Syllables and stress
Split it into 4 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 keɪ in the right place matters more to a listener than getting every vowel perfect.

The common mispronunciation of “duplication”
✗ Often said: /ˈdʌplɪkætɪɑːn/ — the spelling, read straight off the page.
✓ Actually: /ˌdjuːpləˈkeɪʃən/
Why the two come apart: the stress lands on the third syllable (“keɪ”), not on the first one — putting the beat at the front is the mistake almost everyone makes; 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; 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 “duplication” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
