Create a Voice AI Chatbot with ElevenLabs and InfraNodus

Give your AI voice — and expertise.

This automation connects ElevenLabs’ lifelike conversational voice agent with InfraNodus GraphRAG-powered knowledge graphs to create an intelligent, speech-enabled assistant that draws from multiple expert knowledge bases — all without the complexity of vector stores.

Perfect for educators, product teams, researchers, or anyone who wants a domain-smart voice chatbot that speaks clearly and retrieves knowledge meaningfully.

What it does:

🎙 Receives voice input from ElevenLabs
🔄 Converts speech to text and sends the query to n8n
🧠 Uses AI Agent to select the most relevant InfraNodus knowledge graph (expert)
📚 GraphRAG retrieves high-context answers with structured understanding
🗣 Synthesizes and speaks the final answer back to the user via ElevenLabs
💬 Supports both voice and text workflows — embeddable on websites

Why it’s powerful:

⚡ Fast to set up — no vector store engineering needed
🧩 Modular expert graphs — more clarity, better control
📈 High-quality retrieval based on graph structure, not keywords
🌐 API-first and embeddable — perfect for sites, products, or support
♻️ Reusable in other n8n workflows
