Spanish · Pronunciation Guide
keh — the u is silent, there only to keep the c hard, and the e is the vowel of "bed".
One unstressed syllable in this form — the conjunction meaning that or which slides by without a beat. Its accented twin "qué" means what and does take stress: the accent is not marking a different sound but flagging a question or exclamation word, and it comes with real emphasis in speech.

"Dice que está ocupado" uses "que" to link two clauses, where English can drop the that entirely — Spanish cannot. Notice "está ocupado" runs the final á straight into the o of "ocupado" with no break, and "ocupado" itself is four beats with the stress on PA, the second-to-last syllable, exactly per the default rule.
The instinct is to pronounce the u — "kweh" — because English does exactly that in "queen" and "quick". In Spanish, qu before e or i is silently a k; the u only speaks up in combinations like "cuatro" where it is written after a c. The other confusion is written rather than spoken: "que" and "qué" sound the same, but writing the wrong one turns "he says that" into "he says what".
