07/25/2025, 11:16 AMAgentSession and resets based on user activity and state changes. Here's how it works:
• Automatic Timer Restart: The timeout restarts automatically in the following scenarios:
◦ When the user starts speaking (state changes from "listening" to "speaking").
◦ When the agent starts speaking (state changes).
◦ When both return to the "listening" state.
• Configuration: The timeout is configured when creating an AgentSession using the user_away_timeout parameter, which defaults to 15 seconds. For example: session = AgentSession(
user_away_timeout=15.0, # Set user as "away" after 15 seconds of silence
# other parameters...
)
• Event Handling: You can listen for the user_state_changed event to handle user inactivity: @session.on("user_state_changed")
def _user_state_changed(ev: UserStateChangedEvent):
if ev.new_state == "away":
# Handle user inactivity
pass
The timeout is managed internally and cannot be manually restarted. Any user activity, such as speaking, will automatically cancel and restart the timer as needed.

07/25/2025, 11:19 AMuser_away_timeout when setting up your AgentSession. It's like giving your process a bit more time to catch its breath:
session = AgentSession(
user_away_timeout=30.0, # Set timeout to 30 seconds
# other parameters...
)
2. Provide User Feedback During Long Operations
Think of this like keeping a friend in the loop during a long story. Just make sure they know what's happening:
• Give a quick heads up that something's in progress.
• Drop a friendly update if things are taking a bit longer.
• Explain any delays so they know everything's cool and working.
3. Handle User Away Events
It's like checking in with a friend to make sure they're still around. Here's how you can do that:
@session.on("user_state_changed")
def _user_state_changed(ev: UserStateChangedEvent):
if ev.new_state == "away":
# Handle user inactivity
pass
else:
# User is active again
pass
4. Example Implementation
Here's a friendly way to check in if someone seems to have stepped away:
async def user_presence_task():
# Try to re-engage the user 3 times
for _ in range(3):
await session.generate_reply(
instructions=(
"The user has been inactive. Politely check if the user is still present."
)
)
await asyncio.sleep(10)
# If no response, close the session
await asyncio.shield(session.aclose())
ctx.delete_room()
@session.on("user_state_changed")
def _user_state_changed(ev: UserStateChangedEvent):
nonlocal inactivity_task
if ev.new_state == "away":
inactivity_task = asyncio.create_task(user_presence_task())
return
# User is active again - cancel re-engagement
if inactivity_task is not None:
inactivity_task.cancel()
By being a bit flexible with timeouts, keeping communication open, and staying attentive to user activity, you'll create a smoother, more user-friendly experience. No more unexpected interruptions!
