Strange Voice Caught on video during practice

Warning. Turn your volume down. I increased the sound level on video

I was going over some videos and heard a strange voice that I don't remember hearing while practicing. It's one of those things that is out of place.
As of date, no one recognizes the voice as something that comes from their smart phone or tablet. This voice wasn't heard by anyone else during practice.

My wife is the one asking if anyone heard a voice. There were only 5 people in the room. 2 fighting, 2 filming, and a person off screen.

What does it sound like the voice is saying? Here's the video

"I see dead people"

But seriously, I couldn't make it out.

Sorry, I didn't hear anything.

The voice happens around the :33 mark. exactly at the same time I kick. My first guess is that it was a phone app that was running in the background but the no one recognizes the sound as part of any apps that they own. I guess my kicks have built in sound effects.

I'd go with that answer. It's much more fun than the idea of a stray app sound.

I hear something but I can't make out it what it is.
