hero, cheer, fear, searing, here, ...
Most dictionaries will cough up /ɪə/ or even short I for this vowel.
Unfortunately I cannot hear such a thing. Instead I hear /i/.
I am a native speaker (North American), and I also asked two other natives on what they hear. They said pretty much the same thing. I also compared that /ɪə/ sound to what I heard from other natives, and what they said either did not match up, or that my ears suck.
Is this an accent or dialect variation? Or that my ears suck at picking it up and replicating it?
