yanhe
YANHE is a Chinese VOCALOID developed and distributed by Shanghai HENIAN Co. Ltd, and was released for the VOCALOID3 engine. Created for the VOCALOID China Project, she was illustrated by MQ.
She has short white hair, aqua eyes, and pale skin. She wears a white jacket over a sleeveless top, black shorts with criss-cross belts, stylized loafers and a single frilled thigh strap with a ribbon. Her accessories are headphones and wristbands.
Yanhe's voicebank was originally made for Zhiyu Moke as a shota male vocal. Due to issues at the time, Yamaha took back the possession of Moke's character alongside the other Vocaloid China characters in development from HENIAN. As a result, the company urgently held a second character design contest, where the winning entry suggested an androgynous girl based on how the voicebank sounds, due to it being meant for a boy. This is why Yanhe looks and sounds very androgynous.
她有一头白色的短发、水色的眼睛和苍白的皮肤。她在无袖上衣外面穿了一件白色夹克，搭配交叉腰带的黑色短裤、风格化的乐福鞋和一条饰有丝带的褶边大腿带。她的配饰是耳机和腕带。
延河的声库最初是为智雨莫克作为正太男声而制作的。由于当时的问题，雅马哈从鹤年手中收回了莫克角色以及其他正在开发的 Vocaloid 中国角色的所有权。因此，该公司紧急举办了第二次角色设计大赛，获胜作品根据音库的发音建议是一个雌雄同体的女孩，因为它是为男孩设计的。这就是为什么延河看起来、听起来都非常雌雄同体的原因。
