With reality shows such as "The Voice," "X Factor" and "American Idol" dominating network television, it's not surprising that vocal coaching is hot business.

Tara Simon should know. She's on both sides of the trend. The performing arts graduate and vocal coach runs her own studio in Atlanta. She also sings at corporate functions, weddings and entertainment industry events.

"I've been singing my whole life. I actually gave my first voice lesson when I was 14," said Simon.

She believes reality shows are one reason demand has surged. Simon herself is a contestant on the current season of "X Factor."

"I also think the bad economy has something to do with it," she said. "When you feel you have nothing to lose, you're more inclined to pursue what you really love and truly have a passion for doing."
