Entangled Speech: Semiotic sympoiesis for the posthuman commons

Abstract

In our performance Entangled Speech, we connect the integration of microbial agency into a new complex ‘common good’ with the shared values of language. Drawing on a posthuman commons we aim for a hybrid language that not only processes formal symbols but also interacts with the microbes in the speaker’s mouth. We argue that the metaphors historically used to frame the relationship between microbiomes and speech cannot account for the co-creative material relationship between human speech and posthuman microbial, environmental and biotechnological needs. In our performances, first we harvest sensitized microbes from a speaker’s mouth who had repeated those phonemes, which lead to a deviation of pH of saliva. This makes the microbes sensitive for the further processing: via a spectrogram, phonemes repetitively spoken by the audience drive pumps, which add pheromones to the microbes, the pheromones, which then are faded out. In the microbes, for some replication cycles, an ecological adaptation to the individual phonemes persists, which – in our definition – affirms some phonemes as ecological and others to be deleted, thereby changing the alphabetical order of the input word. Although parts of the process are digitally animated, the major parts develop in real time. We propose ‘microbial speech’ as a category beyond semantic meaning, with ecological qualities such as a transcorporeal mattering between words and the body. We aim at a language becoming a biological state in order to protect its own ecology. We propose a more entangled mode of microbes existing in common with language, affirming posthumanist transversal relations of all living and non-living matter.
