Americans pronounce multilateral as muhl-tuh-LA-ter-uhl (/ˌmʌltəˈlæɾərəl/). In "multilateral", 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, and it's one of the defining features of casual American English. It comes out as MUHL·tuh·LA·ter·uhl. Stress falls on the third syllable — keep everything else short and quick. You'll hear it in sentences like "Multilateral institutions play a crucial role in global governance".
