As a native American English speaker, I had no idea that there was a distinction!

(Also, https://en.wiktionary.org/wiki/Rhymes:English/e%C9%AAl is interesting, because its diphthongal glide in accents like mine is much more pronounced than that in e.g. https://en.wiktionary.org/wiki/Rhymes:English/e%C9%AA ... human speech is so hard to parameterize!)
