Americans pronounce control as kuhn-TROHL (/kənˈtroʊl/). In "control", the "tr" cluster blends into a "chr" sound — a natural American English pronunciation. This is called the TR Sounds Like CHR, and it's one of the defining features of casual American English. It comes out as kuhn·TROHL. Stress falls on the second syllable — keep everything else short and quick.

Stress falls on the second syllable, not the others. Stretch TROHL — keep everything else short and quick.
