It reduces the effect. It becomes possible to squelch the loudmouth, take turns talking, hear from everyone. It removes physical intimidation and most body language.
In my experience the "loudmouth" in-person is the same way on a video call. They always get their two cents in, and are sure to jump in regardless of whether or not another person is patiently waiting their turn.
Nobody is suggesting 'robotic' or 'formulaic'.
