This is an article about the Chika software for the VOCALOID3 engine.


Along with the announcement of Ryuto's V3 Gachapoid update; a new VOCALOID, confirmed to be part of the Character Artist Series, was hinted towards. Gobou-P confirmed that the voice provider of the new VOCALOID was a member of an old band.[1]

On September 11, 2014, both the name and design were revealed, along with a demo by Peperon-P.[2]

It was later announced on September 12th that Chika's voice provider is Chiaki Ito (伊藤千晃 Itou Chiaki), one of the female vocalists of the seven-member Japanese pop band AAA.[3]

According to the website, the first shipped packages of Chika's retail version contain a few promotional extra materials.

Package details
Chika is a compact and versatile voice able to fit many genres. Her voice is meant to be cute and firm.

The package also contains demo song data and illustrations.

Vocal traits as noted:
  • According to Peperon-P, her mid-range is very appealing. He listed D3-G3 as her best range, advising for realistic results not to venture too far from this area.
  • She has a wide range from bass to treble.
  • She was designed with any genre of music in mind.
  • Compared to other vocals, Chika can be used with little trouble - even by beginners.
  • At higher ranges of #A4 and beyond, Peperon-P notes that she becomes sharper and more huskier sounding, making this range better for high frequency rock music.
  • Peperon-P also stated that by having largely lower velocity in lower ranges, she can be made to sing ballads.
  • Can cover rocks songs due to her solid and stable bass.[4]
  • At at optimum range of #D5, Chika and kokone have the highest optimum range of any known vocal of VOCALOID3.
Phonetic notes as noted:
  • The length of her consonants is short, which allows her voice to alter quickly and adjust to the melody easily.
  • Her triphones are longer than normal to give smoother results.
  • She has 3 newly added phonemes. This did not impact the VOCALOID3 editor as the 3 new sounds were all triphone related.
  • The vocal itself contains twice the number of phonetic recordings as conventional vocals, resulting in a more natural sounding vocal. This was later confirmed to be caused by the addition of approx 200 triphonetic sounds.[5] Noboru confirmed that she has the most triphones out of their Japanese vocals.
Software issues as noted:
  • Similarities between Vocaloid voicebanks is nothing new, but Chika is commonly noted for her notorious lack of distinguishing traits between her and other vocals - particularly the past Internet Co., Ltd. package, Megpoid. As a result, there were some issues regarding this package that have been expressed by users that are related to this problem specifically;
    • Megpoid/Chika share a very similar tone of voice. They have the same tempo range and they almost also share the same voice range; the only difference in their range being that Chika covers 5 more keys than Megpoid does on the higher octave.
    • As a result of the design, Chika's capabilities were already mostly covered by the existing Megpoid package, who was already much more extensive at this point due to the numerous releases for VOCALOID3.
