Correct spelling for the English word "Aicken" is [ˈe͡ɪkən], [ˈeɪkən], [ˈeɪ_k_ə_n] (IPA phonetic alphabet).
I apologize, but "Aicken" does not appear to have a widely recognized or established dictionary definition. It seems to be a rare or uncommon term that may not have a specific meaning or usage in general language or specialized fields.
