• Use a SILENCE_THRESHOLD = 5 seconds.
• Run a periodic background task that checks if now − user_last_spoke_time > SILENCE_THRESHOLD. If so, call session.say("Are you still there?", allow_interruptions=True) (or your preferred prompt).
• Reset user_last_spoke_time when the user speaks so the timer restarts.
Would you like a code example in the language you’re using (JavaScript or Python)?

04/14/2026, 9:10 AMMultilingualModel turn detection and set endpointing so the agent treats ~5s of silence as a turn end and can respond.
Example Python snippet (adjust names to your codebase):
from livekit import AgentSession, TurnHandlingOptions, MultilingualModel
import silero.vad as silero_vad
# load VAD
vad = silero_vad.VAD.load()
session = AgentSession(
vad=vad,
turn_handling=TurnHandlingOptions(
turn_detection=MultilingualModel(), # your multilingual turn detector
endpointing={
"min_delay": 5.0, # treat high-confidence end as 5s
"max_delay": 5.0, # treat low-confidence end as 5s
},
),
# ... other config: stt, tts, llm, callbacks, etc.
)
# Start session as you normally would. When turn detection signals end-of-turn
# after ~5s of silence, the agent can automatically call session.say() or invoke
# your response handler to speak again.
Notes:
• Setting both min_delay and max_delay to 5.0 makes endpointing trigger around 5s regardless of confidence.
• Keep vad enabled so silence is detected locally; MultilingualModel() provides semantic turn detection.
• If you want the agent prompt to allow interruption, use session.say("...", allow_interruptions=True) in your response handler.
Do you want a full example showing the handler that calls session.say() when the turn ends?

◦ Lives inside TurnHandlingOptions.endpointing (used with MultilingualModel, STT, or custom turn detectors).
◦ Controls the minimum seconds the turn detector will wait after detected end-of-speech before treating the user’s turn as finished.
◦ In Python this can participate in dynamic endpointing (the detector may adapt timing but will not go below min_delay). Use this when you’re running turn_detection=MultilingualModel().
• min_endpointing_delay
◦ A legacy/global-style setting used in older or simpler VAD-only setups.
◦ Also expresses a minimum post-speech delay, but it’s not part of the modern TurnHandlingOptions API and is commonly used with plain VAD/fallback endpointing.
◦ It behaves like the older min/max_endpointing_delay pair (defaults ~0.5s / 6.0s).
Practical guidance for your setup (Python, VAD + MultilingualModel):
• Use endpointing={"min_delay": 5.0, "max_delay": 5.0} inside TurnHandlingOptions to make the MultilingualModel treat ~5s of silence as turn end.
• Note: these parameters control when the user’s turn is considered finished. They do not by themselves make the agent proactively speak after silence — they simply let the agent conclude the user turn after ~5s, at which point your agent logic can respond (e.g., call session.say(...)).
Would you like a short Python snippet showing TurnHandlingOptions with min_delay=5.0 and a sample turn-end handler that invokes session.say()?
