It's even more complicated than that - welcome to the wonderful world of French vowels! There are three different ways to pronounce "e": just "e", é, and è. Then you have nasal vowels, which is what happens in "différence": "en" is a single vowel sound, and you do not pronounce the "n" at all, unlike in English. There's also "eu", which is yet another sound (as in "deux"). You can find more details about the letter "e" here: http://www.french.hku.hk/starters/fonetik/fiche03web.htm And here are all the French vowels: http://www.french.hku.hk/starters/fonetik/fiche02web.htm I hope this helps!

I'm not sure I understand the question as I repeating the word in french in my head. Although "e" changes depending on the letters around it like in Différence First "é" as an accent so sound like Hey! in English second one is close to the R and N so it's sound like the an in "and" although not exactly (I have no word that comes to mind that mimics that sound perfectly) Although if said with a France accent the Rs would be more present. and the last "ce" following the C making it softer like the word Sea but don't pronounce the A
