Loquendo is the text-to-speech engine behind a whole era of Spanish-language YouTube, where creators had its robotic voices narrate stories, creepypastas and comedy sketches through the late 2000s and 2010s. The exaggerated 'buaaa' cry became one of its signature gags, a synthetic sob editors inserted whenever a character broke down. Clips of it circulated in meme compilations and WhatsApp audio chains across Spain and Latin America, and it survives today as shorthand for melodramatic, obviously fake sadness in short-form videos.
