Definition
Barge-in is the ability of a voice agent to detect and respond when a caller interrupts while the agent is still speaking, pausing its own speech to yield the floor, just as humans do. Good barge-in relies on full-duplex audio so both sides can be heard at once, plus fast endpointing so the agent yields within a fraction of a second. See our security and compliance guide for how to test interruption handling on a live call.
