OpenAI Realtime API with semantic VAD. Natural overlapping speech, backchanneling ("mm-hmm", "got it"), and <500ms response times.

Emotional Intelligence

Detects customer sentiment in real time. Frustrated? Empathize first. Confused? Slow down. Urgent? Skip small talk. Adapts mid-call.

Every call captures talk-over count, barge-in detection, sentiment shift, response latency, and outcome — feeding a universal learning engine.
