@octothorpe The vowels aren't the same for me. Both diphthongs, but not the same one. The 'high" vowel in "high" by itself is ah-ee, but in "high school" it's uh-ee, same as in "rice" and "nice" and "splice".
The Cambridge Dictionary does not show a phonetic symbol for my uh-ee diphthong; it has only the ah-ee one, exemplified by "eye", and that's the one it shows for "high", "rice", "nice", and "splice". Wikipedia has a chart giving that same ah-ee diphthong for both "lied" (uses ah-ee in my speech) and "light" (uh-ee in my speech). And the more I look, the more sources I find saying uh-ee is not one of the eight English diphthongs.
I'm not going to start pronouncing "light" as though the vowel were the same as in "pride". It just ain't!
@ancientsounds I'm not quite sure I understand your query. "right" is uh-ee and "ride" is ah-ee for me, with or without [s] involved.
Also: "ice wine" has two different vowels (uh-ee, ah-ee).

Sorry, I was being overly specific when mentioning [s]. The key factor is said to be whether the following consonant is voiceless (s, f, t, p, k) or voiced (z, v, d, b, l, nasals etc). To test this theory, I'm gonna predict that you may say rice, rife, ripe, hike with βuh-eeβ [ΚΙͺ] and rise, arrive, jibe, rile, rhyme with βah-eeβ [ΙΙͺ]. Right (ruh-eet)?
(You're right of course that dictionaries don't show such details in their transcriptions.)
Right, but it's not a clean division; "sider" is [ΙΙͺ] and "cider" is [ΚΙͺ] despite the voiced consonant, and likewise "rider" is [ΙΙͺ] and "Ryder" (an American truck-rental outfit) is [ΚΙͺ].

Wow, that's a really interesting additional wrinkle! Looks like word structure (suffix -er, or not) and/or syllable structure may also be involved. Deserving of further study, not that I have the resources to do it
