How do I autoduck two vocals in conversation?

Hi,

When recording an interview I use the camera's audio to sync two independent lav mic tracks, one for each talent. At the moment I manually go through the two tracks, slicing out audio from track one when track two speaks, and vice versa. Occasionally there is overlap but on the whole this works. However, a one hour interview can take many hours to edit.

Is there a way of autoducking two people in conversation using two independent audio tracks? I figured there has to be a much easier way to do this than my current methodology.

I appreciate ducking normally refers to music but in this instance there is no music, only two people in conversation. Obviously each mic picks up both people talking, one louder than the other.

Any pointers gratefully received.
