Real-Time Voice Agent in Production: Cutting Conversational Dead Air with Turn Detection, Two-Pass EOU, and Barge-in
Latency in real-time voice agents isn't just about model speed—dead air comes from endpointing, pause confirmation, audio buffering, and interruption handling. This guide covers production-grade Turn Detection, Two-Pass EOU, and Barge-in using LiveKit, NVIDIA Riva, and Deepgram, with segmented latency metrics and a practical tuning order.
