Uchida first noticed the problem last spring, and she suddenly lost her voice at a Love Live! performance at Tokyo Dome.
Uchida is best known for playing Kotori Minami in Love Live! School idol project.
This season, Uchida is voicing Mai in Ai Mai Mi: Surgical Friends, Kaban in Kemono Friends, and Marina in Chain Chronicle: The Light of Haecceitas.
Voice actress Aya Uchida announced on her blog on Monday that she took two weeks off around the end of the year to get surgery for a vocal cord nodule.
