It's funny because as American kids are learning to read and ask what a word is we are told "sound it out". It usually works. But it definitely doesn't work the other way around, trying to spell a word by how it sounds. I had a Portuguese friend online once that spelled "awesome", "hawsom" and we had a good laugh because he felt embarrassed but we had to assure him it's still spelled wrong but still sounds right if you read it out loud.
