One problem is that the people mixing the audio already know what is being said:
Top-down processing
(or more specifically, top-down auditory perception)
This refers to perception being driven by prior knowledge, expectations, and context rather than purely by sensory input. When you already know the dialog, your brain projects that knowledge onto the sound and experiences it as “clear.”
