I suspect Gehn, being raised by his mother mostly, would have spoken D'ni rather broken. And Escher pronounced D'ni correctly (Duck-nee) with a hint of Hebrew to it.
how would A'trus be pronounced?
An apostrophe following a vowel represents a glottal stop. So you say the "ay" and stop the air briefly with your vocal chords before saying the "trus", just as you stop the air briefly with your vocal chords between the syllables of "uh-oh".

For example, from Escher's pronunciation, ducknee is closer than dunny but not quite right.
Don't get me started on "ducknee". An apostrophe following a consonant represents a "schwa" from Hebrew. So even if the D'ni glottal stop were as hard as Esher made it sound, it wouldn't have shown up in the word "D'ni". Personally, I'm sticking with my theory that Esher had a bizarre speech impediment caused by being bitten by the snakes in Noloben too many times, and for some reason, it only seemed to manifest itself when he tried to pronounce "D'ni." Stranger things have happened.
