Configurable interstitial audio for Voice

Voice AI Agents can now play configurable audio cues while processing requests during phone calls, replacing silence with a subtle signal that the AI Agent is actively working.

What’s new

When your AI Agent needs extra time to process a request — such as retrieving information from external systems — callers previously heard silence after the initial acknowledgement message. This could lead to callers speaking again or hanging up, assuming the call had dropped.

You can now configure interstitial audio directly from the Voice settings in the Ada dashboard:

  • Four sound options — Choose from Calm Contour, Bright Motif, Pure Cascade, or Slow Gallop. Each sound is optimized for phone audio clarity and designed to feel natural during a conversation. Preview each sound before saving.
  • Adjustable delay threshold — Control how long the AI Agent waits (between 2.0 and 4.0 seconds) before interstitial audio begins playing.

To get started, go to Config > CHANNELS > Voice > Interstitial Audio in the Ada dashboard.

Learn more about configuring interstitial audio.
