CoeFont Recreates President’s Voice After He Lost it to ALS

Digital Hollywood University (DHU) reached out to Coefont with a request to replicate the voice of the university’s principal, Tomoyuki Sugiyama. Unfortunately, Sugiyama had lost his voice due to amyotrophic lateral sclerosis (ALS). Normally, voice recordings are made before an individual loses their voice to create natural AI voices in a process known as voice banking. Despite this challenge, Coefont accepted the project and collaborated with DHU to recreate Sugiyama’s voice using high-quality recordings of his past lectures and other sound sources. The team successfully replicated Sugiyama’s tone, sound, and inflection to enable him to communicate with his own (AI) voice once again.

Comment from Mr. Kazuhiro Ikeya, Secretary General, Digital Hollywood University

DHU has a long-standing history of collaboration with industry leaders, allowing our students to learn in a hands-on style of learning. CoeFont allowed us to research AI voice synthesis by participating in a project to recover Principal Sugiyama’s voice using past recordings. 1 in 100,000 people are affected by ALS, and one of them is our principal, Mr. Sugiyama. We hope that this project and technology will be used to aid ALS patients and their families.

Comments from CoeFont CEO, Shogo Hayakawa

At CoeFont, our original goal was to empower all creators and provide them with a voice. We were pleasantly surprised to learn that our platform has also found use in the medical field, where it is being utilized by medical institutions and individuals who are at risk of losing their voices. Recently, we were approached by Digital Hollywood University to develop a digital voice for their principal, Mr. Sugiyama. While working with DHU on this project, my team and I have gained a much deeper understanding of the social impact that our technology can provide. We are more determined than ever to make digital voices accessible to everyone and leverage our platform to benefit society.
