RIDDLE ME THIS

From your lips to their ears, I carry thoughts across the gap.

Written, spoken, or typed, I fall apart when no one listens.

Take me out, and both teams and marriages start to crumble.

I'm the bridge between what you meant to say and what they took from it.

Every email, phone call, and conversation carries a piece of me.

What am I?
