Stephanie Hsu has established herself as a versatile voice actress in animation, with several notable roles in anime-influenced and Western animated productions. She is the English voice of Crane, a princess who becomes a rebel fighter, in the second episode of Star Wars: Visions Volume 3, titled The Song of Four Wings, which was released on Disney+ in October 2025. Her character is described as fearless and kindhearted, protecting a Force-sensitive child from the Empire on a snowbound planet. The role expands her presence in the Star Wars galaxy through this acclaimed animated anthology series that partners with Japanese animation studios.

Beyond Star Wars: Visions, Hsu has voiced characters in other significant animated projects. She played Golden Glider in the 2024 series Kite Man: Hell Yeah!, and Dr. Sleech in The Second Best Hospital in the Galaxy in the same year. Her other animation voice credits include Zhen in Kung Fu Panda: The Dragon Knight (2022), Vontra in The Wild Robot (2024), and a role in Blue Eye Samurai (2023). She also voiced the Mayor's Wife in the 2023 animated film The Monkey King.

In upcoming animation, Hsu has been cast as Margot in the Netflix animated film Steps, a reimagining of the Cinderella story that focuses on the perspective of the so-called evil stepsisters. In this film, her character is transformed into a frog after a magical accident, and the story follows her sister Lilith, voiced by Ali Wong, as she tries to reverse the curse. The film is expected to be released in 2026.

Hsu comes to voice acting with a background in both screen and stage performance. She is widely recognized for her live-action roles, including her Academy Award-nominated performance as Joy Wang / Jobu Tupaki in Everything Everywhere All at Once (2022), as well as roles in Shang-Chi and the Legend of the Ten Rings (2021) and the television series The Marvelous Mrs. Maisel. Her voice work in animation draws on the same emotional range and comedic timing she has demonstrated throughout her career, allowing her to bring characters ranging from a rebel princess to a cursed stepsister to life.
