Hi Judy, it's close to " Joe-awn" - but the awn sounds like "clown", or "haunted" :-) . The tilde gives a nasal tone to the letter it's on. HTH, Rodolpho Pajuaba
PS. Can you tell us phonetically how you pronounce your name? Is it "Joe," as in "GI Joe," or "jah-owe" as it sort of looks like from the spelling, or Hoah allowing for a soft "J"... or?
