It was my second language, do I started out assuming that this was a problem with any language you'd learn.
I do, however, wish natives English speakers were more aware of this for their own sake. Most seem to default pronouncing vowels in foreign words as if it was English, whereas they'd be much closer to the correct pronunciation of they defaulted to pronouncing it like words for any language other than English they might know even a little of. To me this should be one of the first things you learn when learning your second language as a natives English speaker. It even holds true for romanizations of Asian languages like pinyin for Chinese or Hepburn for Japanese
