I understand some east coast US English speakers differentiate the written ‘wh’ sound when it’s used in words like ‘whip,’ (but I’m not really sure how, and it seems less than subtle when people try to demonstrate it to me, and I have no clue how to make that sound myself - it’s just pronounced straight-up ‘w’ in Midwest/west coast English, ‘wip.’)
On the other hand, I don’t think any US English speakers (or west coast anyway) would pronounce the ‘wh’ in ‘whore’ different than the ‘h’ in ‘hear.’ ‘Whore’ and ‘hoar’ have the same pronunciation to me.
Further, that’s a pretty difficult sound for an English speaker to make after any vowel - particularly the ‘e’ sound. Few words have the ‘h’ sound in the middle, and usually when we see it it’s a foreign word our tongues trip all over. It nearly caused physical pain for me to try, and typically English speakers would try to blunt that sound by replacing with a ‘y’ sound (imagine an American with a bad accent pronouncing the German ‘sehen’ as ‘saiyan’) or a pause beforehand.
