Americans pronounce curator as kyoo-RAY-ter (/kjʊˈreɪɾər/). In "curator", 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, the kind of sound shift that makes everyday speech feel effortless. It comes out as kyoo·RAY·ter. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "The curator explained the historical context of the artwork".
