There is a Cambridge American English Dictionary web-site. I was checking pronunciation on some words that have a common sound "æ". Although the sound supposed to be the same, its pronunciation differs in my opinion. I splitted two groups based on how the words sound.
The web-site I used is http://dictionary.cambridge.org/us/dictionary/english.
The first is group:
The second one is:
First question, does the sound really differ or it is me hearing it differently for some reason?
If it is different in the recordings, should that sound sound the same in all the words?
If it should sound the same, may it possibly differ in the recordings because they were taken from people living in different parts of America?
Here is my recording in which I read the words from the list by two ways:
1) the one I heard in an American English phonetics video and from a girl living in Minnesota.
2) the one I taught in school and heard from one guy living in Michigan that said that the first option is more Canadian or something.
Are they both possible ways of saying it and I can choose any? If not, what is most correct way of saying it? And please tell me what sounds I make in the terms of transcription. Thanks!
