Thankyou, needed to know how to function call

Thanks for the video ! Is there a pre-built method to stop the realtime api automatically when the user is not speaking ( no speech detected) like a timeout attribute or something similar ?
thanks in advance .

I tried this without headphones and the feedback from the speakers made the app think that i was trying to interrupt it.. it is weird cause the nodejs/browser example code doesn't do this. do you have any ideas?

Thanks for this video. So when I play this on my laptop, then the assistant voice sort of interferes with my own voice, and so the experience sort of looks bad! And when I try to plug my earphones, then the voice is not audible in my earphones. Any help?
Also can you also include as how you can do maybe RAG in this- with/without function calling.

I run it without wearing a headphone and it keeps capturing the output audio, causing the echo. Is there anyway I can solve it in the software?
