# Filler Audio

> Learn how to use filler audio to create more natural conversations with your AI assistant

Filler audio adds natural conversation sounds (like "hmm" or "one moment") while your AI assistant processes responses. This creates a more human-like interaction by eliminating awkward silences.

## How It Works

When enabled, your AI assistant will:

* Use short audio fillers during processing time
* Maintain engagement while formulating responses
* Signal active listening to the caller

   * Keeps callers engaged
   * Reduces hang-ups
   * Creates natural dialogue rhythm

2. **Enhanced User Experience**
   * More human-like interaction
   * Less awkward waiting
   * Better caller retention
   * Increased trust

## Setup

1. Go to your AI assistant settings
2. Find the "Filler Audio" option
3. Toggle it on
4. Save your changes

## Best Practices
