I want the arduino to know when a person is talking. I can have sensors on the person's body which I think will be needed. I'm currently thinking of analog resistive bend sensors or a magnet with a hall effect sensor. I will be sure to use a battery and not a wall wart.

How to detect when a person is talking?
