In this article, we explore how a posthumanist stance has enabled us to work a different consideration of the way in which voice is constituted and constituting in educational inquiry; that is, we position voice in a posthuman ontology that is understood as attributable to a complex network of human and nonhuman agents that exceed the traditional understanding of an individual. Drawing on the work of Deleuze and Guattari, Barad, and Bennett, we present a research artifact that illustrates how this (...) posthuman voice is productively bound to an agentic assemblage. The reconfiguration of a posthuman voice with/in an educational research artifact further enables us to explore various analytic questions: What happens when voice exceeds language and is more than vocalized words emanating from a speaking subject? If the materiality of voice is not limited to sound, how do we account for it? That is, how might the materiality of voice be located in the space of intra-action among human and non-human objects? We conclude with implications for thinking qualitative methodology in education differently. (shrink)
