Very smart #linguistics folx, your attention please 🙏
Given the #IPA həˈləʊ, is there or is there not only "one way" of that being pronounced?
If so, by extension, correct in assuming the phoneme ə can again only be "pronounced" one way?
Why then does the ə on https://commons.wikimedia.org/wiki/General_phonetics#Vowels not sound like the ə in the word hello (represented as həˈləʊ)???
