Solipsist explores language as a closed system through speech recognition software and a receipt printer. This project takes speech recognition as the paradigmatic example where linguistic expression meets contemporary technology. Taking Mel Bochner's text Serial Art, Systems, Solipsism (1967) as a point of departure, Solipsist explores the implications for free expression when speech is inscribed within machine listening systems. The form of the receipt brings ideas of validation and evidence to the project--the viewer leaves with proof of having spoken, filtered through the impassive arbitration of the technical-administrative system. The viewer can say whatever they want, but the system only hears them in the finite terms of the language it knows–-in this case, the artist’s words.
