Sub-300ms Latency Budgets in Real-Time Conversational Voice AI
Breakdown of Voice Activity Detection (VAD), Streaming ASR, Time-to-First-Token (TTFT), and Neural Text-to-Speech execution time budgets.
Why Humans Feel a Lag Above 400ms
In natural human dialogue, conversational turns take between 200ms and 280ms. The moment an automated system takes 700ms or 1200ms to reply, users speak over the bot. Vext achieves a 265ms total turnaround budget by running pipelined acoustic streaming directly in local memory.
