Old Cherry Orchard Cemetery - Possible EVP

On playback I notice an odd sound at 6 seconds, is it my phone or a weird voice?

Along with the sound I see two white rods that appear at about 13 seconds, make a vibration-like sound then disappear. Is that a video glitch? I know my video wasn't set to best quality on my cell phone, but I've never seen that before.

This cemetery is hidden off of Tod Lane on the corner of Taconic Road in Greenwich, CT.

I'm not sure the name of it and have a hard time pinpointing which one it'd be off of www.findagrave.com.
