I want to know what makes film dialog so distinct from other types of audio recordings
What makes dialog 'distinct' is the person who listens, both 'native speakers' and 'assimilated non-native speakers' are very much tuned to very subtle effects, a slip smack here, a slight nasal tone there... etc. all feed into the human's processing.
On the other hand squealing tires... the Wilhelm scream... while there is a need for quality... do not give the human listener the same sense if there is some form of distortion... in fact some sound FX are very much distorted... to induce a 'visceral' response in the human...
Then there's the recent 'Bane' character in "The Dark Knight Rises"(2012)... where perfectly hearing people would probably like to have had the Wife's closed caption device...
There is the recording of sound, but as a 'director' you will also be concerned with the delivery... if the actors mumble, or have certain speech patterns that are difficult to 'hear' in the resulting track, those should be addressed on the set... or heck, change 'accent' mid dialog, or from shootings to shootings(In "Mrs Doubtfire"(1993) there's a funny exchange between Pierce Brosnan and Robin Williams about the William Character's 'english muddle' accent...)... the sound may be marvelous... but it fails anyway.
