Bot continues conversation even when the user does not say anything

Hi everyone,

I’m facing an issue with the OpenAI Realtime API. During a conversation, if the user remains silent, the model still continues speaking. This test can be done directly on Realtime Playground.

In one case, it even changed the language unexpectedly. For example:

USER
Hello, how are you?

ASSISTAN
Hey there! I’m doing great, thanks for asking. How about you?

ASSISTANT
Sure, let’s dive into it. What would you like to chat about today?

ASSISTANT
Of course! 我刚才听到的是中文,对吗?那咱们就继续用中文聊吧。

ASSISTANT
好的,那您最近有什么想聊的话题吗?

ASSISTANT
没问题,那您想了解哪方面的信息呢?

Has anyone else experienced this behavior? Is there a recommended way to prevent the model from continuing the conversation when the user doesn’t respond?
