Harry Yeff, also known as Reeps100, is a London-born, neurodivergent artist and technologist specialising in voice, AI and technology-based performance. For over fifteen years, Yeff has been visualising the voice and is globally recognised as a leading figure in voice-technology experimentation. His performative installations and machine-like vocal ability have attracted a worldwide following, amassing over 100 million views online. 

Yeff has exhibited internationally at leading museums, festivals and design weeks including the Museum of Arts and Design (New York), Tate Britain (London), Art Basel Miami, the Sundance Film Festival and Davos. His live performances and talks have featured at Google Exec, the United Nations, SXSW, Glastonbury and TED, where his voice-driven performances continue to redefine what it means to communicate and create with technology. 

Yeff’s practice centres on the human voice as both medium and data, using advanced technologies to extend its expressive and sculptural potential. His work explores the evolving relationship between humans and intelligent machines, transforming sound into visual form and performance into digital artefact. Through AI collaboration, he examines identity, empathy and the boundaries of self-expression in the age of synthetic media.
