How to pronounce “data”
Data is pronounced /ˈdeɪtə/. It has 2 syllables, and the beat falls on the first one — deɪ. Below: the syllable split, native audio in both accents, the mistake people actually make with this word, and every individual sound in it explained.
Syllables and stress
Split it into 2 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 deɪ in the right place matters more to a listener than getting every vowel perfect.
Stress pattern Oo — capital letters mark the stressed beats.
The common mispronunciation of “data”
✗ Often said: /ˈdætæ/ — the spelling, read straight off the page.
✓ Actually: /ˈdeɪtə/
Why the two come apart: 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 “data” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.

dSame tongue position as /t/ — tip on the ridge behind the upper teeth — but voice the sound and release it without aspiration.
-
eɪStart at the /e/ position and glide upward and forward toward /ɪ/ — the jaw closes as you say it.
-
tTouch the tongue tip to the bumpy ridge just behind the upper teeth, block the air, then release it with a puff.

əDo almost nothing: leave the tongue in its neutral resting position, mouth slightly open, and make the shortest, weakest possible vowel.
