Chinese text-to-speech voices became widely available through online voice generators and translation apps, where users could type English or Chinese text and hear it read aloud in Mandarin. Creators soon began saving those clips for short-form video, using the flat, formal delivery to dub captions, prank friends, and add an unexpected voice to memes. The sound spread on TikTok and other platforms because the contrast feels instantly recognisable, even to viewers who do not speak Chinese. It remains popular as a quick way to add narration without recording a voice.
