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
Core Components
Orchestrator
Conversational Agent Orchestrator
Coordinates the full lifecycle of each interaction—routing conversations, managing multi-step tasks, and dynamically adapting based on user input. Ensures digital humans respond contextually and escalate when needed with precision and empathy
Prompt Router
Intelligent Prompt Engineering Engine
Generates structured prompts and manages LLM interactions behind the scenes. It tailors the flow of each customer dialogue by aligning it with business objectives, improving both accuracy and response quality in real time
Monitoring
AI Performance & Behavior Tracking
Monitors every interaction for quality, latency, tone, and task completion. Provides feedback loops for model improvement and trust scoring—ensuring digital humans remain aligned with compliance and customer experience goals.
Continuously evaluates digital human interactions for responsiveness, tone, and effectiveness
Knowledge
AI-Powered Knowledge Engine
Connects digital humans to structured knowledge bases and vector databases. Enables contextual search, retrieval-augmented generation (RAG), and personalized support using FAQs, help articles, and real-time organizational data
API Development
Secure API Gateway & Control Layer
Enables safe, scalable connectivity between digital humans and backend systems like CRM, ticketing, or inventory. Handles authentication, throttling, rate limits, and data governance to protect sensitive information and ensure continuity of service
