While I'm not sure exactly how "fēənˈketō" would be pronounced (I'm not a native English speaker), that's more correct as to the pronunciation of the "ch" (following the Italian pronunciation).
The pronunciation written in English would be something like fee-ahn-keh-toh, with the accent on the third syllable (keh).
I just found this website in which there are actual recordings of italian (I hope) people pronouncing it. It sounds pretty good to me.
