This is an article about the SONiKA software for the VOCALOID2 engine.


Zero-G felt that a young, carefree singer would make for an overall interesting VOCALOID, providing the fresh and innocent voice that professional singers do not provide. She had several demo songs released.

Global ExportEdit

Sonika has had a Chinese version produced, distributed by E-Capsule Co. Ltd in Taiwan. The Chinese edition came with new boxart. Users can choose to use the original English or Traditional Chinese interface.[1] Because of this, it has an instructional DVD and a comparative table of English and Chinese phonemes in an explanatory leaflet. The leaflet shows her accessibility to about 90% of the Chinese pronunciations. The leaflets were produced by E-Capsule for users in Taiwan to make it easier for buyers to produce natural Chinese from her voice. This version when displayed at its announced convention on 24 and 25 July 2010 came with limited stickers and posters.[2] On August 1, 2010, Sonika was released in Taiwan and became the first VOCALOID to be released in Greater China.[3]

She had several demo songs: "Little Forest", "夢想天堂", "Press that accelerator" and "Scenery".

Final RetirementEdit

At the end of 2015, it was announced that from March 31, 2016, VOCALOID2 was being retired and no new serial codes were be issued by Yamaha. Zero-G announced that they would continue to issue import codes to legitimate owners of Prima, SONiKA and Tonio.[4]

Package details
SONiKA is a VOCALOID designed for Pop Music. She has a strong British accent and is better suited for late 20th century pop. She sings with a soft and innocent sounding voice. She is a Mezzo-soprano singer. Unlike past Zero-G VOCALOIDs, SONiKA was not intended to be based on a professional singer and does not produce professional singer quality results in the same way Prima did.

She is the only Zero-G vocaloid known to have been created by processing her vocals and this was done as a experiment. This also makes her among the least realistic sounding of the English Vocaloid2 vocals for that era, compared to her predecessor Prima who was much more realistic sounding. As a result, she more closely mimicked the style of Japanese Vocaloids mostly being released at the time from the Character Vocal Series and was te closet English only Vocaloid to do so in that engine version.

Her software comes with the VSQ file for her song "SONiKA says".

Buying the Taiwan version gives a Chinese interface for Vocaloid2 and a guide on how to match her sounds to sing in Chinese (90% accuracy possible if guide is followed closely). This is the only way to obtain the Chinese version of the interface.

Vocal traits as noted:
  • She was more flexible than most other English VOCALOIDs for VOCALOID2, not having a voice so specific to a genre.
  • Sound on sound writer John Walden says her higher vocals were better than lower and labelled "C4" as the best octave. He also stated that in his opinion her vocals seem best for "bubblegum pop", [5]
  • At a optimum known vocal range of #D5, both Megurine Luka and SONiKA joint hold the title of second highest VOCALOID 2 vocal
  • She is unstable when she reaches her optimum range and SONiKA will suddenly change from being soft and muffled to loud and clear (one range reported where she is clear is #B2 to #G3).[6]
Phonetic notes as noted:
  • She has a number of pronunciation issues linked to a number of weak consonant related sounds, which are made harder to use because of the softness of her vocals.
  • According to Zero-G, SONiKA has every vowel sound combination possible needed for English.
Software issues as noted:
  • Something often picked up upon is SONiKA overall vocal commonly suffers from noise issues that, while possible to remove, affects her raw vocals.
  • The overall quality of her vocal is arguable. SONiKA was ranked 4 out of 5 stars in her review by Sound on sound and was recommended as a quality product. However, users and VOCALOID fans often recommend other English VOCALOIDs over SONiKA.
  • When imported into VOCALOID3, SONiKA develops a Aspirated Plosive glitch. She also suffers from a "h" phoneme related glitch.
