During Yamaha’s product announcement live stream, AH-Software announced VOCALOID4 versions of their VOCALOID2 catalog—Kaai Yuki, Kiyoteru, SFA2 Miki and Nekomura Iroha. Furthermore, a VOCALOID4 version of Yuzuki Yukari is also in progress, featuring a new whisper voice. According to the latest blog post, the VOCALOID4 version of Yuzuki Yukari will have two voice banks—the normal one and a whisper one. The normal bank will essentially be the same as the VOCALOID3 version, but with growl added. The whisper bank is named “On” (“穏”, which means calm in Japanese). A demo snippet as well as a high resolution image are included in that blog post.
