Welcome to the fundamentals of Lacy.ai. Here, we explore the essential building blocks that you need to understand before configuring your AI assistant and calls.

​
1. System Prompt & Initial Message

System Prompt
  • The “brain” of your AI assistant. You write a short (or long) set of instructions that guide the assistant’s behavior and tone of voice.
  • This includes any important business info, disclaimers, or how you want the AI to handle edge cases.
  • For example: “You are a helpful phone assistant for XYZ Company, you greet in a friendly manner, confirm the caller’s info, etc.”
Initial Message
  • The very first thing the AI says.
  • Typically short, like “Hello, thanks for calling XYZ Company!“

​
2. Voices

  • Lacy.ai integrates with ElevenLabs voices for natural-sounding speech.
  • You can clone your own voice by providing audio samples or pick from built-in voices.
  • Each voice can have adjustable parameters like speech speed, filler usage, or accent (if available).

​
3. Putting It All Together

  • An AI Assistant is built by combining a system prompt, an initial message, and a chosen voice.
  • Optionally, you add tools (like “transfer call” or “end call”).
  • Once the assistant is set, you assign it to a phone number (for inbound) or a campaign (for outbound).
