews as conversational partners rather than simple Q&A agents.

Backchannels and interruptions can make a web avatar feel much less like a form. I want to see how Vtkool performs the waiting moments while RAG or tools prepare an answer.
