How to stop Siri from listening to phone calls?

Siri’s listening is defined by the orange circle at the top of the screen.

Every time I make a phone call, the orange circle appears for the duration of the call. Why?

I have turned OFF the Siri listening/learning permissions stated below and have restarted my phone. My phone is current on updates.

Please help direct and inform me what I am missing, and what is allowing Siri to spy and stalk on my phone calls. It must be happening to you, too.
