As a kid I learned much of my vocabulary from reading and being the (relatively) pedantic person I was and am, I fairly carefully enunciated all pronounceable syllables (for example comfortable has four very distinct syllables as opposed to the three that it gets reduced to by many people). I've relaxed that quite a bit over time but I'm regularly asked where I'm from because the asker can't place my accent.

So in my specific case, I mostly don't reduce this vowel.
