Return function calling results to the client

[hoangtran98]

Hi team,

I have been tweaking with event loop and event emitter to send back function calling results to the client on "function_calls_finished" event, but haven't been able to make it work. As assistant.on() takes a synchronous callback, I am trying to use the event loop to create task. Often it conflicts with TTS segment forwarder, causing it to be destroyed. I am just wondering if there's any ways I could work around this.

Thanks

Hoang
