For the background: Myself and 3 friends were in my den, recording ourselves playing a board game. There were no electronics on (TV, Video Games, etc), and there was no one else in the house. We have no neighbors, and our house is very isolated. Also worth noting is that we were using a uni-directional microphone, so any sound from any other direction would not have been caught.
Here's what we caught. You will hear a few people talking. The important part is you will hear me say something like "Is it my turn?", then a female friend reply "Mmm-Hmmm". After a few seconds of silence, another voice pops up that is not one of us, and no one heard at the time. This is near the 14-second mark.

I'm not gonna post what I think it says, I'd like to hear your thoughts. Enjoy!
