How it works

Voice AI agents use large language models to understand caller intent and respond naturally. Each agent is configured with a system prompt that defines its personality, knowledge, and behavior rules. When a call comes in (or goes out), the agent:
  1. Listens to the caller and converts speech to text
  2. Processes the text through the AI model with your system prompt
  3. Generates a response and converts it back to speech
  4. Takes actions (booking appointments, updating contacts) as configured
