Corespeechd sending massive things to internet

MacBook air 13"

So i was using safari and notice that the MacBook was EXTREMELY slow

So i checked the activity monitor

Found out that a stuff called "corespeechd" was sending 2.7MB of stuff to internet

And i tried to close it but it didn't work

And i tried the steps on apple discussions about the unchecked ask siri

But unfortunately it doesn't work.

Can anyone help me to solve the problem?

Thanks
