Building Real-Time Voice AI Applications with LiveKit and FastAPI (opens in new tab)

Real-time voice AI demos are easy to make look impressive. Production voice systems are a different problem. The demo usually has one clean interaction, one happy path, and no load. Production has packet jitter, user interruptions, reconnects, flaky speech recognition, delayed TTS, provider failures, and all the little timing issues that make a conversation feel robotic if you do not design for them upfront.
