Estel Tort is a Spanish voice actor known for her work in dubbing, particularly for providing the Castilian Spanish voices for prominent actresses and characters in film and television. Born in Molins de Rei, Barcelona, in 1991, Tort's passion for performance began in childhood, leading her to study theater from the age of eight. She initially aspired to be a radio journalist, captivated by the performative aspect of the medium. After not passing the entrance exams for the Institut del Teatre, a friend introduced her to the world of dubbing. She enrolled in a dubbing course and, upon discovering her singing ability, went on to study musical theater at the Aules school of performing arts.

Tort began her professional career in her early twenties, finding steady work in the industry by the age of 25. She approaches dubbing as a performance art requiring the same dedication and physical discipline as elite sports, emphasizing that voice actors must transmit a character's essence while matching a pre-existing performance. This intense use of her voice led to a significant vocal cord injury in 2022, which required surgery and nearly a year of recovery, an experience she has spoken about publicly to normalize such injuries in the profession.

While her work is extensive across various media, Tort has built a notable career in dubbing animation and Japanese anime. She is the regular Castilian Spanish dubbing voice for actresses Zendaya and Jenna Ortega. Among her most recognized anime roles is Shōko Komi, the protagonist of the series Komi Can't Communicate. In this role, she voices a beautiful high school girl whose struggle with severe social anxiety renders her practically mute, a performance that requires conveying deep emotion through limited dialogue. Her other anime credits include voicing Lea in the 2021 animated film Monster Hunter: Legends of the Guild. Tort has noted that dubbing anime presents unique challenges, as the original Japanese performances are often highly intense and vocal, which can be demanding for the voice actor. Beyond anime, her voice work also includes the role of Galadriel in The Lord of the Rings: The Rings of Power, for both its Catalan and Spanish versions, as well as characters in major productions like Barbie and Squid Game.
