Shattering AI Voice Assistant Lag: How Dual-Model Architecture Achieves Instant Responses

Breaking the AI Voice Assistant Latency Barrier: Dual-Model Architecture in Action Why Does Your Voice Assistant Always Seem to “Ponder Life”? Imagine this scenario: You ask your smart speaker “What’s today’s weather?” only to wait nearly a second for a response. That awkward pause destroys conversational flow. While powerful, traditional large language models suffer from crippling 800ms+ response delays that undermine voice interactions. This article reveals how a 「small model + large model dual-architecture」 achieves sub-200ms responses, using exclusively documented technical specifications from real-world implementations. The Core Challenge: Voice Interaction’s Latency Trap Documented Latency in Traditional Architectures Interaction Scenario Avg. …
