A "voice" instrument based on vocal tract models by using soft material for a 3D printer and an electrolarynx

In this paper, we propose a "voice" instrument based on vocal tract models with a soft material for a 3D printer and an electrolarynx. In our practice, we explore the incongruity of the voice instrument through the accompanying music production and performance. With the instrument, we aim to return to the fact that the "Machine speaks out." With the production of a song "Vocalise (Incomplete)," and performances, we reveal how the instrument could work with the audiences and explore the uncultivated field of voices.
