About this demo

Gemini provides the teaching conversation, Spatius animates the avatar with live lip sync, and a second model turns the teacher’s speech into HTML blackboard notes and diagrams. All three student turns use prerecorded speech through the microphone input path and are audible in the recording. A spoken follow-up asks for the complete worked correction. This page plays the recorded session.
