Ouaknine has expressed that dubbing has been the most welcoming branch of the acting profession for her compared to film or theater. She finds gratification in working as a behind-the-scenes performer, noting that while she initially did not consider voice acting at the start of her career, training and mentorship from established professionals helped her develop the necessary skills for the discipline. Her vocal range covers young female voices from children to young adults, with a medium to low tone, and she speaks English with a British accent as well as Spanish.
