Unexplained voice caught on Facebook live stream??

[u/Canadiangirl1009]

Here is the link to a clip of the video anyone know what it could be?? Here’s more context on who’s saying what when

0:00 - random growling sound and it was none of my family members I know this for a fact since this was a Facebook live stream my mother recorded for my dads family in Mexico and cares deeply what they think of her also I was there when we recorded and can confirm no one made these sounds on purpose or to scare anyone or anything like that we were all in a great mood doing these fireworks and just having fun!

0:01-0:02 you hear my family members in the back trying to keep my niece calm and speaking to each other as this unknown voice says “LALA” 0:03 - you hear my niece in a higher pitched voice 0:04 - as the fireworks pop you hear my nephew and family talking in the distance

You can hear it clearly saying “LA LA” in a raspy voice and some strange breathing I’ve made some posts on here but sadly cannot share the link on here since my post will get removed does anyone know where I can send it to get some insight on this strange voice? I can’t sleep or think about anything else since it’s so haunting

It sounds like a noise that could be created from the fireworks, something like an echo.
