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”.

Advancement – For this word:  the first “A” turns into an true-schwa;  the “d” is (usually) stopped;  the second “a” is short;  the “c” is soft;  the first “e” is silent;  and for the “-ment” suffix – the “e” turns into an i-schwa, and the final “t” is (often) stopped (this is the standard pronunciation of this suffix in The Common Tongue).

– /ə[d]-VæNS-mihn-[t]/ – /ə[d].ˈvæns.mə(ɪ)n.[t]/ – Notice also that the stress is on the second syllable and that the “t” ending (when not stopped) acts as a separate syllable –
