The exact origin of this short line is not widely documented, so its life online is mainly as a reaction and transition sound passed between short videos and soundboards. Creators use the humans address to frame ordinary people as if they are being observed by an outsider, alien or narrator, which gives everyday clips a mock serious tone. That simple setup explains its lasting use: one short announcement can turn a normal reveal, mistake or announcement into a joke without needing extra context or dialogue.
关于此声音
A short voice clip of a character cheerfully saying guess what humans, used as a playful reveal, greeting or plot twist moment in edits and memes.
This is a brief voice line in which a bright, slightly theatrical speaker announces 'guess what humans' as if delivering big news to a room. The delivery is upbeat and a little mischievous, with the emphasis landing on humans like the start of a reveal. It lasts just long enough to register before it ends, which makes the line feel like a punchline setup rather than a full sentence. Viewers instantly expect something surprising, silly or dramatic to follow, so the clip works as a quick attention grab before a cut.
