I recently took this video of my dogs playing in my living room, when I took it I was home alone and there were no TV's on at the time. The dryer is on and is the rumbling sound in the background. But the breathing is not mine, nor is the voice. I also live in a very quiet neighborhood and if someone was talking outside I would have heard it, and I head no one talking when I was taking the video. The voice is heard twice and is pretty faint so I recommend wearing headphones. I am pretty sure I have figured out what is being said and am curious to see if you all hear it too.
