Perception Over Performance: The Voice Agent Latency Paradox

Most voice AI stacks struggle to break the 200ms latency threshold that feels natural to humans. Rather than pursuing expensive engineering to achieve impossible speeds, savvy developers are using psychological tricks—like instant acknowledgments and conversational fillers—to make their agents feel responsive even when they're objectively slow. This shift from raw performance to perceived experience opens a practical path for teams building voice AI without unlimited engineering resources.
