| Outline of Final Research Achievements |
In this study, visualization of voice was investigated. The authors successfully visualized voice that was radiating mainly from the mouth and chest toward not only the front but also the sides and back. The voice of a proficient vocalist radiated mainly from the chest over a larger zone compared to a beginner and contained more harmonic components. When two persons were vocalizing a tone of the same pitch in unison, a phenomenon was observed where sounds seemed to be connected in the space between them. Currently a sound camera is still expensive and has not gained popularity. Therefore, verification of the model in actual training by using near-infrared spectroscopy (NIRS) is still in the process of research.
