Americans pronounce goggles as GAH-guhlz (/ˈgɑgəlz/). The L in "goggles" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, a small move that separates 'classroom' from 'native'. It comes out as GAH·guhlz. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The giggly girl struggled with the goggles" or "She forgot her swim cap and goggles at home" — more examples below.
