# Barge-in

Barge-in is the voice interaction feature that allows a caller to interrupt an AI Agent while it is speaking — and have the system immediately stop its current utterance, begin listening, and respond to the new input. Without barge-in, customers must wait for the bot to finish speaking before they can respond, which feels unnatural and frustrating — particularly when the customer already knows what they want. Supporting barge-in requires tight integration between TTS playback control and ASR activation. NiCE Cognigy Voice Gateway handles barge-in natively, giving voice interactions the natural rhythm of a real conversation and significantly reducing interaction friction.

For enterprise teams, Barge-In matters because real-world outcomes depend on how the capability is integrated, governed, and measured — not just on the underlying technology. Supporting barge-in requires tight integration between TTS playback control and ASR activation.

## Key Points

- Allows callers to interrupt an AI Agent mid-speech to provide new input
- Requires tight synchronisation between TTS playback and ASR activation
- Eliminates the unnatural 'wait to speak' constraint of legacy phone bots
- Significantly improves perceived conversation naturalness and reduces caller frustration
- Supported natively in NiCE Cognigy Voice Gateway across all deployments
