Babiniku and feminized voice in the metaverse

According to the "Social VR Lifestyle Survey 2021," a survey of 1,197 metaverse users jointly conducted by the Swiss cultural anthropologist and Vtuber researcher Ludmila Bredikhina (@BredikhinaLand) and the self-professed "world's first" independent Vtuber and HTC VIVE brand ambassador Virtual Girl Nem (@nemchan_nel) between August 23rd and September 9th, 2021, nearly 80% of users, regardless of gender, reported that they use a female avatar.

Since 89% of the respondents were from Japan, (6% were from North America, 3% from Europe), the survey, while also partly reflecting more universal tendencies of metaverse users, can thus be considered mainly representative of Japanese metaverse culture.

Morever, about 17% of all respondents reported that they modify their voices using technologies such as voice changers. More than half of those users modify their voices to sound more feminine. Surprisingly, 39% of biologically female users with female avatars who used voice changers did so because they wanted to make their voice "cuter." This indicates the tendency of both male and female metaverse users to aspire towards "cute voices" matching their cute avatars.

Although the term originally designated both men and women, today, babiniku バ美肉, short for バーチャル美少女受肉 bācharu bishōjo juniku, literally "virtual incarnation of a beautiful young girl,” is primarily used for men who use "anime" style female avatars in the metaverse and make efforts to feminize their voices through voice changers and other technological means.

In addition to those who rely on technology, there are also those who prefer more "natural" means to achieve this result. As revealed in the abovementioned survey, 5% of respondents indicated that they used methods such as voice training to speak in a different gender voice. Those who do so are known in Japanese as 両声類 ryōseirui, a homophone for 両生類, meaning "amphibian.” The term 両声類, which literally means "ambi-vocal," is sometimes translated in English as TransVoice, although it is not necessarily associated with transgender people.


Babiniku Kōhaku 2021

On December 4th, 2021, two teams of talented singers representing both "factions" of feminized voice performers in the metaverse converged at a special event called バ美肉紅白2021 Babiniku Kōhaku 2021. This was the second year that the event was held. For those unfamiliar with Japanese television, the event's name is inspired by the most famous kōhaku (literally "red and white") competition, the 紅白歌合戦 kōhaku utagassen (Kōhaku singing competition) broadcast every year by NHK on New Year's Eve.

In this case, the red and white teams were represented by four singers who used voice changers and four "ambivocal" singers. Both teams demonstrated their proficiency and singing techniques.

The event was highly successful, as nearly 1,7000 people gathered to enjoy their kawaii voices in the cluster VR platform.
