Template:Hiyama Kiyoteru V2 voicebank

Kaai Yuki and Kiyoteru were designed to be Vocaloids that had human-esque traits about them. His treble range is supposedly smooth, which allows for an easier usage of the higher octaves. He has the softest of the Vocaloid male voices within the Vocaloid 2 voicebanks. Also he has clear Japanese consonant sounds and stable voice.

He is not good at singing in a low voice as a male singer and the beginning consonant sounds get shorter as well as with other AH-S vocaloids. Because of this he is often said upon his inital release that he was not easy for beginners to use. A particular noted weakness of his voicebank is that he cannot produce a satisfactory low masculine vocal tone.
