Mixed sounds can be separated from multiple sound sources by utilizing a microphone array and signal processing. We believe that promotion of interest in this technique can lead to significant developments in future science and technology. Consequently, in order to experience this technique, we designed a language game for children called “KIKIWAKE 3D” that uses a sound source separation system with the aim of arousing children's interest in this technology. In this paper, we discuss the development of a spherical microphone array with threedimensional directivity introduced to make the game more interesting and to facilitate a larger number of participants.
