The common mispronunciation of “one”

✗ Often said: /ˈoʊn/ — the spelling, read straight off the page.

✓ Actually: /ˈwʌn/

Why the two come apart: at least one vowel does not say what its spelling suggests — English vowel letters are not reliable here; also, a consonant letter takes an unexpected sound value here, so reading it "as written" comes out wrong.

This is why reading English aloud from spelling alone goes wrong so often: the letters of “one” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
