The word "ackman" is spelled phonetically as /ˈæk.mən/. The "a" is pronounced like the "a" in "cat," and the "c" is pronounced like a "k" sound. The "k" and "m" sounds are separated by a schwa sound, represented by the upside-down "e." In English, the lack of standardization in spelling can make words difficult to pronounce when they're not commonly heard. However, with the IPA phonetic transcription, it's possible to accurately represent the pronunciation of any word, including "ackman."
