Voice changer sounds like this became staples of short-form comedy because they need no explanation, the effect itself is the joke. Clips labeled cambio de voz circulate mainly in Spanish-speaking meme and WhatsApp audio circles, where they punctuate identity swaps, fake announcements and playful impersonations. Their staying power comes from versatility, the same four seconds can sell a prank, a skit or a gaming moment. As long as creators play with disguised voices, this kind of transition stays in rotation.
