Phone conversations can be messy—callers may interrupt the AI or have background noise. Callupgrade.ai provides voice activity detection and speech settings to handle these situations.

​
1. Voice Activity Detection (VAD)

  • What It Is: A setting that helps the AI wait for the user to finish talking before responding.
  • Configuration: In the assistant’s advanced settings, you can enable or disable VAD.
    • High Sensitivity: AI might interrupt less, but could lead to awkward pauses.
    • Low Sensitivity: AI might talk over the user if they pause mid-sentence.

​
2. Speech Speed & Filler Usage

  • Speech Speed: Some voices allow you to slow down or speed up how quickly the AI talks.
  • Filler Usage: Decide if the AI uses “umm,” “uhh,” or short “mhm” acknowledgments to sound more natural.

​
3. Interruptions

  • If a user starts speaking while the AI is talking, the AI can attempt to stop and listen. However, perfect interruption handling can’t be guaranteed due to phone audio overlap.
  • Encourage shorter AI responses in your prompt to reduce collision with the caller’s speech.

Tip: Conduct test calls to find the right balance of sensitivity and speed. Overly fast responses or overly long monologues can frustrate callers.
