how to make the agent leave the room if there is silence for 30 sec

It seems likely that you can achieve this by using a timer that starts when silence is detected and resets if speech is detected again. You can use the

user_stopped_speaking

event to start the timer and the

user_started_speaking

event to reset it. If the timer reaches 30 seconds, you can call the

disconnect

method to make the agent leave the room. Here's a basic outline of how you might implement this: 1. Start Timer on Silence: Use the

user_stopped_speaking

event to start a 30-second timer. 2. Reset Timer on Speech: Use the

user_started_speaking

event to reset the timer. 3. Disconnect on Timeout: If the timer completes without being reset, call the

disconnect

method to make the agent leave the room. Would you like more detailed guidance or a code example? Sources: - https://livekit-users.slack.com/archives/C07FVFM5NA1/p1731495431.174829 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

code for it @millions-hair-24956

Here's a Python code snippet that demonstrates how to implement a 30-second silence detection to disconnect an agent using LiveKit's VoicePipelineAgent:

import asyncio
from livekit.agents import VoicePipelineAgent
from livekit import rtc

class SilenceDetector:
    def __init__(self, agent, room, participant, timeout=30):
        self.agent = agent
        self.room = room
        self.participant = participant
        self.timeout = timeout
        self.silence_task = None

    def start(self):
        self.agent.on("user_stopped_speaking", self.on_user_stopped_speaking)
        self.agent.on("user_started_speaking", self.on_user_started_speaking)

    def on_user_stopped_speaking(self, *args):
        self.reset_silence_timer()

    def on_user_started_speaking(self, *args):
        self.cancel_silence_timer()

    def reset_silence_timer(self):
        self.cancel_silence_timer()
        self.silence_task = asyncio.create_task(self.silence_timeout())

    def cancel_silence_timer(self):
        if self.silence_task and not self.silence_task.done():
            self.silence_task.cancel()

    async def silence_timeout(self):
        try:
            await asyncio.sleep(self.timeout)
            await self.room.disconnect()
            print("Disconnected due to 30 seconds of silence.")
        except asyncio.CancelledError:
            pass

async def main():
    # Initialize your room and participant here
    room = rtc.Room()
    participant = rtc.Participant()
    agent = VoicePipelineAgent()

    silence_detector = SilenceDetector(agent, room, participant)
    silence_detector.start()

    # Keep the application running
    await asyncio.Event().wait()

# Run the main function
asyncio.run(main())

This code sets up a

SilenceDetector

class that listens for

user_stopped_speaking

and

user_started_speaking

events. It starts a timer when the user stops speaking and cancels it if the user starts speaking again. If the timer reaches 30 seconds, the agent disconnects from the room.

how to manually trigger the agent to leave the room @millions-hair-24956

To manually trigger an agent to leave a room, you can call the

disconnect

method on the room object. This can be done under a specific condition or event in your application. Here's a simple example using Python:

import asyncio
from livekit import rtc

async def trigger_agent_leave(room):
    # Manually disconnect the agent from the room
    await room.disconnect()
    print("Agent has left the room.")

async def main():
    # Initialize your room here
    room = rtc.Room()

    # Trigger the agent to leave the room manually
    await trigger_agent_leave(room)

# Run the main function
asyncio.run(main())

This code snippet demonstrates how to manually disconnect an agent from a room by calling the

disconnect

method on the

room

object. You can place this call in any part of your application where you need the agent to leave the room. Would you like more detailed guidance or further examples? Sources: - Room.disconnect - Room.disconnect 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
