• Multi-Model Orchestrators - Provides a unified interface to route text through various voice synthesis engines for realistic spoken audio.
• Virtual Camera Drivers - Sends the generated avatar video stream to a virtual camera device for use in broadcasting software.
• Multi-Avatar Rendering - Renders multiple digital humans in one frame with assigned voices and speech tasks for each.
• Unlimited-Duration Talking Video Generators - Limit memory usage through a caching system to support virtually unlimited video length during live streaming.
• Inference Session Isolation - Manages concurrent user connections by isolating individual avatar rendering pipelines using unique session identifiers.
• Frame Memory Buffers - Uses a sliding-window memory buffer for video frames to prevent disk read bottlenecks during long-duration streaming.
• Avatar Appearance Configurators - Integrates user-defined images or models to change the visual identity of the digital human.
• Idle Animation Triggers - Plays predefined looping videos or movements when the avatar is not speaking to maintain natural presence.
