The min endpointing delay in LiveKit is a configurable parameter that determines how long the system waits before considering a user's turn complete after detecting the end of speech. This delay helps distinguish between natural pauses and the actual end of a user's turn. Default Values: • For AgentSession: Default is

0.4

seconds. • For VoicePipelineAgent and general configurations: Default is

0.5

seconds (500 ms). How It Works: • When the Voice Activity Detector (VAD) detects a transition from speech to silence, and the silence lasts for at least the configured delay, an end-of-turn event is triggered. • This ensures that short pauses in speech are not mistaken for the end of a turn. Configuration Trade-offs: • Lowering the delay makes the system respond faster but may lead to interruptions during natural pauses. • Increasing the delay allows for longer pauses but may make the system feel less responsive. You can configure this parameter when creating an AgentSession or VoicePipelineAgent to balance responsiveness and interruption avoidance based on your specific use case.
