They don’t have any character design besides the box images and only sing in English. Cyber Diva and Cyber Songman are quite far from that, being pretty much singing tools. Hatsune Miku is the most successful one to date, which is why many people associate Vocaloid in general with her attributes – cuteness, a marketing empire built around the character, a high-pitched voice, anime-style design and Japanese language.

There have been dozens of Vocaloids (voices which work in Vocaloid software) released by various developers over the years. Vocaloid has been around for more than 15 years, having started out as a research project at a university in Spain. Both are English-language voices created from recordings of native speakers of American English.

Cyber Songman and Cyber Diva are two recent English voice banks for Vocaloid 4, also developed by Yamaha. Vocaloid 4 is the current version of Yamaha’s well-known voice synthesis software, which is available as a standalone Windows application, or as a Cubase plugin for PC and Mac systems.
