Maria CHOIR is an immersive human-AI musical installation that invites participants to explore the boundaries of singing and listening through real-time interaction with an AI. This artwork leverages a model trained on the voice of singer Maria Arnal, enabling a unique duet between the visitor and AI that evolves with each interaction, becoming a choir. Set within a dark, intimate space, the installation features a transparent plinth revealing its inner workings, surrounded by speakers that envelop participants in a rich tapestry of sound. An AI-animated avatar guides users, morphing in response to their vocal inputs, creating a personalized, dynamic experience. Maria CHOIR is not just an artistic experiment but a social interaction on novel AI musical live tools, collective datasets, consent and the potential of synthetic voices to extend beyond mere replication of human capabilities.
