I can't make anything out from that. Maybe if someone isolated the vocals, but I doubt there's anything interesting there.

I can't make sense out of it. It kinda sounds like it's been "filtered" like Animalese or the Inkling language. The first thing they say sounds more like, "hello?" than any Japanese word.

Isolated Vocals

EDIT: I put it by TurboScribe and it detected that the last part goes "この動画の字幕は視聴者によって作成されました. ご視聴ありがとうございました." ("kono dōga no jimaku wa shichōsha niyotte sakusei saremashita . go shichō arigatōgozaimashita") ["Subtitles for this video were created by the viewers. Thank you for watching."]

I tried putting it by TurboScribe:

There's no way it got that from the isolated vocals you posted in the other comment. Here's me reading what's written there. You'll find they don't sound at all like each other.

Have you tried reversing the audio?

Huh. I'm kinda new on Japanese. Was learning, but my depression issues made me lose motivation. I honestly thought it sounded alike 😅

Haha, could be that I'm just not hearing it. And gimme a shout if you ever feel like learning a phrase or two in Japanese; I'd love to help you out. Thanks for using the community!

Reversed Audio

Nah, I trust you more. You're the one who knows Japanese here. Also, your PeerTube link isn't opening for me. Maybe send the file to 0807.st?

I thought I heard an ありがとう~~~ and やめよう but I might just be imagining it. I also thought it might be reversed from the isolated audio, but some of it still sounds backward (or at least heavily processed). My wife didn't immediately notice anything in either forward or backward (she's a native speaker).

So, do we conclude this is just gibberish?

Sample size seems a bit small for that, but I've got nothin. Maybe if I played with it myself in headphones for a while, but I honestly don't have time to do so. Sorry :/
