The clear panel allows for light transmission (since we can see through it), what makes you think that having a plastic panel over mouth is going to transmit sound much more effectiverly then cloth?
Experience in my old job from wearing plastic and rubber based masks at certain times.

I depend on seeing more of someone’s face during both in-person and virtual meetings. I can pick up more non-verbal cues, facial expressions, etc.
I keep captions on the TV now too because it helps me since so many are wearing masks while speaking. I’m not complaining about that just stating it affects how I hear them too.
I have 4 different types of masks, two homemade that my wife put together and a couple of different versions of commercial cloth masks.
Non “press against the mouth” becasuse if worn properly the upper part should be over the nose and the lower part over the chin. Those points provide an air gap, never felt the cloth pressing against my lips.
