Syllables and stress
Split it into 3 beats. The highlighted syllable is the strong one: say it louder, longer and a touch higher in pitch, and let the others fall away. English is a stress-timed language, so getting daɪ in the right place matters more to a listener than getting every vowel perfect.
Stress pattern Ooō — capital letters mark the stressed beats.
The common mispronunciation of “diocese”
✗ Often said: /ˈdɪɑːkiːs/ — the spelling, read straight off the page.
✓ Actually: /ˈdaɪəˌsiːz/
Why the two come apart: the silent final “e” (it lengthens the vowel instead) is not pronounced, even though the spelling begs you to say it; also, the unstressed vowels flatten all the way down to /ə/ — English swallows them, so they never sound the way they are written; also, at least one vowel does not say what its spelling suggests — English vowel letters are not reliable here.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “diocese” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
