Or, if you want multiple types of character groupings:

irb(main):001:0> s = 'hello world, you crazy world!'
=> "hello world, you crazy world!"

irb(main):003:0> s.scan( /[aeiou]+|[b-df-hj-np-tv-z]+|[^a-z]+/ )
=> ["h", "e", "ll", "o", " ", "w", "o", "rld", ", ", "y", "ou", " ",
"cr", "a", "zy", " ", "w", "o", "rld", "!"]
