Party Line @ DEF CON 33

Details needed to power ElevenLabs Conversational AI for the Call Center Village party telephone line at DEF CON 33.

Disclaimer

AI was used in the creation of this software.

Overview

We're using the Twilio integration within ElevenLabs to tie an agent to a phone number. A custom ElevenLab's agent will answer the call and assist the caller based on the System Prompt and/or Agent knowledge base.

This document is meant to explain all the configuration used to reproduce the agent. You can also use it as a baseline for creating your own.

Build Complete Agent Package

Run the build command to generate all files:

php bin/console app:build-agent

This will:

1. Generate agent/Keywords.txt from all markdown files in the kb/ folder
2. Generate agent/pronunciation-dictionary.xml from all markdown files in the kb/ folder
3. Compile all agent config files and kb files into dist/SystemPrompt.txt
4. Copy all necessary files to the dist/ folder

Individual Commands

You can also run commands individually:

# Generate keywords from kb folder
php bin/console app:generate-keywords

# Generate pronunciation dictionary from kb folder
php bin/console app:generate-pronunciation-dictionary

# Compile system prompt only
php bin/console app:compile-agent

Output Files

All generated files will be in the dist/ folder:

• SystemPrompt.txt - Complete system prompt for ElevenLabs
• Keywords.txt - Extracted keywords from knowledge base
• Opener.txt - Agent opener message
• pronunciation-dictionary.xml - Pronunciation guide for ElevenLabs
