Verified: Zero Perceptible LagWhat you will learn
- Human conversational turn-taking requires total glass-to-glass response latency under 250 milliseconds.
- ElevenLabs Flash v2 streams 24kHz audio chunks in 40ms increments directly over bidirectional WebSockets.
- Integrated client-side Voice Activity Detection (VAD) detects conversational interruptions and cancels server token queues in under 12ms.
Series: Conversational Audio Systems (Part 1 of 3)
1. The 250ms Human Interruption Threshold
In human conversation, turn-taking pauses average 200 milliseconds. If an AI agent takes 1.5 seconds to respond, the illusion of presence collapses.
Achieving real-time conversational voice requires compressing three steps into a pipeline: speech-to-text transcription, streaming LLM token generation, and real-time neural acoustic synthesis.
