What is Barge-in?
2 min read · Bolcho
Barge-in is a voice agent's ability to stop talking the moment the caller starts speaking, and to listen to and act on that interruption. Without it, the agent talks over people and forces them to wait — the fastest way to make a call feel robotic.
Barge-in explained
Real conversations are full of interruptions: 'actually, make that 2pm.' A good voice agent detects the caller's voice, immediately stops its own speech, and processes what they said.
Poor barge-in either ignores the interruption (the agent keeps talking) or triggers on background noise (it stops for no reason). Getting it right needs accurate voice-activity detection.
How it works
Barge-in relies on fast voice-activity detection (VAD) to tell real speech from noise, plus the ability to cut the agent's audio playback instantly and re-open the microphone path.
How Bolcho handles it
Bolcho handles interruptions natively as part of its streaming, full-duplex pipeline.
Interrupt any time
Callers can cut in mid-sentence and Bolcho stops, listens and responds — no waiting for the agent to finish, which is essential for busy Indian callers who want to get to the point.
Why it matters for voice AI in India
Indian callers are often time-poor and direct; an agent that can't be interrupted feels like an IVR. Solid barge-in keeps the interaction fast and respectful of the caller's time.
