The genital voice is the voice that the subject acquires in adolescence. The term genital evokes the gendered character of the voice both in its biological and psychic nature. But while biology imposes a new voice on the adolescent, the temporality and resistances of the mind are not the same when it comes to accepting this pubertal transformation. Based on the treatment of a 13-year-old boy, the author shows how, in analytic work with adolescents, listening to the adolescent’s voice and more broadly to the relationship that the latter has with it, and also with the analyst’s voice, can help enrich the analyst’s listening abilities. He will be able to hear more closely the quality of the path that the adolescent is pursuing to integrate psychically the genitalization of his body.
