Architecture Overview
User Interaction Layer
This layer powers the conversation between users and digital humans. It manages multimodal interfaces—voice, video, or chat—allowing customers to interact naturally across platforms. With personalization built-in, it adapts to customer tone, language, and preferences to deliver human-like support in real time
Application Logic Layer
This is the brain behind the digital human's behavior. It governs workflows like customer queries, ticketing, troubleshooting, or appointment scheduling. It ensures that each interaction follows business rules and service logic while maintaining context across channels and sessions
Agent Orchestration Layer
The orchestration layer coordinates different digital human capabilities—like handoff to a live agent, escalation logic, and task delegation. It manages multi-turn conversations and syncs actions between various backend systems, ensuring a seamless and intelligent service experience
AI/ML Models Layer
This layer empowers digital humans with cognitive capabilities. From intent recognition and emotion detection to adaptive learning, this layer uses trained AI models to understand, reason, and respond accurately. It continuously evolves using interaction data to improve support quality
Data & Knowledge Layer
This foundation gives digital humans access to everything they need to assist—FAQs, product info, CRM data, and knowledge bases. It ensures instant, context-aware responses and enables the system to retrieve, learn, and reference the most relevant content for customer service delivery
