So I'm wondering if it's possible to turn my Lumia 902 (windows 8 phone) into a wireless mic.

I would plug in a headset mic, transfer it vie bluetooth (or maybe wireless?) to either my windows laptop, or to my android tablet, which would have speakers plugged in, to make my voice louder.

I'm a teacher, and my students sometimes find it difficult to hear me, so if I could make this work that would be amazing.
