Are there standard VAD and agentSession settings that are a good baseline for good turn detection

Thanks for reaching out, Muthana. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
For good turn detection in LiveKit, the recommended settings depend on your specific use case. Here are some general guidelines to help you get started: • Custom Turn Detector Model: Consider using a model like
MultilingualModel
or
EnglishModel
combined with Silero VAD for natural conversations. This setup tends to offer great responsiveness with minimal interruptions. • STT-Based Turn Detection: If you're working with AssemblyAI, try configuring
turn_detection="stt"
with tuned parameters such as
end_of_turn_confidence_threshold=0.7
, and pairing it with Silero VAD to better handle interruptions. • Realtime LLM Turn Detection: For integrations like the OpenAI Realtime API, using built-in VAD modes like
semantic_vad
can provide smarter and less interruptive turn detection. • VAD-Only Detection: This is great for language-agnostic detection—setting
min_endpointing_delay
to around 400-500ms usually works well. In most cases, combining the LiveKit Turn Detector Model with Silero VAD strikes a nice balance of naturalness, accuracy, and responsiveness.
