set Siri to always confirm a phone call before it is dial

sometimes, my AirPod misinterprets my words and dials a person in my contacts. This usually happens if I am wearing a scarf or if it's windy outside. Siri does not confirm that I want to call this person and says "calling joe blow...", immediately dialing the number before I have a chance to do anything. Since this happens when I'm using my AirPod, typically my phone is not immediately at hand, meaning the phone call goes through! sometimes in my panic, I shout "no no cancel" and it works, sometimes it does not. Since I have hundreds of contacts in my phone, its always a mystery who Siri decides to call. it hasn't yet been an issue but it's been close!! 

When I ask Siri to dial a number (not a name but for example i say "hey siri call 867-5309", Siri always says "just to confirm, you'd like to call 867-5309?"  how do i ensure Siri ALWAYS confirms that i want to make a call? this glitch is going to get me in trouble one day
