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”.

Alternative – For this word:  the first “A” is pronounced like the “aw” combination;  the first “e” disappears;  the “a” turns into a u-schwa;  the “t” is a flap-t;  and for the “-ive” suffix – the “i” turns into an i-schwa;  and the final “e” is silent (this is the standard pronunciation of this suffix in The Common Tongue).

– /awl-T’R-nuh-dihv/ – /ˈɔl.tɚ.nə.ɾ(əɪ)v/ – Notice also that the stress is on the second syllable –
