Is there any way to make dialog recorded inside (with a slight echo from the walls) sound like it was recorded outside? I shot a scene recently on a set that I built in my house. The dialog clearly sounds like it was shot inside. Is there anyway to remove the slight echo and make it sound like it was shot in a wide open space? Basically removing the echo, I think.

Thank You,

In a short answer...no.
You can attempt to remove some of the echo, but it will definitely sound processed and not "right."
The human ear is incredibly perceptive...

Theoretically you could ADR it (re-record the audio) but it's probably not worth doing.
