Building AI Avatars for Speaking Practice

A deep dive into building a real-time AI avatars for language speaking practice. We’ll explore how realtime AI agents orchestrate multiple LLMs, Voice, and Video sources to power dynamic conversations, and maintain low-latency interactions. Beyond conversation, the system performs automated speaking assessment (pronunciation, grammar, and vocabulary). We’ll cover architectural decisions, streaming pipelines, evaluation loops, and the challenges of creating responsive, human-like interactions.
