She would do well to spend some time around LG or even LJ and learn how to project better.
That personality and passion when speaking is kind of needed for both men and women when talking into the camera.
You need to draw the viewer in, so it doesn't become boring. It's a natural skill set that most don't have. You have to speak with the kind of personality that isn't always natural in real life, because it can be obnoxious in normal conversation. Some people can just be themselves, others have to play a character and exagerarate their personality, which isn't comfortable.
It's tougher for women too, because if they don't find the perfect balance, they can be accused (sometimes rightly sometimes wrongly) of sounding shrill or annoying.
Only ex players, or someone with some type of notoriety can get away with having a softer spoken, less enthralling personality on camera. Even then it's noticeably worse, we just accept it, because they provide an experienced perspective the regular media personalities don't have.
