This thesis reflects on the status of the voice in contemporary cinema by examining a selection of audiovisual works whose unique artistic procedures invite investigation — especially with regard to what has been recognized as spectral manifestations of the acousmatic voice. The work is composed of three complementary essays, which investigate how and with what aesthetic-political effects these productions subvert historically calcified forms of depriving the word of any corporeality, notably of the materiality of the voice. With this horizon, the study delves into the following creations: JL s passion (2016), by Carlos Nader; Dead ones, do you live? (2018), by Gabriela Greeb; The image book (2018), by Jean-Luc Godard; and Dazed flesh (2019), by Grace Passô and Ricardo Alves Jr. By attending to the ways in which these films work with and think about the vocal matter, we distinguish and explore three interconnected manifestations of the acousmatic voice: (1) we propose to think about the treatments given by Nader and Greeb to the voice archives of Leonilson and Hilst as spectral vocobiographies, with emphasis on what evolves in between presence and absence, individual and collective, fiction and reality; (2) we derive the notion of a tactile buzz from the singular ways in which Godard combines the myriad of voices he summons, as yet another means to respond to the imperative that opens the film, namely, to think with the hands; and finally, (3) we reflect on the invention of a polymorphous voice in the medium-length film by Grace Passô and Ricardo Alves Jr., which, triggered by homonymous staging (2016) and book (2018) by Passô, has as its surprising protagonist a voice with the power to transit through different subjects. I show how, by mobilizing the materiality of the voice through different paths and with different emphases, the studied films act in order to displace entrenched — and passive — modes of listening.
