The earliest known information related to CYBER DIVA dates back to the VY2 release in 2010 with an article stating that a pair of English VY vocals were announced for future development. At the time, the developers did not know if they would re-use past samples or make a new vocal entirely. CYBER DIVA was later confirmed to be the female of the pair or "VY3".
CYBER DIVA was produced in light of research into common complaints towards past pre-V4 English VOCALOIDs. This included the frustrations that came with the mixed British and American phonetic system the VOCALOID engine used for its English VOCALOIDs. It was also discovered that English VOCALOIDs often did not produce the correct sound to match the phonetics in use. This was caused by accidents in the construction of the VOCALOID either during the recording process or the VOCALOID development process.
Several candidates were tested as possible vocals for the new library. During this process, it was noted that there were many missing sounds or unusual sounds that were not expected to be present. In the constructed libraries, there were very clear and expressive sounds. The "Aspiration Problem" that had plagued past English VOCALOIDs was addressed and fixed, which also resolved the complications of sounds not matching the input symbols. They did not address the issue of expressive tones until they recorded the correct sounds for the corresponding phonetic symbol.
In February, the recording script was rewritten. The aspiration problem was fixed in the new script and the sounds were compacted for easier control over the phonetic data.
In March, two more singers were recorded using the new script. The new script was shorter than the previous one and was more difficult for any singer to produce. However, the script's new results sacrificed expression for clarity and mislabeling was gone. Further tweaks to the scripts were done as recordings went ahead.
Once the voicebanks were brought to a reasonable quality, the team working on CYBER DIVA was given the choice between continuing with the current singers or finding a new one. CYBER DIVA was recorded in 6 pitch layers. She has 3 main pitches with an additional 3 sets of vowel pitches or stationaries. They added 231 different triphones per pitch; more than any other English library released before.
The vocal was tested by two hired English teachers. They were hired since over half the team were Japanese. Incorrect sounds that the Japanese members did not detect would be confirmed by the non-Japanese members instead. Due to the mix of British and American sounds, CYBER DIVA did not always sound good when the dialects were mixed. She included the schwa sound which is not included in all English vocals despite the fact that the phonetic was still used by the voice. A custom dictionary was made for her which was worked upon in July. Due to its size, they fixed the library to load faster. The dictionary was finalized in October 2014.
CYBER DIVA was tested for release on March 13.
CYBER DIVA was revealed on the January 21, 2015 as an American accented female produced by YAMAHA and 5 demos were released. Utata-P reported that their demo, "YOU WILL SEEE.", was done with the default settings and no auto-tuning. She was released on February 4, 2015.
Despite being created with a new YAMAHA script, it was noted that other English VOCALOIDs may not be using the same script. As of February 2015, the new script was not shared with RUBY's developer at the very least.
On October 31, 2016, CYBER DIVA was offered as a starter pack with the VOCALOID4 editor or the VOCALOID4 editor for Cubase. In addition, she was offered in another set: a starter pack containing her vocal and CYBER SONGMAN along with either the VOCALOID4 editor or VOCALOID4 editor for Cubase.

CYBER DIVA is geared towards professional producers. Her voice has an American accent and demonstrates increased clarity over past pre-V4 English VOCALOIDs. She has only one voicebank and cannot use XSY, and is designed for a variety of genres.
