When a Voicebot processes a user request, such as executing a tool call or fetching data, users may experience brief periods of silence. This "dead air" can make interactions feel unresponsive and increase perceived wait time, leading to confusion or drop-offs.

Conversational Fillers address this by playing short, contextual audio messages while the bot processes requests in the background, keeping users informed and engaged throughout the interaction.

How Conversational Fillers Work

When a tool call is triggered during a voice interaction:

1. The Voicebot plays a filler message immediately while executing the tool in parallel.

2. Once the tool execution is complete, the final response is delivered.

Filler messages are short, natural-sounding phrases such as:

• "Let me check that for you."

• "Looking this up…"

• "Just a moment while I review this."

Handling Multiple Tool Calls

• If multiple tools are triggered sequentially, their associated fillers are played in order.

• If the final response is ready before all fillers have played:

  • The currently playing filler is completed.

  • Any remaining queued fillers are discarded.

  • The final response is delivered immediately.

Barge-In Behavior

Users can only barge in (interrupt) after the final response is received. Filler messages are non-interruptible to ensure a smooth, natural listening experience. Core bot functionality remains unaffected.

Steps to Enable Conversational Fillers

1. Open your AI Agent in Sprinklr.

2. Click Settings in the left pane of the AI Agent window.

3. On the Settings window, click Feature Suite.

4. Enable the Filler Message toggle.

5. Enter the prompt for the filler message to define the tone and style (for example, polite, friendly).

   

6. Click Save in the bottom-right corner.

Steps to Enable Fillers at the Tool Level

1. Open the Tool you want to configure within the AI Agent.

2. Under the Description field, enable the Filler Message toggle.

3. Click Save.

   

Enable fillers for external/API tools where processing delays are expected. For internal or system tools, you can leave fillers disabled to avoid unnecessary audio output.
