In the priority area »Philosophy and the Cultural History of Perception«, Lou Witte is working with Jana Storch and Lennard Wolf on the gendering of voice assistant technologies, such as Siri and Alexa. The working title of their research is »Voice – Technology – Identity«. The relationship between the perception of self and others serves as his point of departure for an exploration of vocality and gender. Building on this joint research, Lou Witte also examines so-called gender fraud cases in the United Kingdom. His work addresses the potential that digital spaces open up for trans* people to express their identities and juxtaposes this with the risks that it poses, such as being portrayed as impostors.
