The study aims at reinterpreting some sociolinguistic phenomena according to queer and non-binary paradigms, with the help of cyberfeminism and posthuman theories. This theoretical approach is based on the question posed by feminist theorists such as Rosi Braidotti and Donna Haraway whether posthumanism could be a possible mean for escaping the binary gender system. The posthuman lens will be used to reinterpret the relationship between linguistic embodiment, social and biological phonetic constraints, and linguistic performativity for the construction of gender identities. Therefore, the overall aim of the study will be to offer a non-anthropocentric perspective on linguistic facts, reinterpreting the relationship between human and non-human, nature and culture in a profitable way. I will discuss whether the physical body can sometimes limit the expression of gender identities, and if these limits can be overcome through various means, such as the use of hormones, the manipulation of acoustic signals or the help of computer mediated communication (CMC). In this respect, the posthuman approach will therefore consider language as one of many elements, to be seen in relation to a real network of actants and objects. This does mean taking an integrated approach, to account for the performativity of gender not by focusing only on ‘speech’, but rather on the relationship between discourse and materiality in a broader sense.
