Voice AI Chatbot with Graph RAG Experts

Tools that fit

Watch out for

• ⚠ Voice latency can degrade user experience so optimize the pipeline by processing text synthesis in parallel where possible or using streaming endpoints.
• ⚠ Graph RAG results may be too verbose for speech so add a summarization step to keep responses concise and natural sounding.
• ⚠ ElevenLabs API keys must be secured in n8n credentials rather than hardcoded to prevent unauthorized access to your voice services.
• ⚠ InfraNodus graph structures vary by expert so implement fallback logic to handle queries that do not match any specific domain graph.
