AI Voice Chat Agent Integrating InfraNodus and ElevenLabs

This n8n workflow creates an advanced AI voice chat system that connects users with expert knowledge graphs via InfraNodus, combined with voice interaction through ElevenLabs. The workflow is initiated by a webhook trigger when a user sends a message through an ElevenLabs conversational agent. The core component is the AI agent, which evaluates the user’s query and dynamically chooses relevant ‘expert’ tools—such as InfraNodus graphs or scholarly books—to generate contextual responses. These tools include specialized knowledge sources like the Waves into Patterns, Manual Book, Polysingularity Letters, and others, each accessed via HTTP requests to InfraNodus API. The AI agent synthesizes replies based on the selected experts’ insights and maintains conversation context with a memory buffer, ensuring coherent multi-turn interactions. Finally, the response is sent back via the webhook, enabling voice or text-based user engagement. This workflow is ideal for creating intelligent voice assistants, research support systems, or conversational agents that leverage complex knowledge graphs and AI insights.
