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”.

Allied – For this word:  the “A” is short;  the “ll” combination is pronounced simply like the single letter “l” (this is the standard pronunciation of this letter combination in The Common Tongue);  the “i” is long;  and since the root-word ends with the letter “y” (converted to an “i” for the addition of the “-ed” ending) – the “e” of the “-ed” ending is silent, and the final “d” is a flap-d, but is often stopped.

– /æ-lai[d]/ – /æ-lai[d]/ – Notice also that the stress is on the first syllable –
