The exact recording behind this clip is undocumented, which is common for user-uploaded soundboard audio: short reaction snippets circulate without credits and get reused purely for their tone. Two-syllable Mandarin reactions like this one travel well because even listeners who do not speak the language read the flat delivery as skepticism or weary agreement. Its quarter-second length makes it a favorite for fast meme edits, chat replies and compilation punchlines, where a longer voice line would break the rhythm.
