Initially, Mary Kay Bergman did every female voice until her death in 1999. After that, she was succeeded by Mona Marshall and Eliza Schneider shortly afterwards. Schneider later left the show in 2003, then April Stewart replaced Schneider the following year in 2004.
I guess you could argue that April Stewart and Nicole Oliver look very similar to one another. The only differences are April Stewart has blue eyes while Nicole Oliver has brown eyes. Another difference is that April Stewart is American while Nicole Oliver is Canadian. And lastly the both of them were born one year apart from another April Stewart was born on April 1, 1969 while Nicole Oliver was born almost one year apart on February 22, 1970. I bet you could argue their voices sound similar too. I mean the similarity of their voices are amazing. I would’ve never been able to tell one from the other. I bet Nicole Oliver would’ve done some of the Canadian voices in South Park one day. Along with Matt Hill and Brian Drummond. April Stewart also sang 12 days of Christmas with other voice actors, including Tara Strong. Which herself is also Canadian.
