Lexi Cowden is an American actress known for her voice role as Shoko Nishimiya in the English dub of the anime film A Silent Voice. Her performance in the film is notable for the authenticity she brought to the character, as Cowden, like Nishimiya, is deaf. Her casting was a significant point of discussion and praise upon the film's English dub release. The English dub for A Silent Voice was produced by NYAV Post and directed by Stephanie Sheh.

Cowden's role as Shoko Nishimiya in A Silent Voice marked her debut in voice-over work. She was submitted for the role by her agent and was guided through the process by her husband, who is also an actor with experience in the voice-over industry. In an interview, Cowden described the experience of voicing Shoko as healing, drawing a connection to her own experiences with bullying in her youth. She also noted the challenge of working in a sound booth and relying on cues from the directors due to her deafness.

While A Silent Voice is her most prominent and widely recognized credit in anime, there is no public information available detailing other voice acting roles in the medium. Cowden has mentioned she is a professional actress who has been acting since childhood and has continued to work on other projects and in directing following her debut in anime.
