I will write some English words with their Turkish pronunciations, so you can see how ı and ö sounds, in case you are not sure about the English pronunciation, it might help to type and listen to them in google translate or another dictionary.
letter ı
bargain - bergın
angel - encıl
angle - engıl
eleven - ilevın
letter ö
burn - börn
term - törm
I hope it helps. Good luck !
