Yuma Shirahata Software Engineer
Graduated with a Master's degree from the Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo, in 2021. Joined LINE Corporation as a new graduate in April of the same year. Since October 2023, I have been in my current position. I am mainly engaged in research and development of speech synthesis, working on the development of high-quality emotional speech synthesis models and foundational models for speech generation using large-scale unlabeled speech data.
