Americans pronounce botany as BAH-tuh-nee (/ˈbɑɾəni/). In "botany", 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 hallmark of natural-sounding American speech. It comes out as BAH·tuh·nee. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He studied botany to learn more about plant biology".
