The term "babie voce" refers to a specific type of sexual role-play where one or more participants pretend to be a baby, engaging in infantile behavior and sounds. This can include speaking in baby talk, making baby noises, and acting out baby-like scenarios during sexual activity. In some cases, it may involve a partner simulating the act of breastfeeding or bottle-feeding the "baby." It is often used as a form of age play or regression role-play within the context of BDSM or kink communities.
