Americans pronounce study as STUH-dee (/ˈstʌdi/). In "study", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth.

Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "I have to study for my math class" or "Marine biologists study the health of the ocean" — more examples below.
