Western voice is historically de-agentialized, that is, gendered female, opposed to performer self-listening, de-privileged relative to composition and rendered ocularcentric by recording technologies. However, by employing sound technologies as prosthesis to the vocal body, and by self-listening to manage the body-prosthesis relationship, contemporary extended voice practitioners figure as cyborgs reclaiming vocal agency, that is, input into mediation of and by one’s technologized vocal body.
