The "u" in "duplicate" is pronounced as a long vowel sound, almost like d-you-plicate. Normal pronunciation rules for English indicate that "dup" should be pronounced with a short vowel sound, like "cup". So "dup" sounds wrong. To make a vowel long you can add an 'e' at the end of a word. So: tub or cub have a short "u" tube or cube have a long "u". by analogy, "dupe" has a long "u" and so sounds like the first syllable of "duplicate".
