Halsey

Halsey is the name of a Vocaloid software voicebank developed by Crypton Future Media and its official moe anthropomorph, a 25-year-old woman. Gaining attention from self-released music on social media platforms, she was deployed by Astralwerks in 2014 and released her debut EP, Room 93, later that year.

Halsey was the fifth vocaloid developed by EMI in its Project Singer, an effort to create a fully digital, AI-controlled singer. After her "beta test" for Astralwerks was completed, she was assigned to Capitol Records for a full roll-out in 2018. She is considered the most successful vocaloid since Avril Levigne.

Due to limitations in holographic technology, EMI has a side-project called Real Halsey where real-life, human "Halsey" doubles play out her live performances. Although the Halsey doubles strongly resemble the vocaloid, their singing is not real.

Halsey Double Controversy
The FBI has investigated reports that Halsey doubles are regularly "disposed of" by EMI. An online community has sprung up to identify new Halsey doubles every time they appear and to track their life cycles. According to the community, which refer to themselves as Hal Monitors, the average Halsey double lifecycle is 16 days.

EMI has denied "eliminating" Halsey doubles but has admitted that they are employed for short periods before returning to lives of anonymity.
