I'm learning IPA and am surprised that some standard American English sounds which seem subtly different to me are all recorded as [aɪ].
Consider the phrase "I like the night", which I understand would be rendered as [aɪ laɪk ðə naɪt].
But to my ear the vowel sound in "I" is pretty different from the sound in "night", which is closer to the sound in a word like "yikes".
Am I hearing a difference that isn't there? Am I hearing a difference that is there, but is represented by diacritic markings I haven't yet learned? Or something else?
