Not purim torah per se, but as many people dress up like chassidim on Purim, it pays to know how to convert your litvish or American way of speaking into Chassidish.
The first syllable is almost always emphasized. The second syllable, no matter what it is, is almost always pronounced “ih” or eh”, unless one is davening and emphasizing the words.
The following rules only apply for first syllables.
A litvish “uh” becomes a chassidish “ooh”. “Cholent” becomes “choolent”. “Loshon hara” is “looshin hooreh”. “De rebbe is duh” becomes “de rebbe is dooh”.
A litvish “ah” stays the same, but it’s pronounced longer. also, when we litvaks say “Aye” (rhymes with “tie”) (as in mye-riv”, they say “maah-riv”.
A litivish “Ay” (rhymes with “say”) becomes “Aye” (rhymes with “sky”). So Pesach becomes “Pie-sich”.
A litvish “eh” becomes an “ay” (rhymes with “say”). So “emes” becomes “aymiss”. Melech becomes “maylich”.
A litvish or American “oh” becomes “oy”. so Torah becomes “Toyreh”
A litvish “ooh” becomes “ee”. So kugel becomes “keegel”. Kadishuhu becomes kadishihi.
During davening, all the conversion rules apply since it’s said slowly. So “amein yehay shmay rabba” becomes “oomyne yehye shyma rabboo”.
