I myself look for words that I've misspelled while writing something, and write them down for further changes as I work on one of my other projects. I write mainly science fiction and fantasy, so normal names are whatever comes to mind. The other ones......heh. Try randomly making sounds in the back of your throat, or saying things several times fast. You'd be amazed with what you come up with. There is also writing a name which looks weird but sounds normal. That is quite fun to do, depending on the character.
