Americans pronounce scheduled as SKEH-juhld (/ˈskɛdʒəld/). The L in "scheduled" 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 hallmark of natural-sounding American speech. It comes out as SKEH·juhld. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The meeting is scheduled for three o'clock" or "The interview is scheduled for Tuesday afternoon" — more examples below.
