She also dubs actresses such as Aishwarya Rai and has voiced Lois Lane for Amy Adams in several DC Comics films. Her work extends to western animation, where she has voiced characters like Princess Courtney in Barbie in the 12 Dancing Princesses, Rainbow Dash in the early seasons of My Little Pony: Friendship is Magic, and Velma Dinkley in Scooby-Doo! Mystery Incorporated.

A defining characteristic of Jakobeit's career is her long-standing and consistent association with specific roles, most notably Ran Mouri in the Detective Conan franchise. This recurring collaboration with the same character across hundreds of episodes and numerous films over two decades highlights her significance in the German dubbing industry for anime. Her ability to maintain character continuity across a sprawling series is a notable achievement in her field.
