Voice AI Custom Variable Support in Prompt

Key Features

The feature enables dynamic insertion of contact-specific details into prompts. Users can reference customer information like names and phone numbers using formats such as {{contact.name}}.

Main Benefits

• Personalized conversations that feel more human-like
• Improved context awareness for the AI agent
• Enhanced customer experience through tailored interactions
• Simple integration using straightforward tagging

Implementation Steps

Users navigate to Agent Goals, access Advanced Goals settings, select desired variables from available tags, and manually insert them using the prescribed format before saving and deploying.

Best Practices

The article recommends using variables strategically, testing before deployment, keeping prompts natural (avoiding overload), and maintaining current customer data.

Limitations

Currently, only system-defined variables related to contact details are available, though future updates may expand custom variable options.

This feature works across all Voice AI agents configured with Advanced Goals and requires test calls to verify proper variable population.
