The common mispronunciation of “diarrhea”
✗ Often said: /ˈdaɪərheɪə/ — the spelling, read straight off the page.
✓ Actually: /ˌdaɪərˈiːə/
Why the two come apart: the “rrh” is a single /r/ — the “h” is silent — and the stress lands on the third syllable, giving “dye-uh-REE-uh”.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “diarrhea” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.

aɪStart with the mouth open at an /a/-like position and glide up toward /ɪ/, closing the jaw as you go.
