event.
Here’s a simple example of how you can do that:
@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
# Cancel the inactivity task when the user becomes active
if inactivity_task is not None:
inactivity_task.cancel()
inactivity_task = None
This way, the inactivity task gets canceled right when the user is active again, so you won’t get any unnecessary reminders or session closures. Hope this helps!

event is only picking up the "away" status and missing out on active moments like talking or sending messages, don’t worry — let’s walk through a few things to check together:
• VAD Configuration: Double-check that the Voice Activity Detection (VAD) module is properly set up and turned on in your session settings. This little helper listens for when the user is speaking.
• Audio Input: Make sure the user’s microphone is working fine and that audio is actually coming through.
• Timeout Settings: Take a look at the user_away_timeout
setting. If it’s set too low, the system might mistakenly think the user is inactive.
• Event Subscription: Verify that your app is correctly subscribed to the user_state_changed
event and that your event handling code is set up properly.
By checking these points, you should be able to catch those active states and make sure the inactivity task gets canceled when it should. If you need a hand with any of this, just let me know!fresh-painting-88343

event only fires when your app explicitly changes the user state with methods like commit_user_turn()
, interrupt()
, or clear_user_turn()
. This way, you have full control over exactly when the event happens, which is super handy for things like push-to-talk scenarios.
To make sure the inactivity task stops when the user becomes active again, you’ll want to call these methods to update the user state. For example, commit_user_turn()
works great when the user starts speaking, and interrupt()
is perfect for handling interruptions.
If you’d like, I’m happy to walk you through more details or share some examples to help you set this up.
