Background

Speaking is essential for health and communication, but voice can be affected by illness, aging, or lifestyle. Voice rehabilitation has mainly relied on in-person sessions with specialists, facing challenges such as professional shortages, regional variability in treatment quality, and difficulty ensuring continuous support.

Description and Advantages

Kyoto University researchers developed a new voice training technology that lets users set target vocal characteristics and receive real-time scoring of how closely their voice matches them. By combining an acoustic analysis method (Fig.1) based on a proprietary algorithm focusing on noise and harmonic energy ratios with MR (Mixed Reality), this technology intuitively visualizes timbre and pitch, enabling game-like training (Fig.2). It can be used in clinical voice rehabilitation as well as in karaoke systems and home health tools, providing a fun way to support "vocal health."
