Delaney is best known for being replaced by Karen Strassman.
According to the context she is best known as a voice actor in several roles before she was replaced in one of them. My statement concludes that she is best known for being replaced, not the work she has done in her career. Clearly it is incorrect, don't know why the AI didn't pick it up.
