You are mistaken. There IS a version of "forte" that is correctly pronounced "fortay" and that is the musical term for loud, which is Italian.
The correct pronunciation of "forte" as in an area of strength or speciality is "fort". Older dictionaries will give this as the correct pronunciation but more modern and especially online dictionaries sometimes give "fortay" as an alternate pronunciation.
