The pronunciation of any word in English (or any language at all) is not Universal.  This is because there are many different dialects of The English Language — both throughout America, and also world-wide.  The pronunciations that are presented on GiveMeSomeEnglish!!! are based-upon a combination of both “common usage”, and the most neutral accent used in The International Common Tongue — a.k.a. “American English”.

Advertisement – For this word:  the “A” is short;  the “d” is a flap-d, but is (usually) stopped;  the “e” disappears;  the first “i” is long;  the “s” is pronounced like the letter “z”;  and for the “-ment” suffix – the “e” turns into an i-schwa;  and the final “t” is (usually) stopped (this is the standard pronunciation of this suffix in The Common Tongue).

– /æ[D]-v’r-taiz-mihn-[t]/ – /ˈæ[d].vɚ.taiːz.mə(ɪ)n.[t]/ – Notice also that the stress is on the first syllable and that the “t” ending (when not stopped) acts as a fifth syllable –
