Her performance has received positive to mixed reviews. Many fans praise her voice as being sexy, and higher-pitched like Rouge's previous voice actress, Lani Minella. Some fans have said her voice is the most suitable for a girl of Rouge's age, but others have felt that she makes Rouge sound too promiscuous.
- Despite being fluent in French, Karen has not provided the French voice of Rouge since Sonic Generations. However, one of her lines in Sonic Free Riders has Rouge saying "magnifique!" - meaning "magnificent!" - whenever she lands a trick.
- Strassman is a naturalized French citizen; she is also fluent in French.
