Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce studying as STUH-dee-uhng (/ˈstʌdiɪŋ/). In "studying", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, a small move that separates 'classroom' from 'native'. So instead of STUH·tee·uhng, you get STUH·dee·uhng. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He's studying psychology at the university" or "He's been studying English for almost three years" — more examples below.

Stress falls on the first syllable, not the others. Stretch STUH — keep everything else short and quick.
Don't pronounce the second syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
