Thanks for reaching out, Talha. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Just to share some helpful info with you: the maximum conversation duration in LiveKit is 20 minutes (1200 seconds). When it comes to silence-based chat termination, LiveKit uses different configurable parameters depending on the turn detection mode and integration: • VAD-based detection: The default silence threshold is 0.55 seconds. • Server-side VAD (OpenAI): The default silence threshold is 0.35 seconds. • STT-based detection (AssemblyAI): The default silence threshold is 2.4 seconds. • STT-based detection (Speechmatics): The default silence threshold is 0.5 seconds. On top of that, endpointing delays can range from 0.4 to 6.0 seconds depending on your setup. If you'd like, I’m here to help you adjust these settings or explain anything further—just let me know!

1. Max conversation duration Description: The maximum number of seconds that a conversation can last. 2. Silence end chat timeout Description: The maximum number of seconds since the user last spoke. If exceeded, the call will terminate. 3. Turn timeout Description: The maximum number of seconds since the user last spoke. If exceeded, the agent will respond and force a turn. Where can I configure these setting to change, please guide me what parameters reflect these changes

I'd love to help you out! Could you please share a bit more about which integration or context you're using within LiveKit? For instance, are you working with the OpenAI Realtime API, AssemblyAI, or maybe something else? Knowing this will really help me guide you through setting up the max conversation duration, silence end chat timeout, and turn timeout settings just right for you.

These are configurable settings that I want to give a user, before initializing the call, like admin settings, How can I control these while using livekit?
t
I'd be happy to help you configure these settings in LiveKit! Here’s a friendly guide to get you started: • Max Conversation Duration: You can set this using the
max_duration
parameter in the
RealtimeModel
or
max_call_duration
in the SIP API. For instance, setting
max_duration="45m"
will limit the session to 45 minutes. • Silence End Chat Timeout: This one involves a bit of custom logic. You can keep an eye on user activity and disconnect the session after a certain period of silence, like 30 seconds. • Turn Timeout: You can adjust this with parameters like
min_silence_duration
(for VAD),
max_turn_silence
(for STT), or
silence_duration_ms
(for OpenAI server VAD). For example, setting
silence_duration_ms=800
will end a turn after 800 milliseconds of silence. If you'd like, I can provide specific examples or walk you through any part of this—just let me know! I'm here to help.

I am using openai.LLM, silero.VAD, AgentSession what parameters from the ones provided to you can I control or not control?

When working with
openai.LLM
,
silero.VAD
, and
AgentSession
, I’d love to help you understand the parameters you can adjust to get the best experience: • openai.LLM: ◦ `model`: This lets you pick the LLM model you want to use (like
gpt-4.1
). ◦ `temperature`: Controls how random or creative the responses are (default is 0.8). ◦ `tool_choice`: Decide how tools are used — options are
auto
,
required
, or
none
. • silero.VAD: You actually set this up indirectly through
AgentSession
voice options: ◦ `min_silence_duration`: This sets how long silence needs to be before speech is considered ended (default is 0.5 seconds). ◦ `min_endpointing_delay`: The shortest wait time before ending a turn (default is 0.4 seconds). ◦ `max_endpointing_delay`: The longest wait time before ending a turn (default is 6.0 seconds). • AgentSession: ◦ `turn_detection`: Choose how turns are detected, like
vad
or
stt
. ◦ `voiceOptions`: Here, you can tweak interruptions, endpointing, and user timeouts to fit your needs. ◦ `userAwayTimeout`: Sets how long before a user is considered inactive (default is 15 seconds). If you’d like, I’m here to guide you through setting these up or adjusting them to work just right for you. Just let me know!

I'm happy to help you understand what you can control with your setup: • Max Conversation Duration: You have the flexibility to manage this using the
max_duration
parameter in
AgentSession
. For instance, you can set
max_duration="45m"
to keep the session within 45 minutes. • Silence End Chat Timeout: This one isn’t directly adjustable in LiveKit, but no worries—you can create some custom logic to keep an eye on user activity and end the session after a certain amount of silence. • Turn Timeout: You can fine-tune this with
min_endpointing_delay
and
max_endpointing_delay
in
AgentSession
. For example, setting
min_endpointing_delay=0.4
seconds helps detect when a turn ends after 0.4 seconds of silence. If you’d like, I’m here to walk you through these settings or help with anything else you need. Just let me know!
