Ambient Lighting with Bluetooth Shield Sensors - Feasibility Question


I'm working on a project for school. I have a box with lights set up in one area of the room with my arduino. I want to put a microphone on a person in a different part of the room to detect their voice (and the ambient noises in the room as they move around), which will change the temperature of the RGB leds. Can I do this by putting a bluetooth shield attached to a microphone on that person?

The larger goal of the project is to place different sensors around a room that pick up changes in temperature/moisture/ambient noise levels which will effect different aspects of the lighting system I create.

I hope this was clear enough, I'm trying to gauge feasibility before buying because I'm on limited budget.

Thank you.
