Turn-Taking and Interruptions: Why Voice AI Feels Human
The hardest part of a voice agent is not understanding words, it is the rhythm of conversation. Learn how agents detect when you have finished speaking (endpointing), handle being interrupted mid-sentence (barge-in), fill awkward silences, and why converting speech to text throws away the emotion in your voice. This orchestration is what separates a natural agent from a robotic demo.

Learn how the STT-LLM-TTS pipeline works, why latency is the central challenge, and the streaming trick that makes a machine respond fast enough to feel like a real conversation.
