The spelling of the word "Acopon" is an uncommon one, and may be confusing for some due to the presence of the silent "c" at the beginning. The correct pronunciation is /əˈkoʊpən/. The IPA transcription reveals that the first syllable is unstressed and pronounced with a schwa sound. The "c" is silent, as it often is in words borrowed from Spanish. The rest of the word is straightforward and pronounced with the usual English vowel sounds.
