The spelling of the word "picken" can be a bit confusing. In IPA phonetic transcription, it would be represented as /ˈpɪkən/. The letter "e" in "picken" is actually silent and serves to modify the pronunciation of the preceding letter "k." The "ck" spelling is used to indicate that the "k" sound is a double consonant, which makes it slightly sharper and more emphasized than a single "k" sound. So, the correct pronunciation of "picken" is actually "pick-en" with emphasis on the first syllable.
