To signify the character's 8 years living in America, Johnson was required to use an American accent while playing Vicki. She was given a voice coach and a sheet of American phrases to practice weekly. She commented, "It is hard work, but it's becoming second nature now. As soon as I know that I'm Vicki, the accent just comes with it." After 6 months in the role, Vicki dropped the American accent. Johnson explained the reason for the change in 2004: "The producers knew that I had to have an American accent when I came into the show because my character had been living in America but it's not the kind of accent that you'd want to have for a long time on a show like "EastEnders". It's not something that's going to fit in for a long period of time. What would have been perfect would have been to have it gradually fade out, but as you film 8 episodes at a time, this would be nigh on impossible. The decision was made that in the story Vicki was coming to terms with the fact that she wanted to live in London so therefore she was going to make a conscious effort to fit in with everyone around her and blend in with London life."
