How to stream with multiple cameras, so that the person who speaks will have their camera active.

Im going to stream a 25hour radioshow, and I wonder if anyone knows how I can get a camera to activate using sound. Like if person A talks, their camera will film them, and then if person B talks, the camera will film them. I know this is possible, as ive seen this done before.

Also, do I need any extra equipment for this, like hardware or special software.
