# How Agentic Hosts Work

> The technical architecture behind sub-second conversational AI hosts that conduct live presentations.

## Core Components
1. **Finite State Machine (FSM)**: Manages presentation phases (Intro, Slide Presentation, Q&A Interruption, Outro, Wrap-up).
2. **Real-Time Audio Bridge**: Uses WebRTC via LiveKit with Deepgram STT and low-latency TTS for sub-second vocal response.
3. **Knowledge Retrieval**: Hybrid semantic vector search across slides and uploaded documents with strict anti-hallucination guardrails.
4. **Visual Synchronization**: Bi-directional event bus coordinating slide progression, pointer highlights, and interactive CTAs.
