I am using manual turn detection for lk agent. In case of client performs an end_turn wherein I perform a session.commit_user_turn() with a timeout. My question is what happens after the timeout is exceeded.

What if after the timeout, there is no transcript at all.

I understand that dealing with timeouts and empty transcripts can be a bit tricky, so let me walk you through how the system manages this situation in `session.commit_user_turn()`: • When a timeout happens and no transcript is captured, the system gently handles it without throwing any errors or warnings. It simply treats the lack of a transcript as a valid scenario—for example, if the user didn’t speak. • If there’s any interim transcript available, it gets added to the audio transcript. If not, the transcript just stays empty. • Then, the system triggers end-of-turn detection using that empty transcript. • The

on_end_of_turn

hook is called next, passing along the empty transcript. • In your agent’s

on_user_turn_completed

callback, you have the opportunity to manage this empty transcript case—like raising a

StopResponse

if you want to prevent the agent from replying. This approach helps the turn wrap up smoothly, even when no speech is detected. Plus, it gives you the flexibility to add your own custom handling for empty transcripts in your application logic. If you have any questions or want to explore more about this, I’m here to help!
