Are these minimal pairs? Are [e] and [i] separate phonemes? > Looking at everybody's responses so far, it seems as though most of you think these are two separate phonemes. Disagreement seems to be centered around the idea of distinct underlying phonemes that happen to have the same phonetic realization. I'm not sure whether I like this idea or not. The way I've usually seen to find out if two phones are representing two different phonemes is whether they contrast in the same environment. In the example above, the [e] and [i] phones do indeed contrast in the _CV environment. The two phones are not in complementary distribution, as they can both occur in this specific environment. The examples I gave you were not the actual ones I've been looking at. I disguised it like this because I didn't want to start Yet Another English Pronunciation Thread, since I'm actually trying to diagnose something in the dialect of English I speak. By this rendering of things, I'm using way too many vowel sounds, far more than I'd ever put in any conlang.
