Syllables and stress

The common mispronunciation of “acetate”
✗ Often said: /ˈæketeɪt/ — the spelling, read straight off the page.
✓ Actually: /ˈæsəˌteɪt/
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.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “acetate” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.

tTouch the tongue tip to the bumpy ridge just behind the upper teeth, block the air, then release it with a puff.
