Vocagender or VOCALOIDgender is a gender directly tied to the VOCALOIDs that exist as avatars for voicebanks of the VOCALOID software. Being vocagender/VOCALOIDgender means that a person feels that their gender is connected to or influenced by a certain VOCALOID, VOCALOIDs, or by VOCALOIDs in general. This can also count FANLOIDs or UTAUs.
