In this paper, we introduce the speech-based interactive and immersive installation, Ephemera, as an artistic response to the linguistic taboos encountered in daily communication, prompting audience reflection and thoughts. Within this project, we symbolize the dissemination chain of language through a computational ecosystem. Utilizing the surreal 'virus' as an embodiment of banned words, we employ generative models for visual representation, leverage large language models for communicative agents, and use machine learning for behavioral engines, ultimately simulating a digitally autonomous micro-organism world of forbidden language. We contextualized the speech-to-content generation process to draw the audience's attention to the power and constraints of language. Additionally, we examine AI's comprehension of censored words and ethical considerations. Finally, our artistic project proposes the aphorism "Language as a virus, art as an antibody," offering novel perspectives on language taboos and art-technology intersections.
