Miller got the role of Lisa after the original casting director heard her do a voice that had a lisp and figured she would be a perfect fit.[1]
Of the cast members who voice the Loud sisters, Miller is the oldest.
Ironically, she voices Lisa, the second-youngest sibling. Even more interestingly, Liliana Mumy, the youngest of the sisters' voice actresses, voices Leni, the second-eldest sibling.
