She was the very first voice actress for Betty Boop, debuting in the cartoon short
Dizzy Dishes (1930). She was hired because she sounded like entertainer
Helen Kane, for whom the character was based. Hines and several other actress voiced Betty until
Mae Questel took over the role in 1931. When Questel, who was just beginning to raise a family, refused to move with the Fleischer Studios staff from New York City to Miami, Florida, Hines was hired to replace Questel in both the Betty Boop and Popeye series in 1938.
