Barge-in
Letting a speaker interrupt playing audio, so a conversation can be interrupted naturally instead of waiting.
Barge-in is the ability to start speaking — and be heard and processed — while the system is still playing earlier audio, just as people interrupt each other in real conversation. Without it, a translated call or voice agent feels rigid, forcing each side to wait for the other to finish.
Supporting barge-in alongside low latency is what lets translated conversations keep the natural rhythm of turn-taking.
