Americans pronounce couple as KUH-puhl (/ˈkʌpəl/). The L in "couple" 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, and it's why Americans sound more relaxed than the textbook. It comes out as KUH·puhl. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The sweet couple booked the honeymoon suite" or "May I offer my congratulations to the happy couple on their engagement?" — more examples below.
