LLM Real-Time Voice Input in Production: Low-Latency Recognition with VAD Segmentation, Partial/Final Reconciliation, and Audio Contracts
Real-time voice applications face challenges beyond model accuracy. This article systematically breaks down how to build an observable, rollback-capable low-latency speech recognition pipeline—from audio format contracts and VAD segmentation strategies to Partial/Final state reconciliation, timestamp replay, and real-world noise evaluation. Designed for LLM, generative AI, and real-time Agent practitioners.
