iPhones can’t listen to your conversations if you deactivate Siri’s and other apps’ access to your phone’s mic. TRegardless, Apple has had its privacy mishaps: in 2019, researchers uncovered Siri was eavesdropping even when it was turned off. Apple claimed it fixed this flaw.

You could hear the person you’re calling in the background even before that person accepted or rejected your call. Apple later fixed this flaw.
