Vowel is a,e,i,o,u and H?

I know it must be tough to learn parts of the language when you're deaf. I'll try to help you the best I can. I'm really good at spelling and everything so here I go. No H is not a vowel. Sometimes it's as if the H shouldn't be there because it makes no difference in the word. In the word hour it is like our. This is almost like mine. It could mean it belongs to me "That car is mine." or it could be a place "two people died while trapped in a gold mine." Words can be complicated if they "sound" the same, are spelled the same or have silent letters. Does this help? Do I need to clarify? Just email me if you need more help!
