I am sorry to rain on your parade, but the 'hoo-man' mispronunciation is one of the worst tropes in writing Trek aliens when they are specifically established as not speaking English. It makes no sense within Trek rules.
It’s pronounced wrong because it’s intended pejoratively. Clearly.
After all, no Ferengi mispronounces other words. They are very eloquent. Hew-mon is a slur.
It’s fine.
