The highly anticipated addition of custom variables in Voice AI prompts has arrived! This new feature enables you to enhance Voice AI interactions by seamlessly incorporating contact-specific details, creating more personalized and engaging conversations.


Key Benefits of Custom Variable Support

Using custom variables in Voice AI prompts enhances the conversation flow and provides several advantages:

How to Add Custom Variables to Prompts

Adding custom variables to your Voice AI prompt is simple. Follow these steps:

  1. Go to Agent Goals – Navigate to the Voice AI settings in your platform.
  2. Select Advanced Goals – Within the Agent Goals section, access the Advanced Goals settings.
  3. Choose Custom Variables – Select the variables you want to add from the available tag list.
  4. Manually Insert Variables – Use the format {{contact.name}} to insert a specific contact's name, or use other predefined variables as needed.

Best Practices for Using Custom Variables

To maximize the effectiveness of custom variables, follow these best practices:

  • Use Variables Thoughtfully – Ensure the variables you use add value to the conversation and improve clarity.
  • Test Before Deployment – Verify that the custom variables populate correctly in test calls before going live.
