A prompt for a Voice AI Agent in n8n clearly defines the agent’s persona, objectives, style, and the information it needs to collect or respond to during voice interactions. An effective prompt should include a greeting, the agent's identity and function, background context, conversation flow, style guidelines (such as friendly and natural tone), sample questions, and a closing statement. Integration with ElevenLabs, OpenAI, or Voiceflow allows the agent to process and understand spoken user input, retrieve relevant details via RAG or knowledge graphs, and provide context-aware responses—all orchestrated through n8n workflows. Use this structured prompt format to guide the agent’s voice outputs, automate follow-ups, and deliver seamless customer or task-focused voice assistance.
