Fea ~ an h at the front of the word would be pronounced normally, unless you have a really weird accent (yes, I know you have no accent, but still...)
The 'h' sound called the ach-Laut or the 'h' in 'lo
ch' is pronounced as a hard 'ch.' Imagine Eomer saying it in his Scottish accent.

It's also common in German.
The 'h' sound in 'i
ch' called the ich-Laut doesn't occur in English. It's hard to explain, it took my German teacher quite a while to explain it to us, but it's sort of... more hissy than the other 'ch' sound. *Finishes lamely*
I learnt all this but never memorised where to use each one.
