On March 25, 2013, a competition was carried out to have a selection of avatars to choose from. The characters were designed based on the small demo provided, a feminine sounding vocal singing a well known Chinese classic, Mo Li Hua (Jasmine Flower). Fans could select and vote on the design they liked best. The second contest functioned similarly to VOCALOID CHINA's first contest in 2012 (where the winner was Luo Tianyi). The first round finished at the end of April.
On May 13, out of 666 entries, only 15 were selected as finalists. On June 6, the 4 runner ups were announced and with YANHE as the grand winner. Thus, she became a VOCALOID.
After some time since the winning announcement, YANHE's design was readjusted, but not as drastically as the VOCALOID CHINA characters before her. An album called The Stage 1 was revealed in June, featuring early use of YANHE's vocals. Within two months time since the contest ended, she was officially released on July 11, 2013.
YANHE is a young, deep-toned female vocalist. Originally, she was intended to be a young masculine vocal, similar to Kagamine Len, which is why she sports a deep tone of voice.
Vocal traits as noted:
Her voice is a husky, yet young teenage voice that can provide a lower accompaniment to higher vocals such as Luo Tianyi.
Since there is huskiness with her voice, she may suffer a "rasp," similar to the Megpoid rasp issue.
She is described to have an androgynous voicetype and has a fresh boyish-voice.
Phonetic notes as noted:
YANHE may have stress on "a"'s and other vowels, giving her a more "professional" feel.
Pronunciation of "u" sounds ("g u a", "k_h u a") may suffer small-time lag and further editing may be needed.
Almost all pure vowel diphthong/triphtong syllables started with [i], [u] and [y] (in Chinese phonology, zero consonant syllable with a glide, like [uo] [iAU]) suffer small lagging due to wrong timing settings. Further editing is needed for accurate rhythm alignment.
