While Melissa Rauch was finding her voice on "The Big Bang Theory," she was also creating unique voices for cartoon characters. In fact, Rauch's impressive impressions and vocal range led to her landing roles in "Ice Age: Collision Course," "Sofia the First," and "Jake and the Never Land Pirates."

"You approach doing [voiceover work] the same way you would any other acting role," Rauch explained to "The Movie Times." The actress continued, joking, "Except for the fact that you don't have to wear makeup, and you do it without Spanx."

When she landed the role of the bad gal in "Batman and Harley Quinn," Rauch used her Jersey roots for inspiration. "I knew Harley had a higher pitched tone, and a bit of a New York accent," she explained to Empire. Rauch continued, saying, "I come from a New Jersey family where everyone could be former gun molls, [so] I wanted to give a nod to my background without being as shrill." 

Apparently, you can take a girl out of Jersey, but you can't take the Jersey accent out of the girl.
