I did some research and found out that Rio isn't a vocaliod, she's actually a character made to promote Sanrio's Hello Kitty products, along with Nekomura Irona (http://www.youtube.com/watch?v=vUFeVpoWqnw&feature=related). Rio doesn't have a voice but Iroha does, because she became a vocaloid after Sanrio made an agreement with Ah-software.
Also (I'm not sure on this) but they are both "kittylers" and many people refer to Rio as "Kitty'er". There's more than one kittyler, and you can see them on the official site. (with-kitty . com)
