How to pronounce -ED 🇬🇧 (Full explanation) 

thanks Antonio

The same happened with me❤

Thanks so much teacher.

The Truth about the "ɪd" it's always "ɛd" , but in English when the vowels meet the consonant between them , they're changing and become more closed like "ɪd" or "əd" the same is for the s consonant in this case z sound like "ɪz" or "əz".By the way the vowels in English are different from the other vowels in other languages they are relaxed except the "æ" sound it's always stressed but not always in some accent it's a little relax . This is the reason of the modification vowels in schwa except ah or æ. So schwa will be only the "a" "o" or "u" but never eh or ih but these two end vowels are relaxed and sometimes during a speech will become a schwa , this because eh sound is less enunciated.
