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”.

Advanced – For this word:  the first “A” turns into a true-schwa;  the “d” is a flap-d, but is (often) stopped;  the second “a” is short;  the “c” is soft;  and since the root-word ends with the sound of the letter “s” – the “e” of the “-ed” ending is silent and the “d” is pronounced like the letter “t”.

– /ə[d]-VæN-st/ – /ə[ɾ].ˈvæn.st/ – Notice also that the stress is on the second syllable and that the “st” ending acts as a third syllable –
