* "Hoe" is pronounced like the word "hoe" but with a slightly shorter "o" sound.
* "hn" is pronounced as a single sound, similar to "n" but with a slight "h" sound at the beginning.
So, the complete pronunciation of "Hoehn" sounds like "hohn".
Think of it like a combination of the "ho" in "home" and the "n" in "sun", with a subtle "h" before the "n".
