Hello, The letter transcribed e seems to have two allophones or sounds, one of them being closer to [æ] than the regular sound of e. The open sound [æ] seems to occur in certain words. Sometimes the two sounds seem to alternate in one word (e.g. the word defter pronounced [deftær]). I don't know if these two sounds alternate freely or if there is some rule for them. I assume that they are free variants since they are transcribed by the same symbol in the alphabet.
