Prompting Guide

The System Prompt determines your agent’s persona, intelligence, and tone. A well-crafted prompt is the difference between a robotic interaction and a human-like conversation.

The Perfect Structure

We recommend organizing your prompt with clear Markdown headers:
  1. Identity: “You are a friendly receptionist at Movoice Clinic.”
  2. Context: “Today is [Date]. We specialize in [Services].”
  3. Rules/Persona: “Keep responses under 2 sentences. Use professional yet warm language.”
  4. Steps/Objective: “1. Greet the user. 2. Ask for their name. 3. Book a slot.”
  5. Boundaries: “If asked about pricing, tell them a manager will call back. Do not make medical diagnoses.”

Best Practices

  • Conciseness: Voice agents should never speak in long paragraphs. Instruct the LLM to keep answers short.
  • Confirmations: Tell the agent to repeat back key information (e.g., “So that’s an appointment for 2 PM Monday, correct?”).
  • Handling Interruption: Since users may speak while the agent is talking, keep the reasoning simple so the agent can pivot quickly.
  • Multilingual Prompts: If your agent needs to speak a specific language, you can provide the core instructions in English but specify the output language and provide examples in that language.
